ACQUISITION OF GATED PILOT IN CDMA SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide systems and techniques which enable a gated pilot signal to be acquired faster by checking neighbor pilot signals of a target pilot signal.

SOLUTION: A subscriber station may frequency-lock onto a wrong pilot burst because a partial correlation exists between the wrong pilot burst and an adjacent pilot burst. Comparing the strength of the target pilot signal with the strength of neighbor 10 pilot signals enables the selection of the strongest pilot signal before the timely process of frequency locking and demodulation are initiated. Grouping pilot signals with the same symbol sequence and a pseudo-random noise increment apart enables quick acquisition of a gated pilot signal.
