C ++ Language in Code Block Based Distribution Sharing Automation

Andy Prasetyo, Abu Nizzan Adami · Zenodo (CERN European Organization for Nuclear Research) · 2018

Dividing inheritance into probelmatika in each region, because it is not yet understood by Islamic law about the distribution of inheritance. Therefore, this research was made to make it easier for people to use the C ++ language in the codeblock application. The results of this study are that the distribution of inheritance using C ++ based on codeblock is more efficient and does not cause conflicts between families, because it is according to shari'ah calculations.

M-ary code-selected space time block code based DS-BPAM ultra wideband system

Zhiquan Bai, Dongfeng Yuan, Haixia Zhang et al. · 2008

In this paper, we present the space time block codes (STBC) based M-ary code-selected modulation scheme of direct sequence bipolar pulse amplitude modulation (DSBPAM) ultra wideband (UWB) system with selective Rake (SRake) receiver and maximum ratio combining (MRC) over multipath channels in order to improve the system performance and transmission rate of the conventional DS UWB system. The system bit error probability is derived and the signal processing algorithm is provided. Simulation is performed with different SRake receiver fingers over multipath channels. The results show the efficiency of the Mary STBC based DS-BPAM UWB scheme in both system performance and transmission rate.

Burst Error Correction for Convolutional Code Concatenated with Hamming code with a block interleaver

Shin Jihwan, Ho-Kyeong Lee · 2020

We consider a concatenated coding scheme which consists of the tail-biting convolutional code as an inner code and the hamming code as an outer code. They are separated by a block interleaver. The size of the row of the block interleaver is fixed to the length of the codeword of the hamming code. We select the interleaving depth, the size of the column of a block interleaver based on the burst error statistics of the outer convolutional code. We assume that the channel is correlated discrete Rayleigh fading channel which is modeled by using FSMC (Finite-State Markov Chain). Our simulation results show that the BER (Bit Error Rate) performance improvement of the convolutional code with the Hamming code.

Study of the block and convolutional code decoding efficiency using a turbo code decoder

Alexander A Sidorenko · Journal of Physics Conference Series · 2024

Abstract An urgent task is to correct errors that occur during the transmission and storage of information. To solve this problem, various noise-resistant codes have recently been increasingly used. Turbo codes have the best correcting ability in data transmission channels with a high probability of an erroneous bit. To obtain the necessary characteristics, various combinations of codes and encoding and decoding methods are used. If another block of information bits is added to the codeword of a systematic block or systematic convolutional code, then it will be possible to implement decoding of such a codeword by a turbo code decoder. The disadvantage of the resulting combined code is its extremely low correcting ability in the presence of errors in the check bits of the codeword. The article shows that the correcting ability of the presented code can be significantly increased by multiplying the decoded values of the check bits by reduction factors.

Inner code rate selection for serial concatenated block codes

M. Bystrom, R.A. Coury · 2003

Typically, appropriate code rates for the constituent codes in a concatenated coding system have been found through the means of heuristic methods and simulations. Herro et al. (see IEEE Trans. Inform. Theory, vol.4, p.212-22, Mar. 1988) first employed information-theoretic techniques to conclude that there is an optimum rate for the inner code of a concatenated block coding system. In this work we expand upon the results of Herro et al. to present a tractable method for determining appropriate code rates as a function of selected system constraints, such as coder block length.

Non-orthogonal space-time block code for multipath channel

Sassan Iraji, Olav Tirkkonen, Ari Hottinen et al. · 2004

We consider non-orthogonal space-time codes in multipath fading channels. For this, both minimizing the effect of the self-interference induced by the non-orthogonal code itself, and mitigating the inter-symbol-interference induced by the channel need to be addressed. We approach the problem by analyzing the example of rate one linear space-time transmissions from four transmit antennas. The starting point is the non-orthogonal ABBA-code minimizing the self-interference, which is one of the rate one quasi-orthogonal codes for four antennas. In addition to applying time reversal on the part of a frame consisting of complex conjugated symbols, the non-orthogonal structure allows for multiple non-equivalent permutations of the transmission symbols. We observe that in addition to separating symbols and complex conjugated symbols, it is essential to interleave the symbols so that time epochs during which copies of the same symbols are transmitted, are far from each other

Some New Properties on Block Matrices Using MATLAB Code

Ahmed A.H. Alkhalidi, Mujtaba Zuhair Ali, Mohsen Naeem Yasser · Mathematical Modelling and Engineering Problems · 2022

In this article, we study some new properties of the block matrices. Introduce the methods for finding the block matrices of any matrix. We prove some of these methods by using the matrix analysis methods. Some results of this paper are proved by using the permutations of matrices of the block matrices. In the last of this study, some examples are introduced to explain the results of this work and we give some MATLAB code in the appendix to explain the results of this article.

Effects of the Latest LRFD Block Shear Code Change

Howard I. Epstein · Engineering Journal · 1996

This paper examines the effects of the required change in the use of the block shear design strength equations resulting from the latest AISC-LRFD code treatment. The latest code either gives the same results as the previous code or is more conservative. The parameters of the connections for which the two treatments differ are presented, as well as the percentages of the differences. On the basis of recently reported experimental results, the need for further refinement of the codes is presented.
