초록

본 논문은 레일라이 페이딩과 로그노말 새도우잉에 의한 영향뿐 아니라 도심지역에 혼재해 있는 인공잡음을 고려하여 이동 무선 채널파 전파특성을 분석하였다. 잡음의 존재 여부가 이동 무선 시스템에 어떠한 영향을 미치는가에 대해서 기존의 모델링과 outage 확률값을 비교하였다. 도심지역의 효과적인 무선 전파의 분석올 위해서 페이딩과 새도우잉 그리고 잡음을 복합적으로 고려하였다. N=O.OOOOOI인 조건에서 잡음을 고려하지 않은 경우 outage 확률값은 $5.624\times10^{-6}$, 페이딩만을 고려한 경우는 $3.1976\timeslO^{-4}$, 잡음을 고려한 모텔에서는 $6.0\times10^{-3}$ 을 나타냈다. 잡음올 무시한 채널 모델령과 해석은 시스템의 성능평가에 상당한 오류를 야기될 수 있음올 밝혔다.

In this paper, considering the Rayleigh fading, the lognormal shadowing, and the man-made noise which is occurred in urban area randomly, the mobile radio channel and the radio propagations are analyzed. The system affected by the noise is compared to other modelings. The fading, shadowing, and background noise are wholly considered to evaluate the mobile radio propagation effectively. For N=0.000001, the outage probability in the absence of noise is $5.264{times}10^{-6}$, in the fading only $3.1796{times}10^{-4}$, and in the presence of noise $6.0{\times}10^{-3}$. The analysis with the presence of noise is very important for the performance evaluation of mobile radio system.
