Patent ID: 7535969

Claim:
A method for transmitting a signal over a wireless channel, comprising: acquiring information representative of a state of the channel based upon an initial signal transmitted over the channel; acquiring information representative of a transmission mode of the signal; determining transmit power weighting values for the signal as a function of frequency based upon the state of the channel and the transmission mode of the signal, wherein the step of determining includes generating said transmit power weighting values and a plurality of transmit antenna spatial weights; weighting the signal with the transmit power weighting values thereby generating a weighted signal, wherein the transmit power weighting values and the plurality of transmit antenna spatial weights are jointly optimized via a global search; transmitting the weighted signal in accordance with the transmission mode, wherein the step of transmitting is performed through a plurality of antennas; and weighting said weighted signal transmitted through each of the plurality of antennas with one of a corresponding plurality of transmit antenna spatial weights.
