An equal gain composite beamforming technique which constrains that the
power of the signal output by each antenna is the same, and is equal to
the total power of the transmit signal divided by the number N of
transmit antennas from which the signal is to be transmitted. By reducing
output power requirements for each power amplifier, the silicon area of
the power amplifiers are reduced by as much as N times (where N is equal
to the number of transmit antennas) relative to a non-equal gain CBF.
