Analysis and research of synchronization technique for frequency-hopping communication systems

The synchronization is one of the key techniques in frequency hopping communication system. In this paper, a new synchronization scheme for high-speed frequency hopping is analyzed after analyzing synchronization in conventional frequency hopping communication system. Based on the method combined synchronization-head with time of day (TOD), the synchronization information is carried by slow-hopped pattern, and the corresponding message is carried by fast-hopped pattern, which overcomes the difficulty of correlation code transmission in fast frequency hopping. This paper mainly studies the frame of synchronization head,the synchronization of FH pattern. The performance of synchronization is analyzed and the simulation is completed by using Matlab7.0. The performance of synchronization shows that the scheme has the advantages of short synchronization time, higher probability of capture and lower false probability.
