摘要
远程视频监控系统中提高系统的可靠性和稳定性很重要。针对这一问题提出在系统中采用DS/FH混合扩频技术。详细讨论了采用DS/FH混合扩频通信技术系统的抗宽带阻塞干扰、多径干扰性能,并通过SYSTEMVIEW仿真软件进行仿真分析,分析和仿真结果表明了采用此技术的可行性。给出了该通信模式下的系统模型,为实际系统的设计与实现奠定了基础。
It is an important issue to improve the reliability and stability of the system in remote video monitoring system.Aiming at the problem,this paper presents a method which uses hybrid DS/FH spread-spectrum technology in the system.In this paper,we firstly discuss in detail the performances of anti-wideband jamming and anti-multipath interference.The simulation is implemented by using the simulation software SYSTEMVIEW,and the simulation results show that this technology is feasible.The system model under this communication model is given in the last part, which will establish the foundation for the analysis and design of practical system.
