PCM
1、用Matlab绘制带通信号图形
2、用Matlab对模拟信源进行均匀量化
3、用Matlab编制一个函数实现均匀PCM量化编码，并计算量化噪声比(SQNR)
4、用Matlab对不同的量化级数计算出相应的量化噪声比(1, drawn using Matlab graphics bandpass
2, the simulation using Matlab source for uniform quantization
3, prepared using Matlab function to achieve a uniform PCM quantization coding, and calculate the quantization noise ratio (SQNR)
4, using Matlab on a different series to calculate the corresponding quantitative quantization noise ratio)

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.)
