Abstract

In this paper, we propose a novel structure where the energy detector has multiples of verification using time delay in order to improve its performance. Additionally, the performance is investigated by simulation and compared to that of the original energy detector. The simulation result shows that the proposed scheme improves the performance when SNR is compared with the mis-detection probability for both 1% and 10% of false alarm probability. The performance is also described in terms of ROC.

본 논문에서는 에너지 검출기의 성능개선에 관한 것으로 시간 지연의 형태를 이용하여 복수번의 확인과정을 가지는 변형된 형태의 에너지 검출기를 채용하는 스펙트럼 검출 기법을 새로이 제안하고 시뮬레이션을 통하여 그 성능을 구해 기존의 에너지 검출기와 비교한다. 성능은 1%와 10%로 고정된 오보확률에서 SNR과 미검출 확률을 구하거나 ROC(Receive Operation Characteristics)로 구하여 제안 방식이 우수함을 보인다.
