基于淘汰判决的跳频同步捕获方案设计

跳频通信同步捕获方案中,串行自同步捕获方案与并行自同步捕获方案是目前应用最广的同步捕获方案,但是串行捕获方案同步捕获时间较长,并行捕获方案系统太复杂,对此提出了基于淘汰判决的同步捕获方案。从捕获时间、抗干扰性能以及系统复杂度3个方面评价了捕获方案的性能。实验结果表明,基于淘汰判决的捕获方案,在保证抗干扰性能与系统复杂度的同时,捕获时间约为串行自同步捕获方案的1/5。

Design of Frequency Hopping Synchronization Acquisition Scheme Based on Elimination Decision

Among the synchronous acquisition schemes of frequency hopping communication,the serial self-synchronous acquisition scheme and the parallel self-synchronous acquisition scheme are the most widely used ones at present,but the synchronous acquisition time of the serial acquisition scheme is longer,and the parallel acquisition scheme system is too complex.A synchronous acquisition scheme based on elimination decision is proposed.The acquisition time,anti-jamming performance and system complexity are evaluated.The experimental results show that the acquisition scheme based on elimination decision guarantees good anti-jamming performance and relatively low system complexity,while the acquisition time is about 1/5 of the serial self-synchronization acquisition scheme’s acquisition time.
