ASK系统的设计与仿真，相干解调及误码率的计算(Ask system design and simulation of coherent demodulation and the calculation of the bit error rate in English)

光通信中采用OFDM时，信号必须为非负实信号，因此通常采用DCO-OFDM或ACO-OFDM技术，此代码为ACO-OFDM(In VLC the signal has to be real and unipolar. Number of schemes in VLC are proposed in order to provide a real and unipolar signal like U-OFDM , Flip-OFDM , spectrally factorized pptical OFDM].)
