Secure Degrees of Freedom in K-Helper MIMO Cognitive Radio Systems with No Eavesdropper CSI


Secure degrees of freedom (DoF) in MIMO cognitive radio system is studied in this paper. We consider a cognitive radio system with one primary source-destination pair, multiple secondary source-destination pairs and an eavesdropper against whom the primary user intends to secure its data. In this system, multiple secondary user pairs help to secure primary… (More)
