Novel fast acquisition algorithm for DS/FH system

Based on differential correlation technique, novel fast acquisition algorithm is developed for hybrid direct sequence and frequency hopping (DS/FH) system. Specifically, by using differential correlation for PN code phase and parallel searching for frequency, the fast acquisition is realized. Furthermore, in terms of acquisition time and hardware resources consumption, the proposed differential correlation acquisition method is compared with the conventional waiting self synchronization acquisition method and frequency parallel searching acquisition method. Analytical and simulation results reveal that the proposed algorithm can be used in DS/FH system.
