Abstract
An adaptive diversity receiver for digital communications provides a plurality of transversal filters disposed in front of a linear combiner for each of a plurality of diverse channels. The tap gains of each of the transversal filters are updated to estimate the sampled values of the channel impulse response for each diverse channel as a function of the detected data output, rather than providing tap gain updating as a function of the data error signal. In this manner, each transversal filter operates as an adaptive match filter for the corresponding diversity channel.
