System and method for controlling combined radio signals

摘要

A method for controlling a combined waveform, representing a combination of at least two signals having orthogonal frequency multiplexed signal components, comprising: receiving information defining the at least two signals; transforming the information defining each signal to a representation having orthogonal frequency multiplexed signal components, such that at least one signal has at least two alternate representations of the same information, and combining the transformed information using the at least two alternate representations, in at least two different ways, to define respectively different combinations; analyzing the respectively different combinations with respect to at least one criterion; and outputting a respective combined waveform or information defining the waveform, representing a selected combination of the transformed information from each of the at least two signals selected based on the analysis.

1. A method for controlling a combined waveform, representing a combination of at least two orthogonal frequency division multiplexed signals having orthogonal frequency signal components which occupy different frequency bands, comprising:
receiving information defining the at least two orthogonal frequency division multiplexed signals which occupy different frequency bands; transforming the information defining each respective orthogonal frequency division multiplexed signal to at least one representation having orthogonal frequency signal components, the information defining at least one of the respective orthogonal frequency division multiplexed signals being transformed into at least two alternate representations, each representation being a orthogonal frequency division multiplexed having different orthogonal frequency signal components representing the same information; combining the transformed representation of the information of the at least two orthogonal frequency division multiplexed signals each having orthogonal frequency signal components, using the at least two alternate representations, in at least two different ways, to define respectively different combined waveforms of the at least two orthogonal frequency division multiplexed signals which occupy different frequency bands and are not mutually orthogonal with respect to each other, each of the at least two alternate representations representing the same information; analyzing the respectively different combined waveforms representing the same information with respect to at least one criterion dependent on the combination; selecting a respective one of the at least two alternate respectively different combined waveforms for inclusion in a combination based on said analyzing and outputting at least one of: (a) information identifying a respective combined waveform, (b) information defining the respective combined waveform, and (c) information representing a respective combined waveform, based on said selecting.
