Patent ID: 7345988

Claim:
A communications system for minimizing crosstalk in high speed signaling links within a communications system, the communications system comprising: a plurality of transmitters, each transmitter including transmit signal level adjustment circuitry to adjustable transmit signal level of the transmitter; and a plurality of receivers, each receiver includes circuitry to sense a received signal level and, in response thereto, generate a control signal, wherein each receiver is coupled to an associated transmitter; wherein each transmitter, in response to the control signal from the associated receiver, adjusts the transmit signal level to cause a received level sensing signal to correspond to a desired received signal level; wherein each receiver is configured to generate a sum data value of the sign of an error value times the sign of data values over a sequence of data symbols received by the receiver; and wherein the control signal is configured to command an associated transmitter to adjust the signal level based upon the sign of the sum data value generated in the receiver.
