Abstract

Modern Fast Frequency Hopping (FFH) systems generally use the sliding correlation scheme and the matched filter scheme which both have the best anti-jamming performance. However, the sliding correlation scheme converges too slowly and the matched filter scheme occupies too much hardware resource. An improved acquisition method was developed. Compared with the former two methods, the new method which has the same synchronization probability and false alarm probability, decreases the mean acquisition time and reduces the hardware complexity. Simulations show that, the improved scheme which keeps the best anti-jamming performance, has a simpler structure than the classical sliding correlation acquisition. Meanwhile, the acquisition speed of the new method is almost as fast as the classical matched filter acquisition.
