摘要： A system for time delay estimation in a discrete time processing system includes a cross correlator that performs cross correlation on a first signal and a second signal, and provides a cross correlated output signals indicative thereof. A lag smoother receives the cross correlated output signals, and provides lag smoothed output signals indicative thereof. A select logic module selects a pre-defined number of signal values from a respective set indicative of the lag smoothed output signals to compute the time delay estimation associated with the first and second signals.

摘要： The problem of inefficient channel impulse-response processing is addressed by processing different parts of a channel impulse response to accurately locate channel taps, and to generate more than one set of equalization coefficients. This allows the most-suited equalization coefficient to be selected based on a selection criterion.
