摘要

超宽带(UWB)无线电不可避免地会引起附近现有窄带系统的严重干扰。因此，脉冲是通过在某些频率形成陷波来施加的，作为抑制其干扰的一种方式。本文提出并比较了两种基于切比雪夫函数近似的超宽带脉冲(采用Parks-McClellan (PM)算法)和基于扩展球面波函数(PSWF)函数的超宽带脉冲(采用特征值分解(EVD)算法)。产生的超宽带脉冲不仅满足美国联邦通信委员会(FCC)的要求，而且还能减轻单频段和多频段窄带干扰(NBI)。

A comparative study of two UWB pulse design methods for narrowband interference mitigation

Ultra Wideband (UWB) radios will unavoidably cause severe interference from the existing narrowband systems nearby. Therefore pulses are applied by forming notches at some frequencies as a way to suppress its interference. This paper present and compare two UWB pulses based on Chebyshev function approximation by using the Parks-McClellan (PM) algorithm and Prolate Spherical Wave Functions (PSWF) function by using Eigenvalue Decomposition (EVD) algorithm. The generated UWB pulses not only meet the Federal Communications Commission (FCC), but also mitigate single and multiple narrow-band interference (NBI).
