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.)

1、《小波图像分解与重构程序存在的问题与解决办法》 我编写程序时尽量实现模块化，方便不同功能程序之间的调用。以上程序实现了一维、二维小波分解与重构的功能，接下来我们就可以此为基础，探讨小波信号压缩和图像融合等技术了。(1, " Wavelet image decomposition and reconstruction process problems and solutions" when I try to modular programming, to facilitate calls between different functional processes. Program achieved more than one-dimensional, two-dimensional Wavelet function, then we can take this as the basis of wavelet signal compression and image fusion with the.)
