Description: 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
-two programs of Curriculum design : a: Data frames (each frame is setted to 400bit per frame) ,under a interferent channel transmission uses Turbo codes and decodes. including simulation of Log-MAP decoding algorithm performance under different number of its iterations.
2: To achieve the simulate the performance of MAP decoding algorithm for Turbo code,with different SNR that is decided by interferent channel.
Above the main program have to do a more detailed program notes
Can be directly run turbo_main.m or LogMAP.m, wait a moment to the simulation results can be observed
