1. A receiver system for processing signals received in a plurality of diversity channels, said receiver system comprising adaptive matched filter means responsive to said received signals for providing a diversity combined received signal; means responsive to said diversity combined received signal for adaptively correcting for intersymbol interference in said received diversity signal, said adaptively correcting means including adaptive lattice filter means responsive to said diversity combined received signal for providing a plurality of error residual signals which form an uncorrelated set of signals, said lattice filter means using said uncorrelated error residual signals for producing an adaptively corrected signal in which future intersymbol interference and past intersymbol interference are substantially eliminated; and decision detector means responsive to said adaptively correcting means for producing a quantized data output signal.
