摘要
从通信干扰角度,基于频域分析方法,针对跳时-脉冲位置调制-超宽带(TH-PPM-UWB)体制,分析了不同噪声干扰信号对通信系统的干扰效果,并运用MATLAB仿真软件,在AWGN信道下,对不同噪声干扰信号的干扰效果进行了蒙特卡洛实验仿真,并对实验结果进行了对比分析,给出了干扰效果(误比特率)与噪声干扰信号功率、带宽和中心频率的关系。为实现对超宽带通信系统干扰的实装研制打下理论基础,具有一定的军事价值。
In the perspective of communication countermeasure,by the way of frequency analysis,this study analyzed the effect of noise jamming signal on Time Hopping-Pulse Position Modulation-Ultra Wide Band（TH-PPM-UWB） communication system.The jamming results of noise jamming signal to the Ultra Wide Band（UWB） communication system were simulated in the Monte Carlo experiment by MATLAB program,and the relationship among the signal power,bandwidth,center frequency and Bit Error Ratio（BER） were given.It has laid the theoretic foundation for manufacturing practical equipment.
