Synchronization Design of Frequency-Hopping Communication System

Frequency hopping is one of the most classic examples of spread-spectrum communications. This paper is about the study of the strategy of the synchronous process. Modern frequency hopping systems generally use the sliding correlation scheme and the matched filter scheme which have the best anti-jamming performance. However, the sliding correlation scheme converges too slowly while the matched filter scheme occupies too much hardware. An improved acquisition scheme is developed which reduces the acquisition time, has excellent anti-jamming ability and limits the system complexity. The improved scheme not only keeps the best anti-jamming performance and an acquisition speed almost as fast as the classical matched filter scheme acquisition, but also has a simple structure which is comparable to the classical sliding correlation acquisition.
