본 논문에서는 DS-UWB(Direct Sequence-Ultra Wideband) 다중 경로 채널 모델을 위한 적응형 등화기와 LMS-RAKE(Least Mean Square-RAKE) 결합 방식 수신기 시스템을 제안합니다. 제안 시스템의 주요 목적은 다중 경로 채널에서 초단 펄스의 고속 전송 시 ISI(Inter-Symbol Interference) 발생으로 인한 UWB 전송 성능 저하를 극복하는 것이다. 제안하는 시스템은 LMS-RAKE 수신기를 이용하여 다중경로 효과를 완화시키고 적응형 등화기를 이용하여 ISI 효과를 억제함으로써 시스템 성능을 향상시킨다. 시뮬레이션 결과는 특히 심각한 ISI 영향을 받는 채널 CM3 및 채널 CM4와 같은 UWB 다중 경로 채널 모델에서 제안된 시스템에 의해 상당한 등화 이득을 얻을 수 있음을 검증합니다.

Abstract: This paper proposes a combination of adaptive equalizer and Least Mean Square-RAKE (LMS-RAKE) combining scheme receiver system for Direct Sequence-Ultra Wideband (DS-UWB) multipath channel model. The main purpose of the proposed system is to overcome the performance degradation for UWB transmission due to the occurrence of Inter-Symbol Interference (ISI) during high speed transmission of ultra short pulses in a multipath channel. The proposed system improves the system performance by mitigating the multipath effect using LMS-RAKE receiver and suppressing the ISI effect with the adaptive equalizer. Simulation results verify that significant equalization gain can be obtained by the proposed system especially in UWB multipath channel models such as channel CM3 and channel CM4 that suffered severe ISI effect.
