Method and apparatus for performing directional re-scan of an adaptive antenna

An antenna for use with a receiver in a wireless communications system includes antenna elements for generating antenna patterns, and a first module for applying weights to a signal received at each of the antenna elements to generate a selected one of the antenna patterns. A second module detects t...

Zusammenfassung:An antenna for use with a receiver in a wireless communications system includes antenna elements for generating antenna patterns, and a first module for applying weights to a signal received at each of the antenna elements to generate a selected one of the antenna patterns. A second module detects the received signal at each of the antenna elements. A combiner combines the received signal detected at each of the antenna elements to produce a combined received signal for a selected antenna pattern. A third module determines a signal quality metric for the combined received signal at each selected antenna pattern. The first module is responsive to the determined signal quality metrics for adjusting the weights to generate a preferred antenna pattern.
