数字通信链路的Simulink仿真和干扰效果评估

对于干扰而言,选择干扰体制和设置合适的干扰参数一直是通信对抗的重点。客观、准确、定量地分析和评价对抗装备对数字通信链路的干扰效果对于提高干扰和抗干扰能力具有重要意义。仿真了对常用数字通信链路信号的干扰效果评估,采用的干扰样式有单音干扰、相关干扰、同步扰动干扰等,对各种干扰的干扰效果进行评估和比较,为优化干扰样式提供了基础。

Simulink Simulation and Jamming Effect Evaluation of Digital Communication Links

For jamming ,selecting the jamming system and setting suitable jamming parameters al-ways is the focal point of communication countermeasure .It has important meaning for improving jamming and anti-jamming capbility to analyze and evaluate the jamming effect of communication countermeasure equipments on digital communication links objectively ,accurately and quantitative-ly .T his paper simulates the jamming effect evaluation of common digital communication link sig-nals ,the adopted jamming modes includes single-tone jamming ,interrelated jamming ,synchroniza-tion disturbance jamming and so on ,evaluates and compares the effect of each jamming ,w hich pro-vides the base for optimizing the jamming mode .
