System Performance Metric, Bit-Error-Rate (BER)

Farinaz Edalat, Charles G. Sodini, Farinaz Edalat · 2003

In today's high-speed wireless communication applications, the simultaneous demand for bandwidth-efficient modulation schemes such as M-QAM and high power-efficiency of elec-tronic components in the system imposes a contradicting tradeoff. On one hand, with the RF power amplifier (PA) at the transmitter antenna being the major power "hungry " block in many such systems, high power-efficiency for the system is obtained when the PA con-sumes most of the little supplied dc power (e.g. from a battery) as RF power, which is the power delivered to the load. On the other hand, at high powers, the PA becomes nonlinear, which becomes problematic when the input to the PA has a time-varying envelope. More precisely, when an M-QAM modulated signal (which has varying envelope and phase) is transmitted, the PA nonlinearity characteristics adversely affect the system performance, such as degradation of the Bit Error Rate (BER). Although linearization and compensation techniques can be used to minimize the above mentioned degradation in system performance, such techniques are mostly not suitable for low-cost and small-size integrated-circuit implementations. As a result, to obtain an optimal

Basing Acceptable Error-Tolerant Performance on Significance-Based Error-rate (SBER)

Zhaoliang Pan, Melvin A. Breuer · Proceedings - IEEE VLSI Test Symposium/Proceedings of the ... IEEE VLSI Test Symposium · 2008

As CMOS scaling continues to decrease and new technologies emerge, feature sizes approach molecular sizes. Due to high defect rates, process variations and quantum effects, manufacturing yields have decreased. To increase the effective yield, error-tolerance, which allows for some defective chips to be employed in systems that can tolerate errors, has been proposed. To support error-tolerance, the acceptability of defective chips must be quantified according to certain measures. A new measure is proposed in this paper, namely significance-based error-rate (SBER). SBER combines two previously studied error-tolerance measures, namely error-significance and error-rate. In this paper we introduce three different ways to quantify the SBER value(s) of a defective chip using built-in self-test (BIST). These techniques cover the following scenarios: (1) multiple copies of a target circuit where at least one copy is non-defective; (2) multiple copies of a target circuit where none are defect free; and (3) single copy of a defective target circuit. For each scenario, the statistical characteristics of the estimation of the SBER value are discussed.

Performance of models in terms of error rate.

Shengjun Ji (6394568) · Figshare · 2024

<div><p>Thyroid disease presents a significant health risk, lowering the quality of life and increasing treatment costs. The diagnosis of thyroid disease can be challenging, especially for inexperienced practitioners. Machine learning has been established as one of the methods for disease diagnosis based on previous studies. This research introduces a novel and more effective technique for predicting thyroid disease by utilizing machine learning methodologies, surpassing the performance of previous studies in this field. This study utilizes the UCI thyroid disease dataset, which consists of 9172 samples and 30 features, and exhibits a highly imbalanced target class distribution. However, machine learning algorithms trained on imbalanced thyroid disease data face challenges in reliably detecting minority data and disease. To address this issue, re-sampling is employed, which modifies the ratio between target classes to balance the data. In this study, the down-sampling approach is utilized to achieve a balanced distribution of target classes. A novel RF-based self-stacking classifier is presented in this research for efficient thyroid disease detection. The proposed approach demonstrates the ability to diagnose primary hypothyroidism, increased binding protein, compensated hypothyroidism, and concurrent non-thyroidal illness with an accuracy of 99.5%. The recommended model exhibits state-of-the-art performance, achieving 100% macro precision, 100% macro recall, and 100% macro F1-score. A thorough comparative assessment is conducted to demonstrate the viability of the proposed approach, including several machine learning classifiers, deep neural networks, and ensemble voting classifiers. The results of K-fold cross-validation provide further support for the efficacy of the proposed self-stacking classifier.</p></div>

Tuning VCP2 and TCP2 Bit Error Rate Performance

Jane Lu, Brighton Feng · 2011

In most customer applications, a high level of decoding bit error rate (BER) performance is required. Since Convolutional codes and Turbo codes are widely used in wireless communication systems, TI DSPs integrate two high-performance embedded coprocessors (enhanced Viterbi decoder coprocessor and enhanced Turbo decoder coprocessor) that significantly speed up channel-decoding operations on-chip. This application note presents the strategies and programming methodology to optimize VCP2 and TCP2 BER performance on TI DSPs. It is assumed the reader is familiar with Convolutional and Turbo coding theory.

On Performance of Full-Rate Differentially Encoded Cooperative Communications:Bit Error Rate Bounds

Chuchat Moolkum, Chaiyod Pirak, S. Jitapunkul · 2006

This paper investigates a performance of differentially encoded cooperative communications achieving full rate in three-user cooperation scenario with a fixed amplify-and-forward protocol. Tight upper and lower bounds on an averaged bit error rate (BER) for such system are also developed. These proposed bounds significantly reduce computational complexity of evaluating an exact averaged BER. Simulation results show that the proposed bounds are tight to the exact one in fairly-high signal to noise ratio (SNR) regimes

Rate-Splitting for Overloaded Multigroup Multicast: Error Performance Evaluation

Hongzhi Chen, De Mi, Zilong Liu et al. · 2020

In this work, we provide the first attempt to evaluate error performance of Rate-Splitting (RS) based transmission strategies with constellation-constrained coding/modulation. The considered scenario is an overloaded multigroup multicast, where RS can mitigate the inter-group interference thus achieve a better max-min fair group rate over conventional transmission strategies. We bridge the RS-based rate optimization with modulation-coding scheme selection, and implement them in a developed transceiver framework with either linear or non-linear receiver, where the latter equips with a generalized sphere decoder. Simulation results of a coded bit error rate demonstrate that, while the conventional strategies suffer from the error floor in the considered scenario, the RS-based strategy delivers a superior performance even with low complexity receiver techniques. The proposed analysis, transceiver framework and evaluation methodology provide a generic baseline solution to validate the effectiveness of the RS-based system design in practice.

Packet Error Rate Performance of IEEE802.11g under Bluetooth Interface

Salim Abukharis, Jafar A. Alzubi, Omar A. Alzubi et al. · Research Journal of Applied Sciences Engineering and Technology · 2014

This study approaches the issues concerning the coexistence of the IEEE 802.11g wireless networks and the ad-hoc Bluetooth networks that operate within the same 2.4 GHz band. The performance of 802.11g is evaluated by simulating the PER (Packet Error Rate) parameter and coverage area. The simulation experiments are based on the worst case scenario presumption, which entails the transmission of HV1 packet which HV1 link requires transmission on 100% of the Bluetooth (BT) time slots using the maximum hop rate of 1600 hops/sec. The paper suggests a practical approach to mitigate the interference using symbol erasures technique through the assessment of the PER parameter at various Eb/No values. The results show that the symbol erasures can effectively mitigate the interference and enhance the performance of the 802.11g.

Design of LDPC decoders for low error rate performance

Zhengya Zhang, Lara Dolecek, Borivoje Nikolić et al. · 2008

Many classes of high-performance low-density parity-check (LDPC) codes are based on parity check matrices composed of permutation submatrices. We describe the design of a parallel-serial decoder architecture that can be used to map any LDPC code with such structure to a hardware emulation platform. High-throughput emulation allows for the exploration of the low bit error rate (BER) region and provides statistics of the error traces, which illuminate the causes of the error floors of the (2048,1723) Reed-Solomon based LDPC (RS-LDPC) code and the (2209,1978) array-based LDPC code. Two classes of error events are observed: oscillatory behavior and convergence to a class of non-codewords, termed absorbing sets. The influence of absorbing sets can be exacerbated by message quantization and decoder implementation. In particular, quantization and function estimation strongly affect which absorbing sets dominate in the error floor region. We show that conventional sum-product decoder implementations of the (2209,1978) array-based LDPC code allow low-weight absorbing sets to have a strong effect, and, as a result, elevate the error floor. Adaptively-quantized sum-product decoders and approximate sum-product decoders alleviate the effects of low-weight absorbing sets, thereby lowering the error floor.

Bit error rate performance of high-speed tunnel communication

Chien‐Ching Chiu, Chi-Ping Wang · 2002

The bit error rate performance for high-speed personal communication service in tunnels with and without traffic is investigated. The impulse response of the tunnel is computed by shooting and bouncing ray/image techniques. Binary data with phase shift keying modulation are transmitted over the multipath channel and coherent match filters are used as receivers. The bit error rate for communication in tunnels with and without traffic is calculated. Numerical results have showed that the multipath effect by the vehicles in the tunnel is an important factor for bit error rate performance. In addition, the effect of space diversity techniques on mitigating the multipath fading is also investigated.

Bit error rate performance of third generation turbo codes

Mohammad A. Bhuiyan, Mohammad Shah Alam, Md. Shazzad Hosain · 2005

Abstract: After the invention of Turbo Codes (TCs) many coding theorist and researchers further tried to improve the performance of these codes. Now the performance of Turbo Codes is becoming closer to the Shannon’s limit. The performance of turbo codes depends on its architectural component and the architecture of TCs is application dependent. So the researchers are trying to develop the standard architecture of TCs for specific application so that its performance becomes optimum. In this paper we analyze the performance, in terms of bit error rate (BER) vs. bit energy to noise spectral ratio (Eb/No) of Turbo Codes that are using in Third Generation Partnership Project standard (Universal Mobile Telephone Systems-UMTS) [10]. This paper focuses on the effect of the variation of the architectural components of UMTS TCs on its performance. In particular code rate, frame size i.e., length of information bits, number of decoding iteration and channel models variations of Turbo Codes are taken into account in studying the performance of Turbo Codes. These effects are shown in the performance curve (BER vs. Eb/N0) of the UMTS standard turbo codes.

Generalized Decision Feedback Equalizer and Its Error Rate Performance

A. Sano, Junichi Yamazaki, T. Akimoto · Transactions of the Society of Instrument and Control Engineers · 1981

Digital data communication systems are degraded by statistical noise and intersymbol interference caused by bandwidth constraints. This paper presents a new class of nonlinear equalizers with simplified structure implemented by digital filter circuits involving only decision slicers, which can approximately give the maximum likelihood (ML) bit estimates. The structure of the proposed generalized decision feedback equalizer (DFE) is obtained by inducing the concept of the decision feedback into the ML bit estimation. This paper also derives the computational methods for lower and upper bounds of the bit error probability and demonstrates that the proposed technique can give a significant improvement in error rate performance compared with the conventional DFE.
