摘　　要：在UWB研究领域,存在着两种技术解决方案:一种是基于脉冲UWB形式,采用直接扩频作为多址方式的UWB通信方案即DS-UWB;另一种是基于传统OFDM技术的多带UWB方案,即MB-OFDM-UWB。UWB凭借其自身特点可以应用在短距离无线通信、定位和探测等领域。随着研究的深入,UWB技术不断与新技术融合,具有更广阔的应用前景。The development of UWB technique and its standardization are introduced in this paper. The schemes of pulse UWB and multi -band UWB as well as their key realization techniques are also analyzed. UWB, with its characteristics, can be applied in short-range wireless communication, positioning and detection. In combination with other new technologies, UWB has wider application.
