ABSTRACT:
A bidirectional communication system is provided. In one embodiment, a system comprises a plurality of remote units; a multipoint-to-point host unit communicatively coupled with a plurality of remote units in a multi-point to point configuration, the multipoint-to-point host unit including a multi-carrier modem configured to communicate with the plurality of remote units via an orthogonal frequency division multiplexing waveform; wherein the multipoint-to-point host unit is configured to estimate a round trip path delay correction associated with at least one of the plurality of remote units; and wherein the multipoint-to-point host unit is configured to adjust the round trip path delay associated with the at least one of the plurality of remote units.
