Abstract:
A method for establishing optimal weights for a plurality of elements cooperating to form a subscriber unit antenna in a wireless communications system, in response to the occurrence of an event on the wireless communications system, said method comprising the steps of:(a) applying weights to the signal received at each of the plurality of elements; (b) detecting a received pilot signal at each of the plurality of antenna elements; (c) combining the received pilot signal detected at each of the plurality of antenna elements to produce a combined received pilot signal; (d) determining a signal quality metric for the combined received pilot signal at the current directional angle, as determined by the weights, of the subscriber unit antenna; (e) adjusting the weights of at least one of the plurality of antenna elements to establish a different directional angle for the subscriber unit antenna; (f) repeating steps (b) through (e); (g) selecting the optimal signal quality metric of the combined received pilot signal; and (h) adjusting the weights for the plurality of antenna elements to achieve the directional angle associated with the selected optimal signal quality metric.
