Abstract

In this paper, we propose an incremental cooperative transmission protocol in two-way underlay cognitive radio networks. In the proposed protocol, two secondary sources attempt to transmit their packet to each other with help of a secondary relay under interference constraint. For performance evaluation, we derive exact closed-form expressions of average outage probability over Rayleigh fading channel. Then, we perform Monte Carlo simulations to verify the derivations. Results present that the simulation and theoretical results are in good agreement and the outage performance of the proposed protocol is better than that of two-way direct transmission protocol.

본 논문에서는, 양 방향 언더레이 인지 네트워크의 점진적 협력 전송을 제안한다. 제안된 프로토콜은 두 2차 소스가 간섭 조건에 따라 보조 릴레이의 도움으로 서로의 패킷을 전송하려 시도하는 것이다. 성능 평가를 위해, 레일리히 페이딩 채널의 평균 정전 확률에 대한 폐구간의 정확한 식을 유도한다. 또한, 유도된 식을 확인하기 위해 몬테카를로 시뮬레이션을 수행한다. 그 결과, 시뮬레이션과 이론적 결과가 일치하며, 제안된 프로토콜의 정전 확률은 양방향 직접 통신 프로토콜보다 더욱 우수하다.
