一些常用的通信系统仿真，16qam、64qam误码分析，turbo。,Some commonly used communication system simulation, 16qam, 64qam error analysis, turbo.

本程序主要实现16QAM的误码率分析，包括载波相位偏移和判决电平的误差对误码率造成的影响，里面附有自己的解调程序-This procedure mainly realize 16QAM BER analysis, including the carrier phase offset and decision level of errors on the error rate impact, which with its own demodulation process

与已有的代码相比，本代码不仅包含调制解调、星座图、误码率等已有功能，更添加蒙特卡洛仿真，具有更好的性能，程序会产生一些图，能看清楚调制解调的过程中一步一步的编解码过程。-Compared with the existing code, the code contains not only the modulation and demodulation, constellation diagram, such as bit error rate for existing function, mor
