Abstract:
A receiver includes a feed-forward equalizer, a first detector, a jitter estimation circuit, and a jitter mitigation circuit. The feed-forward equalizer is configured to equalize channel gain of digitized samples of a received signal and to output equalized samples. The first detector is configured to detect symbols in the equalized samples. The jitter estimation circuit is configured to estimate jitter in the equalized samples by estimating a deviation in periodicity between pairs of the equalized samples. The jitter mitigation circuit comprises a linearized FIR filter configured to receive an input including the equalized samples or the detected symbols and to compensate inter symbol interference in the equalized samples due to the jitter as a function of the estimated jitter and an estimate of the inter symbol interference.
