Abstract:
1. A maximum likelihood sequence estimator (MLSE) equalizer device being included in an MLSE sub-receiver comprising: a feedforward circuit responsive to input data, said input data including a preamble portion, a header portion and a main data portion, for processing the input data to generate a feedforward circuit output, said input data being generated from transmitted data being transmitted by wireless transmission; a feedback circuit responsive to said input data to generate a feedback circuit output, said feedback circuit for processing said preamble portion to generate a feedback circuit output using feedback filter coefficients b an equalizer training module responsive to said feedforward circuit output and said feedback circuit output for training said MLSE equalizer device by minimizing the difference between said feedforward circuit output and said feedback circuit output, said MLSE equalizer device being trained to generate equalized data, said equalizer training module for training said MLSE equalizer device by adapting said feedback filter coefficients b
