이 문서에서는 외부 도청자(Eves)가 있는 경우 다중 입력 단일 출력(MISO) 에너지 수확 인지 무선(CR) 네트워크를 위한 에너지 효율적인 전송 설계를 소개합니다. SWIPT(동시 무선 정보 및 전력 전송)를 갖춘 CR 네트워크의 고유한 특성으로 인해 Eves는 기본 사용자(PU) 대역에 불법적으로 액세스할 수 있으며 무선 통신에서 기밀 메시지가 가로채기 쉽습니다. Eves의 채널 상태 정보(CSI)가 송신기에서 완벽하게 알려져 있지 않다고 가정할 때, 비밀성을 보장하기 위한 우리의 접근 방식은 다음과 같이 강력한 빔 형성과 전력 분할(PS) 비율을 공동 설계하여 비밀 에너지 효율(SEE)을 최대화하는 것입니다. 총 전송 전력, 보조 수신기(SR)에서 수확된 에너지 및 서비스 품질(QoS) 요구 사항의 제약. 특히, SR에는 비선형 에너지 하베스팅(EH) 모델이 채택되어 실제 RF-EH 회로의 특성을 정확하게 특성화할 수 있습니다. 공식화된 비볼록 문제를 해결하기 위해 먼저 분수 계획법 이론과 페널티 함수를 사용하여 이를 다루기 쉬운 매개변수 문제로 재구성한 다음 S-절차와 제한된 오목 볼록 절차를 적용하여 비볼록성을 처리합니다( CCCP)를 사용하면 DC(오목 함수) 프로그래밍의 차이를 활용하여 최대 최악의 SEE를 찾을 수 있습니다. 마지막으로 제안한 기법의 성능을 검증하기 위해 수치 결과를 제시한다.

Abstract: This paper introduces an energy-efficient transmit design for multiple-input single-output (MISO) energy-harvesting cognitive radio (CR) networks in the presence of external eavesdroppers (Eves). Due to the inherent characteristics of CR network with simultaneous wireless information and power transfer (SWIPT), Eves may illegitimately access the primary user (PU) bands, and the confidential message is prone to be intercepted in wireless communications. Assuming the channel state information (CSI) of the Eves is not perfectly known at the transmitter, our approach to guaranteeing secrecy is to maximize the secrecy energy efficiency (SEE) by jointly designing the robust beamforming and the power splitting (PS) ratio, under the constraints of total transmit power, harvested energy at secondary receiver (SR) and quality of service (QoS) requirement. Specifically, a non-linear energy harvesting (EH) model is adopted for the SR, which can accurately characterize the property of practical RF-EH circuits. To solve the formulated non-convex problem, we first employ fractional programming theory and penalty function to recast it as an easy-to-handle parametric problem, and then deal with the non-convexity by applying S-Procedure and constrained concave convex procedure (CCCP), which enables us to exploit the difference of concave functions (DC) programming to seek the maximum worst-case SEE. Finally, numerical results are presented to verify the performance of the proposed scheme.
