摘要:
A method of initializing a receiver is performed during an initialization mode. Timing offset values for a timing recovery circuit are repeatedly selected. For each selected timing offset value, timing recovery is performed using the timing offset value and groups of weights for a decision feedback equalizer are repeatedly selected. Each selected group of weights is used to perform blind decision feedback equalization. For each selected group of weights, a metric indicating data reception quality is computed. A timing offset value and a group of weights are chosen based on the computed metrics.
