Power minimization for delivering integrated multimedia services over digital subscriber line

We study the problem of designing an efficient resource allocation scheme i n the application of providing integrated multimedia services over digital subscriber line. For a predefined quality of service (QoS) requirement and data throughput, me show that the transmitted power consumption can be redu ced by applying the parallel transmission framework previously proposed. Da ta streams are recognized as a set of layers with different data rate and b it error rate requirements. The characteristics of the telephone channel ca n be utilized to provide unequal error protection naturally and thus effici ently, Simulation results provide comparison of the proposed parallel trans mission framework to the existing schemes designed for general data, and de monstrate significant performance improvement, such as 0.5-2 dB power gain.
