摘要

介绍了一种适用于DS-CDMA接收机的自适应抽头延迟线均衡器。这种结构,无需修改,可以应用于使系统对传输脉冲形状的频谱无效率不敏感(通过拒绝多址噪声),在存在多径干扰时充当RAKE,并拒绝窄带干扰。后一种性质是本文研究的重点;该技术与先前发表的窄带噪声抑制方法进行了比较。

Anti-jamming properties of a DS-CDMA equalization filter
An adaptive tapped delay line equalizer is described which operates in a DS-CDMA receiver. This structure, without modification, can be applied to make the system insensitive to spectral inefficiency of the transmitted pulse shape (by rejecting multiple-access noise), to act as a RAKE in the presence of multipath interference, and to reject narrowband interference. The latter property is the main focus of this paper; this technique is compared to previously published methods of narrowband noise rejection.<>
