摘要
本文对传统脉冲、多频带OFDM、DS-CDMA等3种超宽带方案进行了介绍,在阐述其原理及异同点的同时,对不同方案的频谱使用以及相应的抗干扰技术进行了介绍,并且研究了超宽带系统与其它系统电磁兼容共存问题,给出了不同的电磁兼容方案。
This paper introduces the conventional pulse, multi-band OFDM and DS-CDMA ultra wideband techniques. The principles and features of these three techniques are presented. Meanwhile, their frequency management mechanisms are discussed and their interference suppression methods are analyzed. The coexistence problem between UWB and other communication systems is investigated and the corresponding strategies are researched.
