Abstract

A powerline network physical layer that allows multiple nodes to communicate digital data at high speed, with low error rates, using electrical powerlines in a home or office is described. The physical layer provides multiple channels by using Frequency Division Multiplexing (FDM). Each FDM channel is independent and separately modulated to carry data using Differential Binary Phase Shift Keying (DBPSK) or Differential Quadrature Phase Shift Keying (DQPSK). The error rate on each FDM channel is monitored and the separate channel are used according to an error rate criterion. If a channel is presenting an error rate that is too high, the channel is either disabled, ignored, or reconfigured into a reduced-capacity mode that provides an acceptable error rate.
