说明：  ofdm qpsk 添加循环前缀 信道估计 补偿与均衡 信号星座图(OFDM QPSK add cyclic prefix channel estimation compensation and equalization signal constellation)

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].)

通信中利用匹配滤波，产生斜坡信号，并进行相应滤波(Communication using matched filtering, resulting in ramp, and the corresponding filter)

opnet仿真实例，里面有一些现成的例子可供使用。(opnet the simulation, which has some ready-made examples available.)

信号利用QPSK调制，采用全数字化的频偏估计方法(A full digital frequency offset estimation method using QPSK modulation)

calculating CRC from digital and analog input

说明：  用51单片机完美地解决凝露现象。防止元件老化(The dew phenomenon can be perfectly solved by 51 single chip computer. Preventing component ageing)

线性调频信号和相位编码信号（七位巴克码）及他们的混合调制信号在matlab中的实现(The realization of the chirp signal and the phase-encoded signal (seven Barker code) and their hybrid modulation signal in matlab)
