基于附加频移的跳频同步组网设计与分析

为了提高跳频同步组网的频点利用率，提出了一种基于附加频移的跳频同步组网方案 。首先，给出了基于附加频移跳频通信的基本模型和收发双方的实现方案；然后，基于该跳 频通信模型，给出了同步组网的网络拓扑结构。该方案在整个工作频段内能够使用所有可用 频点进行同步组网，提高了频点利用率。分析结果表明，在相同子网数下，该方案较常规跳 频同步组网还具有更小的碰撞概率和比特差错率，同时该方案还增加了敌方的侦察分选难度 和干扰难度。

Design and analysis of frequency-hopping synchronization networking based on additional frequency shift

To improve the frequency utilization of frequency-hopping (FH) synchro nization networking, a scheme of FH synchronization networking based on addition al frequency shift is proposed. First, the model of FH communication based on ad ditional frequency shift and the implementation of transmitter and receiver side s are presented. Then,based on this FH communication model, network topology of synchronnization networking is provided. With this scheme, all the availab le frequencies in the operating band can be used for synchronization networking and the frequency utilization is also improved. Furthermore,the analysis indica tes that this scheme has lower hit probability and bit error rate(BER) under t he same networks compared with the conventional FH synchronization networking. Meanwhile, this scheme increases difficulties for hostile reconnaissance,sortin g and jamming.
