摘要
针对基于直接序列调制扩展频谱通信技术的"人在回路"数据链建模仿真问题,以Matlab中的Simulink软件包作为工具建立基于Simulink仿真平台的"人在回路"数据链的仿真模型,给出加入窄带干扰后的动态仿真实例,并得到整体系统仿真中各关键模块处理后信号的频谱图,实验结果证明了该建模方法的有效性。
Aiming at the problem of modeling and simulation of ＂man in the loop＂ data chain based on direct sequence spread spectrum communication technology modulation, this paper utilizes Simulink of software bundle in Matlab to construct simulation model of ＂man in the loop＂ data chain based on Simulink platform. Dynamic simulation example of joining after narrowband interference is given, and signal spectrum charts of each key module are given. Experimental results show that the modeling method is effective.
