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.
