초록

본 논문에서는 다중사용자 간섭이 존재하는 M-ary TH-PPM 시스템에서 확률분포 모델에 기반하는 개선된 초광대역 Rake 수신기법이 연구되었다. Rake 수신기의 성능 향상을 위해서 다중사용자 간섭과 잡음의 혼합 분포를 유연하게 근사할 수 있는 확률모델이 필요하며, 본 연구에서는 라플라스분포와 첨두치 정합(kurtosis matching) 기법이 적용된 일반화된 정규 라플라스 모델이 고려되었다. 각 확률분포에 기반하는 Rake 수신기의 성능이 IEEE 다중 경로 페이딩 채널에서 평가되었고 종래의 Rake 수신기와 비교 되었다. 제안된 접근법은 종래의 Rake 수신기보다 더 우수한 BER 성능을 보인다.

In this paper, an advanced UWB (ultra wideband) Rake receiving technique based on the statistical distribution model is studied in the M-ary TH-PPM system with multiple access interference (MAI). In order to improve the performance of the Rake receiver, the stochastic model, which can flexibly express the behavior of MAI-plus-noise, is required and the Laplace distribution and the generalized normal Laplace (GNL) model applied by the curtosis matching method are considered. The performance of Rake receiver based on each probability distribution is evaluated in the IEEE multipath fading channel and compared to that of the conventional Rake receiver. The suggested approach shows a superior BER performance than that of conventional Rake receiver.
