【 摘 要 】

In frequency hopping communication systems, synchronization of frequency hopping sequences is a prerequisite for ensuring normal communication. In this paper, a rapid frequency hopping synchronization capture method is designed based on MSK modulation. A method of solving the constant false alarm threshold is given, and a set of high performance synchronization codes are selected. We assessed the effectiveness of the proposed process by simulation based on MATLAB and Vivado, and it can complete rapid synchronous capture in the frequency hopping communication system.
