Claim:
1. A method of using a plurality of antennas for a wireless communication, the method comprising: determining a plurality of complex weights based on a plurality of channel impulse responses, wherein each channel impulse response relates a first signal transmitted from one of the plurality of antennas to a second signal received by a receive antenna at a plurality of frequencies, wherein the plurality of complex weights are determined such that a composite channel response at the receive antenna is substantially flat over the plurality of frequencies, wherein the composite channel response is equal to a sum of a plurality of products associated with the plurality of antennas, and wherein each of the plurality of products is a product of a complex weight and a corresponding channel impulse response for one of the plurality of antennas; applying each complex weight to a signal to be transmitted by a corresponding one of the antennas to form a plurality of weighted signals; and transmitting each of the plurality of weighted signals from the corresponding one of the plurality of antennas.
