发明名称 Symbol-based decision feedback equalizer (DFE) with maximum likelihood sequence estimation for wireless receivers under multipath channels
摘要 A maximum likelihood sequence estimator (MLSE) sub-receiver is disclosed, in one embodiment of the present invention and includes an MLSE equalizer device responsive to input data to generate equalized data. The input data is generated from transmitted data by wireless transmission. The MLSE equalizer device processes the input data to generate residual channel response using a known codebook and the residual channel response to generate an MLSE codebook. The MLSE sub-receiver further includes an MLSE decoder responsive to the equalized data and the MLSE codebook for processing to determine maximum likelihood between the equalized data and the MLSE codebook. The MLSE decoder uses the maximum likelihood for decoding the equalized data to generate a decoded transmitted data by mitigating the effects of multi-path communication channel due to wireless transmission of the transmitted data.
