LDPCBSN
LDPC码既低密度奇偶校验码(Low Density Parity Check Code,LDPC),它由Robert G.Gallager博士于1963年提出的一类具有稀疏校验矩阵的线性分组码,不仅有逼近Shannon限的良好性能,而且译码复杂度较低, 结构灵活,是近年信道编码领域的研究热点,目前已广泛应用于深空通信、光纤通信、卫星数字视频和音频广播等领域。LDPC码已成为第四代通信系统(4G)
(LDPC codes BER simulation under AWGN channel. MacKay-Neal based LDPC matrix. Message encoding uses sparse LU decomposition. There are 4 choices of decoder: hard-decision/bit-flip decoder, probability-domain SPA decoder, log-domain SPA decoder, and simplified log-domain SPA decoder.)

需要将音乐文件bhk_med.wav放于D盘根目录下才可以直接执行程序,或将程序中的音乐文件路径指向当前目的音乐所在的地址。背景音乐可以更换,甚至可以自行合成。(Music files need to be put in the D bhk_med.wav root directory before you can run the program directly, or to program the music file path to the address of the current purpose of music is located. Background music can be replaced, even on their own can be synthesized.)

fe_sdofID_2
Purpose:
build the ID array of system dofs to apply displacement constraints
Synopsis:
[csdof,sid]=fe_sdofID(discons,ndof,nnode)
Variable Description:
csdof - the number of system dofs after constraints applied
sid - ID matrix of system dof formatted as nnode*ndof
discons - matrix record the node of displacement constrain
ndof - number of dofs per node
nnode - number of nodes in system(Purpose:

asymppdc
这是第一版的AsymPDC工具包。用来处理PDC,gPDC和iPDC有关内容。运行环境为Matlab,并且要求至少Matlab中预装了3个工具箱:控制系统,信号处理和统计工具箱。(This is the first public release of AsympPDC package. It deals with the asymptotic statistics for PDC, gPDC and iPDC.
AsympPDC runs under Matlab and is a practically self-contained except for requires routines from three Matlab toolboxes: Control System, Signal Processing, and Statistical.
It is not extensively tested yet. It was partially tested under Windows, Macintosh and Linux environments with Matlab version 7.0 and higher.
Please report any incompatibility to ksameshi[at]usp.br or baccala[at]lcs.poli.usp.br.
Additionally for cosmetic purposes, the pdc_xplot routine uses several Matlab users contributed codes: subplot2.m (modified old version of supbplot to control spacing between subplots), shadedplot.m (developed by Dave Van Tol), suplabel.m (for label and title plotting in subplot figures, by Ben Barrowes), suptitle.m (contributed by Drea Thomas, for adding title above all subplots), and tilefigs.m (for tiling figures for simultaneous visualization, by Charles Plum))
