Abstract:
1. A method, comprising: determining a ratio of a transmitter gain to a receiver gain for a first of a transmit/receive chain pair of a plurality of transmit/receive chain pairs of a first wireless device; adjusting a ratio of transmitter gain to receiver gain for at least a second transmit/receive chain pair of the plurality of transmit/receive chain pairs to be substantially equal to the ratio of the transmitter gain to the receive gain for the first transmit/receive chain pair; determining a beamforming matrix for transmission from the first device to the second device; and transmitting to the second device at least one data stream using at least two antennas coupled to corresponding transmit/receive chain pairs having a ratio of transmitter gain to receiver gain that is substantially equal to the ratio of the transmitter gain to the receive gain for the first transmit/receive chain pair.
