- Abstract
- 이 논문에서는 2차사용자의 감지 성능이 서로 다른다중 채널 환경에서 그룹 기반 협동 스펙트럼 감지를위한 그룹화 알고리즘을 제안한다. 제안한 알고리즘은2차사용자의 오류 확률을 고려한 그룹화를 통해 감지정확도를 향상시킴으로써 전체 네트워크의 처리량을증가시킨다. 시뮬레이션 결과는 제안 된 알고리즘이기존 알고리즘에 비해 감지 정확도와 총 네트워크 처리량을 크게 향상시킬 수 있음을 보여준다.
In this paper, we propose a grouping algorithm for group-based cooperative spectrum sensing in multi-channel environments where the secondary users’ sensing performances are different. The proposed algorithm increases the total network throughput with a grouping by considering the error probability of secondary users. Simulation results show that the proposed algorithm can improve the sensing accuracy and total network throughput significantly compared to the conventional algorithm.
