4G移动通信技术在军事隐身通信系统中的应用初探

Discussion on the Application of 4G Mobile Communication Technique in Military Stealthy Communication System

通过研究4G移动通信技术在军事隐身通信系统中的应用，根据军事通信的需求和军事通信信道的特点，初步设计出一种应用正交频分复用（OFDM）、直接序列扩谱（DSSS）、多输入多输出（MIMO）和智能天线（SA）技术，隐身性能较好，传输数据较快的军事隐身通信系统。并运用MATLAB仿真技术对该系统所采用的自适应可变扩谱因子（VSF）多载波直扩通信体制VSF／MC-DS进行仿真，验证了该隐身通信系统的抗干扰性能、高数据速率和可行性。

Based on the discussionon the application of 4G mobile communication technique in military stealthy communication system, and according to the requirements of military communi- cation and the characteristics of military communication channel, a military stealthy communi- cation system is designed. This system adopts the techniques such as OFDM, DSSS, MIMO, and SA. It has good stealthy performance and fast data transmission performance. The self-a- daptive VSF/MC-DS scheme adopted by this system is simulated. And simulation result dem- onstrates the anti-jamming performance, fast data transmission performance and the feasibility of the system.
