Fast adapting fading channel equalizer

摘要

A receiver system for processing diversity channel signals to substantially eliminate future and past intersymbol interference (ISI) in received signals which have been transmitted through a time-varying frequency selective transmission medium. The system includes lattice filter means which provide forward error residual signals which are used for generating uncorrelated adaptive weighting signals which eliminate future ISI and decision feedback circuitry which provide uncorrelated adaptive weighting signals which eliminate past ISI.
