  • Method and device for nonlinear maximum likelihood sequence estimation by removing non-linear inter-symbol-interference (ISI) from a received signal
    Patent number: 6600794
    Abstract: Maximum Likelihood Sequence Estimation (MLSE) is performed on a received signal that is affected by non-linear distortion. In particular, a cleaned signal is produced by removing non-linear inter-symbol-interference (ISI) through a Volterra canceller which is a simplified structure with respect to a Volterra Equalizer. The latter only processes the non-linear distortion. Finally, a Viterbi Detector is used to process the cleaned signal in the manner of a linear signal, and to estimate appropriate metrics accordingly.
