Patent ID: 8442142

Claim:
A method for processing signals, the method comprising: in a transmitting station comprising a plurality of transmitting antennas: generating a plurality of transmit chain signals corresponding to said plurality of transmitting antennas based on a plurality of data stream signals; determining a per-antenna gain factor for each of said plurality of transmitting antennas based on one or more maximum per-antenna threshold levels and/or a maximum total-power threshold level; generating a plurality of transmitted signals based on said determined per-antenna gain factors and said plurality of transmit chain signals; determining a transmit chain power level for each of said plurality of transmit chain signals; selecting clipping antennas from said plurality of transmitting antennas, wherein for each of said clipping antennas, an amplified said transmit chain power level is greater than the corresponding maximum per-antenna threshold level; and determining a clipping per-antenna gain factor for each clipping antenna based on the corresponding maximum per-antenna threshold level and based on a ratio of the corresponding maximum per-antenna threshold level and a corresponding said transmit chain power level.
