A Rapid Serial Timing Acquisition Algorithm for Hybrid DS/FFH Packet Radio Communication

In this article, we propose a simple, reliable, and rapid serial timing acquisition algorithm for hybrid direct-sequence and fast frequency-hopping packet radio communication systems. The proposed algorithm is designed in both the frequency domain of frequency hopping and the pseudonoise code domain of direct sequence. We provide the performance analysis for our proposed algorithm and confirm its exactness by simulation. Compared with the conventional serial search algorithm, the proposed algorithm shows much faster acquisition time while obtaining similar performance.
