Patent ID: 8693964

Claim:
A method, comprising: applying one or more beamsteering matrices to one or more signals to produce a plurality of signals to be transmitted via multiple antennas; after applying the one or more beamsteering matrices to the one or more 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; determining relative signal energies based on the determined signal energies; adjusting, based on the determined relative signal energies, output power levels of the plurality of power amplifiers; after adjusting output power levels of the plurality of power amplifiers, determining whether output power levels of the plurality of power amplifiers should be kept at or near a same level; and in response to determining that output power levels of the plurality of power amplifiers should be kept at or near the same level, (i) disabling adjustment of output power levels of the plurality of power amplifiers, and (ii) setting output power levels of the plurality of power amplifiers at or near the same level.
