Patent ID: 8203975

Claim:
A transceiver, comprising: an analog front end (AFE) device that receives a first analog receive signal and that generates a digital receive signal and a second analog receive signal; first, second, third, and fourth transmitters that generate respective digital transmit signals and respective analog transmit signals; a digital signal processor (DSP) that receives said digital receive signal and said digital transmit signals and that generates a shared error control signal and first, second, third, and fourth individual error control signals; an echo canceller system that generates an estimated echo signal based on said second analog receive signal and said analog transmit signal from said first transmitter during a first mode and based on said shared error control signal, said first individual error control signal, and said analog transmit signal from said first transmitter during a second mode; and first, second, and third near-end crosstalk (NEXT) canceller systems that generate first, second, and third estimated NEXT signals, respectively, each based on said second analog receive signal and respective ones of said analog transmit signals from said second, third, and fourth transmitters during said first mode and each based on said shared error control signal, respective ones of said second, third, and fourth individual error control signals, and said respective ones of said analog transmit signals from said second, third, and fourth transmitters during said second mode.
