Patent ID: 6999517

Claim:
A digital telemetry system having improved data rate and robustness, comprising: a data transmission cable having a first end and a second end, and capable of transmitting data on at least two propagation modes; a data source connected at the first end and having data transmission circuitry to generate data signals on the at least two propagation modes; a receiver connected to the second end whereon the receiver receives signals on a first and second of at least two propagation modes and having a processor connected to a storage medium storing instructions directing the processor to execute an adaptive far-end cross-talk cancellation logic for canceling cross-talk that occurs between the first and second propagation modes, wherein the adaptive far-end cross-talk cancellation logic comprises a first propagation mode cross-talk adjustment logic to direct the processor to receive samples on the first propagation mode and having a second propagation mode cross-talk adjustment logic to direct the processor to accept samples from the second propagation mode wherein the first propagation mode cross-talk adjustment logic directs the processor to adjust the samples on the first propagation mode by values that are a function of the samples of the second propagation mode; and further comprises instructions to cause the processor to determine a slice residual from the output of each of the first and second mode cross-talk adjustment logics; and update a cross-talk parameter from the slice residual.
