Abstract

Due to the ultrawide band property of an UWB pulse, it is difficult to digitally implement a TR-UWB system in time domain. In order to overcome this problem, we propose two types of TR-UWB systems which can be implemented in frequency-domain. One of thorn is derived from the Parseval's theorem, which results in its system performance equitable to that of time-domain based system. In addition, we propose another receiver structure which can improve the performance by exploiting the complex nature of the frequency components. Finally, through simulations, we compare the performances of two receiver structures with the time domain counterpart.

본 논문은 UWB 신호의 초광대역 특성으로 인해서 시간영역에서 디지털적 구현이 어려운 TR-UWB 시스템을 주파수영역에서 구현할 수 있는 방법을 제시한다. 한 시스템은 Parseval 정리로부터 유도되었으며 그로 인해 시간영역에서 구현되는 TR-UWB 시스템과 동일한 성능을 갖는다. 또한 주파수 성분들의 복소수 특성을 이용해서 성능을 보다 개선할 수 있는 새로운 구조의 TR-UWB 시스템을 제시한다. 마지막으로 시뮬레이션에 의해서 시간영역에서 구현될 수 있는 TR-UWB 시스템과 주파수영역 시스템들 간의 성능을 비교한다.
