ABSTRACT:
A receiver chain (53) for use in a wireless communication system includes a compact, highly correlated, multi-element antenna. The multiple antenna elements (34) and (35) are configured to receive a signal from at least one base station. The highly correlated signals output from the antenna elements (34and35) are optimally combined in a controller (55) using a set of weighting factors. The set of weighting factors for each base station signal is determined in response to the spatial signatures of the received signals.
