考虑雨衰 阴影 和多径影响，抑制载波型差分相位调制，MIMO OFDM matlab仿真,旋转机械二维全息谱计算，仿真效果非常好，真的是一个好程序。- Consider shadow rain attenuation and multipath effects Suppressed carrier type differential phase modulation, MIMO OFDM matlab simulation, Rotating machinery 2-d holographic spectrum calculation, Simulation of the effect is very good, Really is a good program.
