摘要
该文基于直扩系统原理,建立了PN序列直扩系统仿真模型,利用Matlab工具仿真分析了系统在宽带干扰、单音干扰和脉冲干扰下的性能,并对编码和同步对系统误码性能的影响作了仿真研究,最后总结了直扩抗干扰性能。
Based on the principle of DSSS,a PN sequence DSSS simulation model was established in this paper.Then the performance of system in band jamming,single tone jamming,and pulse jamming were analyzed and simulated respectively by using Matlab 7.0,also the impact of coding and synchronization on its performance were studied. Finally,the corresponding conclusion of antijamming performance was summarized.
