课程设计两个程序：一：数据帧（程序每帧设置为400bit)在有扰信道传输时，采用Turbo码进行编译码。并仿真Log-MAP译码算法在不同迭代次数下的性能。
二：实现有扰信道中，不同信噪比下，采用MAP译码算法的Turbo码的性能。
以上各主程序均有做比较详细的程序注释
可直接运行turbo_main.m或LogMAP.m，稍等片刻即可观察到仿真结果

Turbo码，LDPC码（低密度奇偶校验码）均具有接近Shannon限的性能，
是目前便译码研究的热点。Turbo码在低信噪比情况下的性能优于其它各种编码
方式。而LDPC码的描述简单，具有较大的灵活性，当码长足够长时具有比Turbo
码更为良好的性能，其译码复杂度低于Turbo码。-Turbo code, LDPC code (LDPC) all have close to Shannon limit performance, it is the firm' s resear
