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

此程序为书上源码，功能是描述16QAM载波调制信号在AWGM信道下的性能，有误码率分析图-This program is a source book, the function is to describe the 16QAM modulation signal performance at AWGM channel has BER analysis chart

16QAM误码率分析，理论与仿真值比较及画图-16QAM BER analysis, theory and simulation value comparison
