ABSTRACT:
In a diversity reception communication system (200), a method is provided for recovering data symbols (213) from a transmitted signal. Multiple signals representing the transmitted signal are received via corresponding multiple reception paths (201, 202). For each reception path, values are determined for noise (206), channel quality (207), and for a weighting factor (209) as a function of the channel quality. The signals are processed using diversity combining (212) which includes the weighting factor (209) for each reception path, to provide a resultant signal that more likely represents the transmitted signal than any of the received signals alone. The data symbols (213) are recovered from the resultant signal.
