BPSK with flat fading effects

要求对有3条固定路径的AWGN多径信道中的QPSK系统进行BER性能仿真，并与在理想的AWGN信道中同样系统的BER性能进行比较。熟悉瑞利平坦衰落、莱斯平坦衰落与频率选择性衰落的特点，比较这些衰落信道的误码率。-Required to have three fixed-path AWGN multipath channels of QPSK system BER performance simulation, and in an ideal AWGN channel with the same

运用matlab搭建了MIMO—OFDM系统，并仿真了该系统在awgn信道，平坦衰落和多径信道下的误码率。-Using matlab built a MIMO-OFDM systems, and simulation of the system in awgn channel, flat fading and multipath channel BER.
