Abstract

We consider the design of biorthogonal, as opposed to orthonormal, discrete multitone (DMT) systems supporting multiple services. The services may have differing quality of service (QoS) requirements, quantified by bit rate and symbol error rate specifications. Different users on the system can be potentially assigned different number of subchannels. Our goal is to minimize the transmitted power given the QoS specifications for the different users, subject to the knowledge of the channel and colored interference at the receiver input of the DMT system. We find an optimum bit loading scheme that distributes the bit rate transmitted across the various subchannels, the precise subchannels assigned to each user, and an optimum transceiver.
