Abstract

In this paper, the proposed a narrowband interference cancellation techniques for the frequence sharing of Ultra wideband Impulse Radio communication system and narrowband communication system. In this system, the narrowband communication signals can cause intolerant interferences to Impulse Radio signals. In this paper, Ultra wideband Impulse Radio system have been analyzed in AWGN, MAI and NI(Narrowband Interference) environment. Also, performance improvement has been obtained by adopting an adaptive notch filtering scheme using Complex Filter Bank and CCI canceller. The results show that there is a substantial enhancement in performance by employing the adaptive notch filtering and/or CCI canceller.

본 논문에서는 근거리 무선환경에서 초광대역 Impulse Radio 시스템과 기존의 협대역 통신 시스템의 주파수 공존을 위한 협대역 간섭 제거 기법을 제안하였다. 협대역 통신 시스템은 Impulse Radio 시스템의 주파수 대역에서 협대역 간섭의 원인이 될 수 있다. 따라서, 본 논문에서는 다중간섭 및 협대역 간섭 환경에서 Impulse Radio 통신 시스템의 간섭 영향을 분석하고, 효과적인 성능 개선을 위하여 복소다중 필터뱅크와 CCI 간섭제거기를 동시에 채용함으로써 수신성능의 개선을 얻을 수 있었다.
