Abstract

An adaptive transmit equalizer for equalizing digital symbols to be transmitted over a communications channel includes a transmit filter having an associated register for storing at least one filter coefficient. A tuning engine generates performance metric values based on digital symbols received through the communications channel. The tuning engine is configured to identify at least one filter coefficient based on the performance metric values using a simplex algorithm. The tuning engine is configured to communicate the at least one updated filter coefficient to the transmit filter for storage in the register.
