A new algorithm for fast acquisition for direct-sequence spread-spectrum systems

직접시퀀스 확산대역 시스템의 빠른 포착을 위한 새로운 알고리듬

We have proposed a new fast serial serch algorithm and a receiver for direct-sequence spead-spectrum acquisition systems and analyzed its perfoemance. This algorithm achieves faster acquisition by more than two times that of existing algorithm. We have derived equations of the mean acquistion time by using moment generating function and direct approach, and presented numerical results.
