跳频异步组网捕获新技术研究

Research on New Technique of Frequency Hopping Asynchronous Networking

由于跳频异步组网使用同一频率集,跳频异步组网的用户在入网捕获时会受到多址效应的影响。在详细分析了现有跳频组网的方式、多址效应对捕获的影响、传统捕获方法的不足的基础上,提出了跳频异步组网捕获的新算法,很好的解决了用户入网捕获时受多址效应影响的难点问题。通过对比实验,证明了这个新方法的有效性和实用性,为跳频组网系统的建设提供了新思路和新方法。

Because frequency hopping asynchronous networking uses the same frequency-set, the user is influenced by the multiple access effect when acquiring. The paper describes two modes of frequency hopping networking, multiple access effect on acquisition and the deficiency of tradition acquisition technique. The new technique of multiple access effect acquisition based on frequency hopping asynchronous networking solves the influence of multiple access effect on user when acquiring. The comparison experiment results prove the validity and practicability of this new method. The new technique offers the new thoughts and methods for frequency hopping asynchronous networking system.
