초록

본 논문에서 이동 대 이동 Rayleigh 및 Rician 페이딩 채널 상에서 시뮬레이션 모델의 성능이 분석되고 그 결과가 비교된다. Clarke의 페이딩 모델의 수신 신호 및 Clarke의 페이딩 모델에서 위상 천이된 수신 신호에 근거한 자기 상관 함수 및 상호 상관 함수를 유도하고, 그 시뮬레이션 모델의 결과를 구하였다. 또한 이동 대 이동 Rician 페이딩 채널에 이 두 모델을 적용하고, 복소 포락선 수신 신호의 자기 상관 함수 결과는 통계적 특성이 이론값과 매우 일치하고, N=8인 작은 수에서도 빨리 수렴함을 보였다.

In this paper, the performance of simulation model in mobile to mobile Rayleigh and Rician fading channel is analyzed and simulation results are compared. The auto-correlation and cross-correlation functions of Rayleigh fading channels not only based on received signals of Clarke's fading model and but also based on received signals of phase shifted Clarke's fading model are derived and their simulation results are found. The two models are also applied to mobile to mobile Rician fading channel models and their numerical results of auto-correlation functions of complex envelop received signals shows the statistical properties match the theoretical values very well and rapidly converge with the small number such as N=8.
