Claim:
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, comprising: receiving information defining the at least two signals; 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 combinations of the at least two orthogonal frequency division multiplexed signals representing the same information which are each compatible with a radio frequency communication of the same information to a receiver according to a model of the receiver, within a radio frequency carrier modulated by a respective orthogonal frequency division multiplexed signal; analyzing the respectively different combinations 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 representations 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 defined waveform, and (c) information representing a respective combined waveform comprising a selected combination of the transformed information from each of the at least two orthogonal frequency division multiplexed signals, based on said selecting.
