Abstract:
1. A method for a remote unit of an orthogonal frequency division multiplexing multipoint-to-point communications system, the method comprising: receiving an address code assignment at a first remote unit of a plurality of remote units from a host unit, the plurality of remote units communicatively coupled to the host unit in a multipoint-to-point configuration; communicating with the host unit using the address code, wherein the address code is unique among the plurality of remote units; and transmitting up to a plurality of tones from the first remote unit, the up to a plurality of tones modulated with upstream information using orthogonal frequency division multiplexing, wherein the up to a plurality of tones are configured to combine with tones from other remote units of the plurality of remote units to a unified orthogonal frequency division multiplexing waveform at the host unit.
