写CRC编解码程序时，整理的文件，压缩文件既有理论说明，也有源代码。源代码格式用C,VHDL,Verilog。-write CRC codec procedures, collating documents, compressed files both theoretical statements, and the active code. Source code format C, VHDL, Verilog.

采用简化算法和visual C++6.0程序实现DVB-S2 LDPC编解码。包含多种算法，并能直接运行，参考价值巨大。-Simplified algorithms and visual C++6.0 program to achieve DVB-S2 LDPC codec. Includes a variety of algorithms, and can be run directly, the reference value is huge.

Base64编码解码 非常好用 适用C- BASE64_EncodeBase64 applicable codec is very easy to use C++

g.927源码 实现成功的G.729源代码，效果很好的！- --G729 codec code, c language, complete works could be directly translated。
