Adaptive Recovery Of A Doppler Shifted Mobile Communications Signal Using RLSAlgorithm

摘要

This paper studies the ability of the exponentially weighted RLS algorithm totrack a doppler shifted BPSK communications signal. This is modeled as a chirped ARI process in gaussian white noise. Expressions for the optimum Wiener filter, noise misadjustment, and lag misadjustment are shown. It is shown that as in the chirped sinusoid case the error can be written in terms of the forgetting rate
