Matlab设计实例30例精解，里面有详细的讲解过程和源代码以编程用到的数据(Matlab examples of refined solution design 30 cases, there are detailed to explain the process and source code used to program data)

poisson问题有限元求解通用程序(线性元). 压缩包内exp.m包含了一个实际问题,matlab下直接运行即可,如效率不高,可适当修改网格参数h.(poisson problem of the finite element procedure for solving general (linear million). exp.m compressed package contains a real problem, matlab can be directly run, such as the efficiency is not high, may be appropriate to amend the grid parameter h.)

线阵波束形成MATLAB语音程序编辑， 频域自适应，时域自适应(Voice line array beamforming MATLAB program editing, adaptive frequency domain, time domain adaptive)

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.)
