ABSTRACT:
A receiver and method are provided for receiving signals transmitted thereto from a transmitter during operation of a radio communication system. To synchronize the receiver with the transmitter, the receiver includes a delay lock loop circuit capable of receiving a pilot signal and a diversity signal transmitted from a plurality of transmit antennas and/or received by a plurality of receive antennas. The delay lock loop circuit is capable of calculating a first error signal based upon the pilot signal, and a second error signal based upon the diversity signal. The delay lock loop circuit is then capable of forming a combined error signal based upon the first and second error signals, and capable of synchronizing the receiver with the transmitter based upon the combined error signal.
