摘要
超宽带通信是继CDMA与蓝牙技术之后出现的一种非常有发展前途的无线通信技术。本文首先介绍了UWB基本原理,然后着重从频域角度探讨了PAM-TH-UWB系统对CDMA干扰的抑制能力,得出了合理选择超宽带信号的基本参数以及不同的调制方式,可在一定程度上提高超宽带系统抗干扰能力的结论。
Ultra Wide Band （UWB） communication technology is a very attractive technology of wireless communication after CDMA and blue-tooth, This paper Introduces the basic elements of UWB at first. Then the Interference of system is analyzed from the angle of frequenoy domain; It concludes that the Interference can be reduced on some extent by choosing the basle parameter of UWB and different modulation technology properly.
