Dynamic bit-loading in pDSL communications systems

Abstract

This paper presents a dynamic discrete bit-loading algorithm for multicarrier pDSL communication links that utilize the indoor power line network. In order to confront the time varying behavior of power line transmission media, the proposed algorithm provides fast adaptive bit and power loading with reduced complexity using channel state information and a subchannel link-allocation profile. Numerical results based on simulated network loading scenarios demonstrate the performance and the complexity of the proposed method.
