Abstract

There is disclosed an equalizer or a receiver including an equalizer which has means to factor detected symbols transmitted over a transmission channel into a magnitude portion and a repetitive phase portion. The receiver further has means to generate modified tap weights by multiplying the repetitive phase portion by tap weights representative of the channel. Modified tap weights are generated by multiplying the repetitive phase portion by tap weights representative of the channel. The modified tap weights are convolved with bits of possible states to generate possible transmitted symbols. A maximum likelihood sequence estimation is performed on the possible transmitted symbols comparing each possible transmitted symbol to a received symbol to generate an MLSE detected symbol. The detected symbol is multiplied by a rotating vector to generate a decoded symbol. In an alternate embodiment, a received symbol from the sequence of received symbols is multiplied by a rotating vector prior to performing the maximum likelihood sequence estimation.
