中文说明：
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。
English Description：
The random data generated by Matlab function or module is sent to Gaussian white noise channel after 16QAM digital modulation; After the receiving end demodulates the data with 16QAM, it makes bit error rate statistics with the source data; The relationship between bit error rate and signal-to-noise ratio is analyzed
