摘要： Systems for multiple use subchannels are provided. In one embodiment, a bidirectional communication system comprises: a first remote unit for communicating with a host using OFDM, the host communicatively coupled to a plurality of remote units in a multipoint-to-point configuration. The first remote unit is configured to transmit up to a plurality of tones, the up to a plurality of tones modulated with upstream information using OFDM, the first remote unit including a modulator for modulating the up to a plurality of tones using OFDM. The modulator is configured to adjust a carrier frequency and timing of the plurality of tones such that when any tones are transmitted from the first remote unit and at least one other remote unit, the orthogonality of the tones when received at the host unit is improved. Both control data and payload data are transmitted on a first tone of the plurality of tones.

In one embodiment, a multi-carrier modem comprises: a receiver configured to de-modulate symbols from at least one of a plurality of spectrally overlapping carrier signals to produce a receiver output; a transmitter configured to modulate symbols onto at least one of a plurality of the spectrally overlapping carrier signals; a processor coupled to the transmitter, wherein the processor outputs data for transmission by the transmitter, wherein the processor applies an inverse Fourier transform to the data transmitted by the transmitter; the processor coupled to the receiver, wherein the processor applies a Fourier transform to the receiver output; and a controller programmed to instruct the transmitter to transmit at least one symbol representing a request for bandwidth allocation on a first carrier; wherein the controller is further programmed to determine when a collision has occurred on the first carrier.
