본 논문에서는 UWB(Ultra-Wideband) 무선통신 기술의 정의와 기본 이론에 대해 설명하고 현재 IEEE 802.15.3a에서 추진중인 근거리 고속 데이터 전송 물리계층의 표준화에 UWB의 기술을 도입하기 위한 표준화 현황 및 이를 위하여 제안된 시스템안인 Direct-Secquence USB(DS-UWB) 시스템과 Multi-Band OFDM(MB-OFDM) 시스템을 분석하여 각 시스템의 특징을 제시하고 이에따라 현재 UWB PHY의 기술 동향에 관해 논의하였다.
Abstract
Upcoming Ultra-Wideband (UWB) radio technology has recently been announced to use for imaging systems, communication & measurement systems, and vehicular radar systems with limited emission power. In this paper the definition and general theories about UWB compared with conventional narrowband communication systems were presented. Also Direct-Sequence UWB (DS-UWB) and Multi-Band OFDM (MBOFDM) proposal which were proposed in IEEE 802.15.3a standard, which was aimed for high data-rate wireless connectivity, were generally discussed. The characteristics of two proposals were compared, then finally the technical trends and standard issues of UWB physical layers were shown.
