Instantaneous receives SNR

[aliazmat]

please somebody explain me that if the channel is Rayleigh faded than Instantaneous receives SNR is exponential distributed wit some mean.

please elaborate it in bit detail.

If you look in the book of David Tse, Fundamentals of wireless communications.

instantaneous SNR is defined as, |h|^2 SNR, therefore if we take square of Rayleigh it becomes exponential distribution therefore the overal instantaneous recieved SNR becomes exp. with mean SNR.

hope this helps.

Thanks for you reply but

As for as I know SNR is the ratio between Signal Power and Noise Power than y we multiply it with |h|^2 why not only with "|h|"
