  • Symbol-based decision feedback equalizer (DFE) optimal equalization method and apparatus with maximum likelihood sequence estimation for wireless receivers under multipath channels
    Patent number: 7266146
    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.
