초록

현재 WPAN(Wireless Personal Area Network) 전송기술의 하나인 IEEE 802.15.4a의 저속형 UWB(Ultra Wide Band) 기술이 활발하게 연구되어지고 있다. 하지만 IEEE 802.15.4a에서 제시된 WPAN 전송채널의 경우에는 심각한 멀티패스 간섭성분이 존재하여 이에 대한 해결방안이 절실히 요구되어지고 있다. 따라서 본 논문에서는, WPAN 환경에서 전송채널의 심각한 멀티패스 성분을 물리계층(Physical layer) 레벨에서 근원적으로 해결하여 높은 QoS(Quality of Service)를 확보하게 해줄 수 있는 단극형 ZCD(Zero Correlation Duration)확산코드 기반의 Chaotic-OOK (On-Off Keying) 무선통신기술을 제안하고 IEEE 802.15.4a 채널 환경하에서의 모의실험을 통한 성능평가와 핵심 모듈에 대한 하드웨어의 구현을 통해 제안한 무선통신기술의 유용성을 입증하였다.

Recently, IEEE 802.15.4a(low-rate UWB) technique has been paid much attention to the LR-UWB communication system for WPAN. However, there are various interferences such as MPI(Multi Path Interference) or IPI(Inter Piconet Interference) in IEEE 802.15.4a wireless channel. In order to cancel various interferences occurred to WPAN environment, in this paper, we propose a UWB wireless communication system with high QoS(Quality of Service) which is a chaotic-OOK(On-Off Keying) system using unipolar ZCD(Zero Correlation Duration) spreading code in physical layer level. Furthermore, we analyze its performance via simulations and verify the availability of proposed system with prototype implementation.
