| 摘 要： | 研究了超宽带脉冲无线电(impulseradio-IR)方案的抗干扰性能。首先分析了超宽带技术与传统的直接序列扩频技术的区别,然后建立了TH-IR和DS-IR超宽带系统的仿真模型,得到两种IR系统在多种干扰条件下的误码率性能。研究结果表明在单音干扰,多音干扰,部分频带,阻塞干扰下,DS-IR方案的抗干扰能力都比TH-IR强。这为脉冲无线电技术在军事通信系统中的应用提供了参考。

| Abstract: | Research on jam resistance performance of impulse radio (IR) system. These are time-hopping impulse radio (TH-IR) and direct-sequence impulse radio (DS-IR). The difference between UWB and the traditional direct sequence spread spectrum technology was analyzed,and the simulation models of TH-IR and DS-IR systems were installed. Appling the simulation models,the bit-error rate of the two IR systems were made in the presence of interferences. The research shows that the jam resistance performance of DS-IR is better than TH-IR in the presence of tone,multition,partial-band and barrage interference or jamming,which could be provided as a reference to the application of IR in military communication system. |
