ABSTRACT:
A maximum likelihood sequence estimator (MLSE) equalizer device being included in an MLSE sub-receiver includes a feedforward circuit responsive to input data for processing the same to generate feedforward circuit output, said input data being generated from transmitted data being transmitted by wireless transmission, in accordance with an embodiment of the present invention. The MLSE equalizer device further includes a feedback circuit responsive to said input data for processing the same to generate feedback circuit output. The MLSE equalizer device further includes 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 MLSE sub-receiver for decoding said equalized data to generate decoded transmitted data by mitigating the effects of multi-path communication channel due to wireless transmission of said transmitted data.
