Abstract
The n symbols of a codeword of length n are transmitted on n separate channels or frequencies simultaneously. A receiver includes n equalizers that are adapted to receive information from respective ones of the n channels. The outputs of the n equalizers are applied to n inputs of an error correcting decoder which produces the original version of the transmitted codeword. The n equalizers include n feedforward and n feedback transversal filters whose taps are updated by n tap update processors in accordance with a Kalman algorithm, or the like, once each codeword time. The feedforward registers contain successively received signal samples of each of the n channels while the n decision feedback registers contain successively corrected symbols generated at each of the n decoder outputs.
