METHODS AND CIRCUITS FOR ADJUSTING PARAMETERS OF A TRANSCEIVER

摘要

Methods and circuits for analyzing a signal and adjusting parameters of an equalizer for a signal. The signal is received at a receiver over a channel wherein the signal has a wave form. The signal is equalized at an equalizer using an adjustable parameter for the equalization. Data points from the signal are sampled between upper and lower limits of a threshold at an error sampler. A performance metric of the signal is computed based on a statistical density of the data points from the signal between the upper and lower limits of the threshold.
