Research on Frequency Hopping Synchronization Strategies based on TOPSIS Method
Journal of Physics: Conference Series, 2019 The synchronization of hopping frequency is a key step in frequency hopping communication systems. During system synchronization, the contradiction emerges between synchronization duration and credibility in the capture confirmation process after frequency acquisition, which make it difficult for the system to establish synchronization quickly and ...
