A reduced complexity viterbi equalizer used in conjunction with a pulse shaping method

• The complexity of the Viterbi algorithm can be reduced by linear pre-equalization. We introduce a linear preprocessor using the weighted least squares filtering of [10]. The geometric technique of L.Barbosa [3] is evoked for analytical representation of the complexity reduction by pre-equalization, and for evaluation of error performance. We give results on the bit error rate of the WLS preprocessor and of the linear preprocessor of Falconer and Magee [6].
