Abstract

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 steadily. Thus, a solution is presented based on the classic Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) to solve this problem. Firstly, a mathematic model for recognition process is built by Markov chains. Secondly, TOPSIS is employed to make analysis and suggestions to the recognition strategies. Results show that the presented mothed can shorten the synchronization time, ensure the reliability of the synchronization systems, and achieve an optimal effect in frequency hopping capture confirmation process.
