Patent ID: 7561633

Claim:
A communications transceiver, comprising: i. N transmitters; ii. An N-input N-output receiver, comprising: (a) A multi-input multi-output (MIMO) canceller filter, with N inputs and N outputs, for canceling echo and near end cross talk (NEXT), coupled to the outputs of the N transmitters, comprising a plurality of feed-forward digital filters with self and cross connections; (b) A MIMO feed-forward equalizer (FFE) containing a plurality of digital filters with self and cross connections; (c) A MIMO decision-feedback equalizer (DFE), containing a plurality of digital filters with self and cross connections, used for far-end cross talk processing; (d) N decision devices or slicers, whose inputs are controlled by the outputs of the MIMO canceller filter, MIMO feed-forward equalizer, and MIMO decision-feedback equalizer, whose outputs are coupled to the MIMO decision-feedback equalizer, and are the outputs of the receiver; (e) Generation of N first error signals by subtracting the inputs of the N slicers from their corresponding outputs, used to adapt the coefficients of the digital filters.
