说明：  基于OQPSK，高斯信道和瑞利信道的matlab仿真程序(Matlab simulation program based on OQPSK)

ldpc编码的matlab实现，供大家参考(Matlab implementation of LDPC coding for your reference)

说明：  matlab实现的信道指标计算求误码率低的信道(Calculation of channel index realized by MATLAB to find the channel with low bit error rate)

基于MATLAB搭建的超奈奎斯特（FTN）仿真系统(Based on Super Nyquist (FTN) MATLAB simulation system built)

DRM(Digital Radio Mondiale)系统采用OFDM调制方式， 引入了先进的信源信道编码和调制技术，使得AM波段的音频广播质量大大提高，在保持现有10kHz带宽时接近了FM广播的质量[5](DRM (Digital Radio Mondiale) system uses OFDM modulation, the introduction of advanced source-channel coding and modulation techniques, making AM-band audio broadcast quality greatly improved, while maintaining the existing 10kHz bandwidth close to the quality of FM broadcasting [5])

MIMO信道容量的Matlab仿真程序,瑞利信道,得到的是CDF，即累计分布曲线(Matlab simulation program MIMO channel capacity, Rayleigh channel, get the CDF, and that the cumulative distribution curve)
