GSM 目前还是现在主要应用的移动系统，2G的演进也是目前平稳向三代过度的重要途径，MUROS，EDGE等都是现在技术演进的关键技术，本代码给出了平台搭建中TCH信道编解码技术，希望对你有所帮助。-GSM is still the main application is mobile systems, 2G is the steady evolution over the three generations of an important way, MUROS, EDGE technology

这是GSM增强型全速率语音编解码的C语言源代码，很不错的。-This is the GSM Enhanced Full Rate Codec C language source code, very good.

GSM通信系统包括发送端的编码和调制，接收端的解调和解码。-this is a matlab program

有信道编码，调制，信道估计等，ldpc码的编解码实现，GSM中GMSK调制信号的产生。- Channel coding, modulation, channel estimation, Codec ldpc code implementation GSM is GMSK modulation signal generation.
