Abstract

In this paper, the spectrum sharing cognitive radio network is investigated. For assuming that channels for the secondary network are double Rayleigh fading channels, we derive the exact and the approximate outage probabilities. Numerical results verify the validity of our theoretical analysis by comparison with Monte Carlo simulation results.

본 논문에서는 스펙트럼 공유 인지 무선 네트워크를 다룬다. 2차 사용자 네트워크의 채널을 더블 레일리 페이딩으로 가정하였을 때 정확한 불능 확률 값을 수식유도를 통해 구하고 불능 확률의 근사식 또한 얻어낸다. 모의실험을 통해 분석한 불능 확률이 정확함을 확인하였고 1차 사용자에서의 최대 허용 간섭 변화에 따른 성능변화를 확인하였다.
