    摘要: A method for training of a non-updated decision feedback equalizer is provided. The method comprising the steps of: providing a sequence of frames adapted to be received by a receiver; provide a sequence of synchronization frames interposed between a predetermined number of frames; and using at least part of the sequence of synchronization frames to train a decision feedback equalizer (DFE), thereby speeding up system convergence or making system convergence possible.

    摘要: A decision feedback equalizer is configured to equalize an input signal to generate a recovered output signal. Linear feed-forward filter circuitry is configured to provide a linearly filtered output signal based on the input signal. Composite trellis decoder circuitry configured to process a combined signal that is based on a combination of at least the linearly feed-forward filtered output signal and on output of linear or non-linear feedback filter circuitry, in accordance with state metrics generated by processing a composite trellis diagram relative to the combined signal, to provide a trellis-decoded output signal as input to the linear or non-linear feedback filter circuitry. The composite trellis decoder circuitry is further configured to provide a particular phase output of the combined signal, based on the state metrics, as the decoded output signal.
