Adaptive filter with coefficient determination based on output of real time clock

摘要

A transceiver comprises a transmitter and a receiver. At least one of the transmitter and the receiver comprises an adaptive filer. One or more coefficients of the adaptive filter are determined based at least in part on an output of a real time clock. The adaptive filter may comprise a coefficient update engine and a memory for storing a plurality of sets of adaptive filter coefficients in association with respective time indicators derived from the output of the real time clock, with the coefficient update engine being configured to determine a particular one of the sets of filter coefficients for use by the adaptive filter based at least in part on at least a subset of the time indicators. The time indicators may comprise respective time stamps generated based on the output of the real time clock at respective times at which the corresponding sets of coefficients are determined.
