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.)

师兄的人工势场法避障实验代码，绝对好用，代码精炼，注释全(Brother of artificial potential field obstacle avoidance test code, absolutely everything, code refining, notes the whole)

this file can help to read and write and even graphic changes for videos and images.

鉴于网上合成孔径雷达的资料比较少，上传一些老师给的文献资料，希望对大家有帮助(Given the online synthetic aperture radar data is relatively small, upload some literature teacher, I hope to help everyone)
