超宽带抗干扰性能分析

System performance analysis of Ultra-Wide band in jamming environment

摘要: 研究了超宽带系统的抗干扰性能.基于TH-PPM-UWB系统,分析了超宽带在窄带和宽带干扰时的系统性能,利用ADS软件,建立了系统仿真模型,并分别仿真分析了2种干扰情况下的系统误码性能.仿真结果表明:窄带干扰中心频率及发送功率的大小对UWB系统的性能有较大影响,而增加宽带干扰,相当于增加热噪声幅度.

Abstract: The performance of UWB communication systems is studied in the jamming environment.The system performance of TH-PPM-UWB is analyzed,and a UWB interference bench is made by ADS.The BER performance of the UWB in narrowband interference and wideband interference are simulated respectively based on the bench.The results show that the center frequency and radiate power of narrowband interference affected the BER of UWB;increasing the wideband interference is equal to increasing the range of the noise.
