寒假期间学习的CDMA/MIMO/OFDM视频课程，给了我很大的帮助，附件是整理的一些课程知识点。音频链接
Modeling Wireless Channel:
Impulse Response:
Frequency Response:
Probability Density Function:
Assuming x,y are independent random variables,
Joint distribution :
Example:What is the probability that the attenuation of the channel is worse than 20db?
Gain of Channel = a2
Wire-line Awgn system
Y=x+n
Probability Density Function of noise
Consider modulation for BPSK
Probability of Error
Example:At SNR=10db.What is the BER for AWGN Communication System ,with BPSK modulation?
Bit Error Rate of Rayleigh Fading wireless channel
Y=hx+n
Received Power : |h|2P
BER of wireless system
Exact BER =
Deep Fade when received power lesser than noise power
Exact Probability of Deep Fade
Approximate Probability of deep fade at high SNR
