【摘要】 跳频通信是扩频通信的一种形式,具有很好的抗干扰和抗截获特性。跳频同步是跳频系统的关键部分,决定了整个系统的性能,而跳频同步跟踪的性能决定了同步精度、系统的误码率性能,同时还影响了同步时间的长短,本文对常规的基于时钟信号的跟踪方法进行了改进,提高了跟踪过程的精度,缩短了跟踪过程的时间,节省了硬件资源。更多还原

【Abstract】 Frequency hopping communication is a form of spread spectrum communication, and it has a good performance of antiinterference and anti-interception.Frequency hopping synchronization is a key part of frequency hopping system, it determines the performance of the whole system.However, the performance of FH synchronization tracking decides the synchronization precision and the system BER performance, at the same time also affects the length of synchronization time.In this paper, the common synchronization tracking method based on the clock signal is improved, it improves the tracking accuracy, shorten the time of tracking process and saves the hardware resources.更多还原
