序列移相跳频组网分析与设计

为了提高跳频网络的通信效率，提出了利用同一跳频序列的相位差异实现跳频组网的方案。首先，以m序列为例分析了跳频序列移相的原理和实现方法；然后，将管理通道和数据通道相分离进行序列移相跳频组网设计和网络协议规划，给出了跳频序列的移相值优化方案。该方案具有网络管理灵活方便、通信效率高、抗干扰能力强等特点。仿真结果表明，序列移相跳频组网的网间干扰与异步组网相比有较大幅度改善。

Design and analysis of sequence phase-shifting frequency-hopping communication network

To improve the efficiency of frequency-hopping(FH) communication network, FH-sequence phase-shifting is used to build FH communication network. First, the theory and method of sequence phase-shifting is analysed based on the m sequence. Second, the networking process and protocol are expounded in great detail while the system is divided into control channel and data flow channel. And a method is proposed to optimize the phase-shifting value.Such advantages as flexibility in network control, high efficiency and powerful anti-jamming performance are shown for the new designed network. The simulation results show that sequence phase-shifting FH communication network possesses a low inter-network interference compared with asynchronous network.
