ABSTRACT:
Processing diversity signals includes receiving diversity signals at a number of antennas. The diversity signals have communicated information, and the antennas are associated with channel paths. A phase of at least one diversity signal is adjusted. The diversity signals are combined to form a combined signal. The combined signal is processed to yield the communicated information. A combined complex channel gain estimate is determined from the combined signal. An individual complex channel gain estimate is calculated for each antenna from the combined complex channel gain estimate. Phase adjustments associated with the channel paths are established according to individual complex channel gain estimates. The phase adjustments are applied to next diversity signals having next communicated information. The next diversity signals are processed to yield the next communicated information.
