Apparatuses for a transmitter and a receiver (202) which enhance the performance of a system coherent demodulation by utilizing non-pilot sub- channels to enhance the accuracy of estimates of amplitude and phase noise inherent in the transmission channel. This enhancement is accomplished by utilizing the corrected received data on a fundamental channel to enhance a pilot channel estimate, which is subsequently utilized by a dot product modu le in demodulating a supplementary data channel.
