Abstract
In a communication system that utilizes DMT technology to couple a primary site (102) to a plurality of secondary sites (104-108), the primary site (102) and each of the secondary sites (104-108) includes a DMT receiver. Such a DMT receiver includes a discrete multi-tone decoder that receives a time domain discrete multi-tone symbol and produces an ordered data stream based on bit loading information and a data de-formatter, operably coupled to the discrete multi-tone decoder, wherein the data de-formatter receives the ordered data stream and produces a recovered data stream based on carrier channel allocation information.
