ClariPhy Communications, Fenwick & West, July 7, 2015: US09077572 (2 worldwide citation)

A receiver applies a calibration method to compensate for skew between input channels. The receiver skew is estimated by observing the coefficients of an adaptive equalizer which adjusts the coefficients based on time-varying properties of the multi-channel input signal. The receiver skew is compens ...
