Abstract

In this paper, we analyze and simulate the performance of RAKE receiver for ultra wide band (UWB) systems in indoor multipath radio channel. Pulse position modulation-time hopping (PPM-TH) signal is considered. And we also consider three types of RAKE receivers, which are ideal RAKE, selective RAKE, and partial RAKE receivers. The indoor channel is modeled as the modified Saleh and Valenzuela (SV) model which has been proposed as a UWB channel model by the IEEE group, IEEE 802.15.SG3a.

본 논문에서, 실내 다중 경로 무선 채널에서 초광대역(UWB: ultra wide band) 시스템을 위한 레이크 수신기의 성능을 분석한다. 펄스 위치-시간 도약(PPM-TH: pulse position modulation-time hopping) 신호가 고려되었다. 그리고 또한 이상적인 레이크, 선택적 레이크, 부분적 레이크 수신기 등의 세 종류의 레이크 수신기를 고려한다. 실내 채널은 IEEE 802.15.SG3a에서 UWB 채널 모델로 제안한 수정된 SV (Saleh and Valenzuela) 모델로 모델링하였다.
