Patent ID: 8838051

Claim:
A method comprising: generating a plurality of beamforming steering matrices associated with a plurality of subcarriers of an RF signal received at a transceiver unit; applying the plurality of beamforming steering matrices to the subcarriers of the RF signal based on the beamforming steering matrices associated with each transmit chain of a plurality of transmit chains of the transceiver unit; calculating a maximum transmit power associated with each of the plurality of transmit chains; for each of the plurality of transmit chains, calculating a sum of a square of each element of each beamforming steering matrix associated with the transmit chain, in response to said applying the plurality of beamforming steering matrices to the subcarriers of the RF signal; dividing the sum by a number of streams to be transmitted by the transceiver unit to yield an average change in transmit power associated with the transmit chain; calculating a square root of a ratio between the maximum transmit power associated with the transmit chain and the average change in the transmit power associated with the transmit chain to yield a power scaling factor for the transmit chain; and applying each power scaling factor to a corresponding transmit chain of the plurality of transmit chains to set the transmit power associated with each transmit chain to approximately the maximum transmit power associated with the transmit chain.
