Abstract

In this paper, we propose a new structure for spectrum sensing which employs multiples energy detectors in multiple antenna system in order to improve its reliability. The performance is analyzed by simulation and compared to that of the conventional energy detector. The simulation results shows that the performance of the proposed scheme is much better than that of the conventional one. Additionally, the performance of is described in terms of ROC curve.

본 논문에서는 다중 안테나 시스템에서 다수의 에너지 검출기를 이용하여 신뢰성 향상을 도모한 새로운 스펙트럼 검출 방법을 제안하였다. 스즈키 채널 상황 하에서 시뮬레이션을 통하여 기존의 에너지 검출기와 스펙트럼 검출 성능 비교하였다. 시뮬레이션 결과 10%로 고정된 오보확률에서 제안하는 구조의 성능을 SNR (Signal to Noise Ratio)에 따른 미 검출 확률로 구하고 또한 ROC(Receive Operation Characteristics) 커브로 나타내어 그 우수함을 보인다.
