Abstract :
The performance of per-survivor processing (PSP) algorithms with stochastic gradient estimators is investigated for frequency-selective channels and array measurements. The focus is on the degree to which the underlying channel structure can be reliably exploited by such algorithms in tracking the time-varying channel and detecting the data
