对3条固定路径的AWGN多径信道中的QPSK系统进行BER性能仿真（不同p和delay 的取值来分别定义莱斯（瑞利）平坦衰落信道、莱斯（瑞利）频率选择性衰落信道).-For three fixed-path multipath AWGN channel of the QPSK system BER performance simulation (different values for p and the delay are defined Rice (Rayleigh) flat fading

MATLAB上实现的OFDM+AWGN/Rayleigh+BPSK/QPSK/16QAM/64QAM， 并分析EbN0 vs BER.-The MATLAB implementation OFDM+AWGN/Rayleigh+BPSK/QPSK/16QAM/64QAM, and analyze EbN0 vs BER.

first, this project simulates cdma network using 63 gold code over Rayleigh fading channel.then ,compares rake receiver performance with ordinary receiver and theory awgn and theory Rayleigh channel . finally , we observe decreasing ber when number o

无论是那种编码方式，在AWGN信道中的性能都明显由于在瑞利衰减信道中的性能。这一点也符合实际。毕竟AWGN信道是瑞利衰减信道的特殊情况。除此之外，在研究单一编码方式误码率时，样本帧数越大，则得到的误码率曲线就越平滑，较少出现较明显的凸起。(Either way, the performance in AWGN channel is obviously due to the performance in Rayleigh attenuation channel. This is also in l
