On the relationship between the multi-antenna secrecy communications and cognitive radio communications
FREE-DOWNLOAD L Zhang, R Zhang, YC Liang… – … , research Transactions on, 2010 Abstract—This paper studies the achievable rates of the multi-antenna or multiple-input multiple-output (MIMO) secrecy channel with multiple single-/multi-antenna eavesdroppers. By assuming Gaussian input, the maximum achievable secrecy rate is obtained with the .

Power allocation for a MIMO relay system with multiple-antenna users
FREE-DOWNLOAD Y Yu… – Signal Processing, research Transactions on, 2010 – Abstract—A power allocation or scheduling problem is studied for a multiuser multiple-input multiple-output (MIMO) wireless relay system where there is a non-regenerative relay between one access point and multiple users. Each node in the system is equipped with multiple
