Abstract

In this paper, We applied CCI canceller to remove multiple access interference in co-channel environment and improved performance of Impulse Radio UWB system. Also, we have evaluated the performance of UWB system with Truncated Type-II Hybrid ARQ scheme for achieving high quality data transmission.

본 논문에서는 Impulse Radio UWB 시스템에서 다중 접속시 발생하는 간섭을 개선하기 위해 CCI canceller를 적용하여 동일 채널 상의 다중 접속 간섭을 제거 하였다. 또한, 전송 품질을 향상시키기 위하여 Truncated Type-II Hyabrid ARQ 기법을 적용하여 다중간섭 채널 환경에서의 시스템 성능을 평가하였다.
