Frequency Hopping Synchronization Method and Simulation in VHF Channel

Synchronization is one of the key techniques to frequency-hopping (FH) communication. Based on the requests of synchronization for a VHF FH communication system, this paper puts forward a synchronization scheme, which is achieved accurately and rapidly by using a Self synchronization-head method combined correlation code with time of day (TOD), which contains synchronous interval information. This paper mainly studies frame format of FH Synchronization, synchronization of FH pattern, FH tracking, and so on. The performance of synchronization shows that the time of initial synchronization in FH communication system meets the requirements. In addition, simulation under the Gauss White Noise channel and Tactical channel indicates that the system has high capture probability.
