Performance Analysis of the CDMA system with the RAKE Receiver over a Multipath Fading Channel
다경로 페이딩 채널에서 RAKE 수신기를 적용한 CDMA 시스템의 성능 분석
Abstract
This paper presents the CDMA system using the RAKE receiver over a multipath fading channel and in multi-user environments. The interference between the propagation paths in a multipath fading causes a serious degradation in the mobile communication environment. In order to derive the path inteference and reduce the fading effect, the RAKE receiver is used. In a computer simulation, the path number of a fading channel and the branch number of the RAKE receiver are modified. As a result, the CDMA system using the RAKE receiver gives a better performance than the conventional CDMA system over a multipath fading channel and in multi-user environments.
