Kertas kerja ini memperkenalkan reka bentuk penghantaran cekap tenaga untuk rangkaian radio kognitif (CR) penuaian tenaga berbilang input output tunggal (MISO) dengan kehadiran penyadap suara luaran (Eves). Disebabkan oleh ciri-ciri sedia ada rangkaian CR dengan maklumat wayarles serentak dan pemindahan kuasa (SWIPT), Eves boleh mengakses jalur pengguna utama (PU) secara tidak sah, dan mesej sulit terdedah untuk dipintas dalam komunikasi wayarles. Dengan mengandaikan maklumat keadaan saluran (CSI) Hawa tidak diketahui dengan sempurna pada pemancar, pendekatan kami untuk menjamin kerahsiaan adalah untuk memaksimumkan kecekapan tenaga rahsia (SEE) dengan mereka bentuk bersama pembentukan rasuk yang teguh dan nisbah pemisahan kuasa (PS), di bawah kekangan jumlah kuasa penghantaran, tenaga yang dituai pada penerima sekunder (SR) dan keperluan kualiti perkhidmatan (QoS). Khususnya, model penuaian tenaga bukan linear (EH) diguna pakai untuk SR, yang boleh mencirikan sifat litar RF-EH praktikal dengan tepat. Untuk menyelesaikan masalah bukan cembung yang dirumuskan, kita mula-mula menggunakan teori pengaturcaraan pecahan dan fungsi penalti untuk menyusun semula ia sebagai masalah parametrik yang mudah dikendalikan, dan kemudian menangani bukan cembung dengan menggunakan Prosedur S dan prosedur cembung terkurung ( CCCP), yang membolehkan kami mengeksploitasi perbezaan pengaturcaraan fungsi cekung (DC) untuk mendapatkan kes terburuk maksimum SEE. Akhir sekali, keputusan berangka dibentangkan untuk mengesahkan prestasi skim yang dicadangkan.

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.
