Robust Transmission Design for IRS-Aided Secure Cognitive Radio Systems Against Internal Eavesdropping

A robust transmission scheme for intelligent reflecting surface (IRS) aided cognitive radio systems is designed to provide security against internal eavesdropping. By considering the secondary receiver as an internal eavesdropper, a total transmit power (TTP) minimization problem is formulated. Thro...
