초록

본 논문에서는 통화량이 많은 상황에서 인지 무선 시스템을 위한 센싱 구간 분할 기반 스펙트럼 센싱 기법을 제안한다. 구체적으로는 센싱 구간을 K개의 구간으로 분할하고, 각 분할된 구간에 스펙트럼 센싱을 수행한 결과들로부터 최종적으로 일차 사용자 신호의 유무를 판단하는 스펙트럼 센싱 기법을 제안한다. 모의실험을 통해 제안한 기법이 통화량이 많은 상황에서 기존 기법들에 비해 더욱 우수한 스펙트럼 센싱 성능을 가짐을 확인한다.

In this paper, we propose a novel spectrum sensing scheme based on sensing time partitioning for cognitive radio systems in high traffic environments. Specifically, we partition a sensing time into K sub-sections, and then, propose a spectrum sensing scheme that determines if a primary user signal is present based on the sensing results on the partitioned sub-sections. From numerical results, it is confirmed that the proposed scheme outperforms the conventional schemes in high traffic environments.
