WebThis question concerns fading channels in wireless communication, but its essence is still statistics and distributions, so I pose it here. I want to generate (sample) complex-valued coefficients that model the wireless channel by taking into account a constant, a lognormal distribution (slow fading) and a Rayleigh distribution (fast fading). Webmethod for Rayleigh, Rician and Nakagami channels and separately calculate the LCR and AFD for each channel by this approach. Simulated results obtained for all three channels show that the values of LCR and AFD calculated by using the proposed approach are much closer to actual simulated values than what conventional theoretical formulas deliver. development of personality in psychology
