Patent ID: 8165543

Claim:
A method, comprising: applying one or more beamsteering matrices to a plurality of signals to be transmitted via multiple antennas; after applying the one or more beamsteering matrices to the plurality of signals, providing the plurality of signals to a plurality of power amplifiers coupled to the multiple antennas; determining signal energies for the plurality of signals provided to the plurality of power amplifiers; comparing one of the determined signal energies to each of one or more other determined signal energies; determining a maximum signal energy corresponding to one of the plurality of signals; determining one or more ratios, comprising, for each of the one or more other signals in the plurality of signals, determining a respective ratio of the signal energy of the other signal to the maximum signal energy; and controlling the plurality of power amplifiers via power amplifier control inputs to adjust output power levels of the plurality of power amplifiers, wherein adjusting output power levels comprises i) setting an output power level of a power amplifier corresponding to the maximum signal energy to a defined output power level, and ii) setting a corresponding output power level for each of one or more additional power amplifiers to a corresponding power level based on a corresponding determined ratio.
