DISTRIBUTED CONTROL OF POWER IN MULTIPOINT-TO-POINT ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING COMMUNICATION |
摘要 |
A method for an orthogonal frequency division multiplexing multipoint-to-point communications system is provided. The method includes establishing communication between a first remote unit of a plurality of remote units and a host unit, the plurality of remote units communicatively coupled to the host unit in a multipoint-to-point, multiple access configuration, 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, and receiving information from the host unit to adjust a carrier power for tones transmitted by the first of remote unit so that the tones are substantially orthogonal when received at the host unit.
