利用Matlab函数或者模块产生随机数据，经过16QAM数字调制，送入高斯白噪声信道；在接收端使用16QAM解调数据后，与信源数据进行误码率统计；分析误码率与信噪比的关系。-Have the random data using the Matlab function or the module, undergoes the 16QAM digital modulation, sends in the white gaussian noise channel　After the receiving end uses the 16QAM demodulation data, carries on the error rate statistics with the source data　Analysis error rate and signal-to-noise ratio relations.
