Abstract

There has been a considerable interest in the application of multicarrier modulation techniques to high speed data transmission recently. In this talk, we develop optimal transceiver for discrete multitone (DMT) modulation with zero suffix for the two cases, with and without pre-detection equalizer. The optimal transceiver consists of maximum likelihood pre-processor followed by optimal demodulator. The optimality criterion under which the demodulator is derived is the maximization of bit rate for a given average transmitted energy and specified symbol error probability in all the subchannels. The development for the pre-detection equalizer case also applies to the case when the channel noise is colored.
