10 Threads found on edaboard.com: Exponential Distribution
Rayleigh channels are almost worst case scenario. In Nakagami-m channel modeling the worst channel has a parameter m = 0.5, while Rayleigh has a parameter m = 1. Also, Rayleigh channel is mathematically more convenient; the SNR distribution is exponential.

if we create a sequence and call these w1...wN with exponential distribution with parameter lambda then we create:
what's name of this distribution?

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...

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.

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.
