Frequency Hopping Synchronization Strategy

Frequency hopping is one of the classic examples of spread-spectrum communications. This paper is about the study of the strategy of the synchronous recognition process. In other words, the topic is in which condition the hopping frequency in the receiver and transmitter can be identified. From the theoretical point of view, the more uniform frequency between the transmitter and the receiver, the more probability that the process can be accurately judged that the frequency has been synchronized. However, in practical situations such as military communications, systems always have higher requirements for the time of the process of the frequency hopping synchronization, so the recognition time and the recognition accuracy is a set of contradictions in the process. If taking other details into consideration, the selection of recognition strategy is a comprehensive evaluation and decision-making in mathematics modeling. Firstly, we use Markov chain to analyze the recognition process with mathematical modeling. Secondly, we use classic Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) and gray correlation method to make analysis and suggestions to the recognition strategy. The research has a great significance for hopping frequency synchronization.
