ABSTRACT:
A method and system for implementing antenna verification in a closed loop transmit diversity system. The method includes the step of processing a received signal using a finger processors to generate a plurality of finger outputs. The mobile station is communicatively coupled to a base station. The method also includes the step of combining each of the finger outputs using a combiner to produce a plurality of intermediate results. The intermediate results are obtained prior to a final summation performed by the combiner. An antenna verification process is performed using the intermediate results, the intermediate results in the pre-slot FSM (feedback signaling message) calculation from an FSM encoder, and the pre-slot FSM from the FSM encoder to efficiently estimate the error of the FSM signal and obtain the correct channel estimation by keeping the weight factors generated in a mobile station and used in a base station consistent with each other, thereby reducing the effects of FSM error between the base station and the mobile station.
