Abstract
A bidirectional communication system is provided. In one embodiment, a system comprises a host unit to communicate with a plurality of remote units using orthogonal frequency division multiplexing (OFDM), the plurality of remote units communicatively coupled to the host unit in a multipoint-to-point configuration; and wherein the host unit is configured to adjust a round trip path delay associated with at least one of the plurality of remote units.
