Abstract
A preferred timing recovery scheme is particularly suitable for a high speed digital data communication system that employs T-spaced equalization in the receiving device, where echo cancellation occurs after equalization. The timing recovery technique is based upon an analysis of the impulse response of the equalizer structure (e.g., a structure having a feedforward equalizer and a decision feedback equalizer). The filter tap coefficients of the equalizer elements are analyzed and the sampling phase is adjusted such that a cost function associated with the performance of the equalizer structure is substantially optimized. The sampling phase of the receiver is adjusted in response to a control signal generated as a result of the timing recovery techniques.
