摘要:
针对传统跳频通信接收机单通道串行接收捕获时间长,多通道并行接收系统复杂度高的问题,提出了双通道跳频通信系统同步捕获方法。该方法将同步字头法与并行捕获相结合,利用同步过程中的载波频率与被调制时间信息共同确定频率跳变时间,在两个接收通道上进行并行捕获,缩短同步时间,提高同步的隐蔽性和抗干扰能力。仿真结果表明,相比单通道捕获,所提出的双通道同步捕获方法在捕获概率基本不变的情况下,初始同步时间缩短为原来的1/2,有效利用了接收机的双通道资源。
Abstract:
Aiming at the problems that the acquisition time of single-channel serial receiver is long and the complexity of multi-channel parallel receiver system is high in frequency hopping communication receiver, a synchronous acquisition method for dual-channel frequency hopping communication system was proposed. This method combined synchronization header method with parallel acquisition, used carrier frequency and modulated time information in synchronization process to determine frequency hopping time, and carried out parallel acquisition on two receiving channels to shorten synchronization time, improved synchronization concealment and anti-jamming ability. The simulation results showed that, compared with single channel acquisition, the proposed two-channel synchronization acquisition method reduced the initial synchronization time to 1/2 of the original one when the acquisition probability was basically unchanged, and effectively utilized the dual channel resources of the receiver.
