Abstract:
1. An integrated circuit communication device configured for operation over a multi-pair transmission channel, the communication device comprising: a decoder circuit for receiving and decoding at least one intersymbol interference (ISI) compensated signal sample, and generating tentative decisions and a final decision; and a decision feedback equalizer coupled in feedback fashion to the decoder circuit, the decision feedback equalizer including a set of low-ordered coefficients and a set of high-ordered coefficients, the decision feedback equalizer generating a first portion of ISI compensation based on the tentative decisions and the high-ordered coefficients; and a convolution engine coupled to the decision feedback equalizer to receive values of the low-ordered coefficients, the convolution engine computing a set of pre-computed values representing a set of potential second ISI compensation portions.
