抗干扰能力是超宽带通信技术必须研究的关键问题之一。建立了部分频带干扰模型和超宽带通信系统模型,并忽略背景热噪声的影响。通过理论分析和实验仿真,分析了脉冲参数和跳时码参数与超宽带通信系统抗干扰性能之间的关系。最后,通过分析比较得出了一些有益的结论,为脉冲无线电技术在未来的实际应用提供了有价值的参考。 Anti-interference ability is one of the key issues that must be studied in UWB technology. The partial frequency band interference model and UWB communication system model are established, and the influence of background thermal noise is ignored. Through theoretical analysis and experimental simulation, the relationship between pulse parameters and time hopping code parameters and anti-jamming performance of UWB communication system is analyzed. Finally, some useful conclusions are drawn through the analysis and comparison, which provides a valuable reference for the practical application of pulsed radio technology in the future.
