Abstract

In this paper, we propose a digitally implementable synchronization method for the UWB system. This is achieved by manipulating the frequency components of a synchronizing signal which is the sequence of pulses of periodicity. We analyze the dependancy of the number of pulses and pulse interval on the intrinsic synchronization accuracy. Moreover, through the computer simulation, the performance of the proposed method is examined via varying system parameters.

본 논문은 주기적인 펄스열 형태의 동기 신호로부터 주파수 성분들을 추출한 후 이를 이용해서 디지털적으로 구현 가능한 UWB 신호 동기 검출 방법을 제시한다. 동기 신호의 펄스 개수 및 펄스 간격이 동기 검출 성능에 미치는 영향 및 제시된 방법으로 얻을 수 있는 동기의 정확도를 이론적으로 분석한다. 또한, 시뮬레이션을 통하여 이론적 분석 결과를 검증하고 AWGN 환경에서의 제시된 방법의 성능을 보인다.
