Abstract
We consider the design of optimum discrete multitone (DMT) systems supporting multiple services with potentially differing quality of service (QoS) requirements. With the knowledge of channel and colored interference at the receiver input of the DMT system, our goal is to minimize the transmitted power while holding QoS specifications for different users. With redundancy in the form of a cyclic prefix, an optimum bit loading scheme, subchannel assigning scheme and transceiver design are found for DMT systems. As with our previous study involving zero padding redundancy, the key conclusions are: (i) the optimum transceiver is unaffected by changing service characteristics, and depends only on the channel and interference conditions; (ii) the QoS requirements, the number of users and the number of subchannels assigned to the different users only affect bitloading and subchannel assignment.
