OFDM基本原理仿真程序，本程序是基于IFFTFFT实现的OFDM系统仿真(The basic principles of OFDM simulation program, this program is implemented based on the OFDM system simulation IFFTFFT)

盲源分离算法，该算法能够从混合信号中分离出原始信号。已用MATLAB验证：程序从正弦信号和随机噪声信号的混合信号中成功地分离出了正弦信号和噪声信号。程序保证能正确运行。(Blind source separation algorithm, which can be separated from the mixed signal the original signal. Has been verified with MATLAB: Program from the sinusoidal signal and random noise signal, mixed-signal successfully isolated sinusoidal signal and noise signal. Program guaranteed to run correctly.)

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. )
