Abstract
A system for wireless communication between a base station 30 and one or more remote stations 32 and 34 wherein the beam pattern of the receiving antenna 50-52 can be adaptively formed to track a desired signal. A series of weights is applied, one to each output of the elements of the receiving antenna and the weighted output summed to form the antenna output. The weights are adaptively modified so as to focus the beam in the direction of one of many signals which may be present in the data received by the antenna. A least-square-error process is used to identify if the signal beamed on is the desired signal. If such is not the case, the weights are modified to null out the earlier signal and to focus the pattern on another signal.
