광대역 다중경로 실측채널에서 W-CDMA 수신 신호의 확률분포 모델
Probability Distribution Model of Received W-CDMA Signals in the Realistic Wideband Multipath Channel
초록
This paper presents a mathematical model of the output of Rake receiver of W-CDMA signals for various outdoor channel environment and different bandwidths. This mathematical model is represented as Rayleigh and noncentral chi distribution with 3 degrees of freedom. Those are obtained from the statistics of numerically generated signals. We employ Chi-square test to show how the mathematical model fits signal statistics, and confirmed that this model is appropriate for representing W-CDMA signals.
