ABSTRACT:
A method is provided for determining the modulation sequence of the downlink synchronization codes. The method comprises: the method comprises a three step process: step one is to measure the phase of the downlink synchronization code. Step two is to generate an accurate of the phase of the downlink synchronization code by removing the frequency drift effect, step three is to determine whether the sequence S1or S2is finally detected. The method allows for high accuracy to be achieved for determination of the modulation sequence of the downlink synchronization codes.
