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.)

parseSize
A tool for OOP overloading of the size() method, imitating I/O conventions of MATLAB s native SIZE.
(This function is an OOP aid for overloading the size() method in user-defined classes. If the user provides the vector of dimensions of a hypothetical array object, parseSize will take care of the main input/output argument processing in a way that imitates the conventions of MATLAB s usual SIZE function.

程序目的:间隔取点
可以自由选取将一组时间序列的采集点:如愿采集点间隔为0.01s,通过程序可自动得到采点间隔为0.05s时间序列。( Program purpose: to take point interval can be freely selected a set of time series of the collection point: to do so collection point interval of 0.01s, the program can automatically be taken through the point of 0.05s interval time series.)
