ABSTRACT:
An embedded pattern-based adaptive equalizer coefficient updating mechanism updates weighting coefficients of an adaptive equalizer in accordance with an error or differential signal obtained by processing the distorted version of a known signal pattern, that is repetitively distributed among information signals contained within the electrical communication signal output from the equalizer, with a copy of the known signal pattern. No dedicated ‘training sequence’ communication with the transmitter is required, so that the coefficient update mechanism does not impact the operation or bandwidth availability of the channel.
