A system and method for training a plurality of equalizers to recognize a plurality of symbols in a received signal, the plurality of equalizers deriving intermediate symbols from the received signal as a function of at least one filter coefficient, the system including 1) a phase detection circuit that determines a phase error between at least one intermediate symbol and at least one symbol in a predetermined constellation of symbols, and 2) a coefficient modification circuit that modifies at least one filter coefficient of the plurality of equalizers as a function of the phase error to cause the at least one intermediate symbol to converge toward a symbol in the predetermined constellation of symbols as the phase error approaches zero, the intermediate symbols being substantially equal to the predetermined constellation of symbols when the phase error is equal to zero. The system or method may be employed in a modulator/demodulator (MODEM) to enhance the communication of digital data through an analog transmission medium.
