Abstract :
In this paper we propose a wideband impulse modulated based system for indoor power line communications (PLC). Impulse modulation is combined with DS-CDMA to allow for user multiplexing. We describe the key system parameters and we focus on the receiver algorithms. The receiver operates in the frequency domain (FD). We describe various FD algorithms that include the capability of canceling the inter-code interference and the multiple access interference. Simulation results are reported for a proposed wide band statistical channel model.
