A recursive formulation for quadratic detection on Rayleigh fadingchannels

摘要

We address the problem of optimal detection of a random signaltransmitted over a time-varying frequency-selective correlated Rayleighfading channel. We present a general recursive solution which may beoperated at full complexity to provide optimal detection or at reducedcomplexity, using per-survivor processing (PSP) techniques, to yield asuboptimal receiver
