I want to generate random signal with exponential distribution (exp(T/tau) tau is my constant) in verilog. Could you please advice me how I should do it?

Basically, if the underlying fading channels are Rayleigh, then SNR follows exponential distribution. That is y0, y1, and y2 are all exponentials, where y0, y1, and y2 are the instantaneous SNR of the direct path, the first hop of the relay path, and the second hop of the relay path, respectively. After generating them, calculate the (...)

IF X and Y are statistically independent (or orthogonal) then the RMS of the combined signal (sum) will be sqrt(X^2 + Y^2) and the distribution will be exponential

Hi all! I would like to ask if there's any advantage in doing OFDM in a flat fading Rayleigh environment?
Also can anyone tell me if there would be any difference in the BERvsSNR results , when we simulate a flat Rayleigh channel and a frequency selctive exponential channel, where each tap follows Rayleigh distribution...
Any answer will be he

I want to find out the cdf
Fx(x)=Pr(X ≤ k)
where "X" is a Rayleigh distribution and "k" is some other Rayleigh distribution with may be different mean and variance.
How can I find it out, somebody help me please.

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.
