Validating Jakes model in Rayleigh Fading channels

WebDoppler effect in physics is defined as the increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move towards (or away from) each other. Waves emitted by a source travelling towards an observer get compressed. In contrast, waves emitted by a source travelling away from an observer get stretched out. WebWe derive methods for asymptotic maximum likelihood (ML) estimation of Jakes' Doppler power spectrum parameters from complex noisy estimates of the fading channel.
