Abstract
Apparatus for identifying (78) a signal point of a receive constellation corresponding to an extracted symbol of a train of symbols of a modulated communication signal and for adjusting (88) the signal point to a new position of the receive constellation based on the position of the extracted symbol in relation to the current position of the signal point. The new position of the identified signal point becomes part of the receive constellation for processing at least one subsequently extracted symbol of the communication signal. In addition, apparatus is provided for adjusting (120) equalizing coefficients of an equalizer (76) based on factors including an equalized extracted symbol, the identified signal point, corresponding extracted symbols of the equalizer, and an adaptive gain factor.
