multi-antenna secrecy communications
On the relationship between the multi-antenna secrecy communications and cognitive radio communications FREE-DOWNLOAD [PDF] L Zhang, R Zhang, YC Liang… – Communications, research …, 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 ..
multiple-antenna users
Power allocation for a MIMO relay system with multiple-antenna users FREE-DOWNLOAD [PDF] 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 […]
slot antenna
A dual-polarization slot antenna using a compact CPW feeding structure FREE-DOWNLOAD [PDF] Y Li, Z Zhang, W Chen, Z Feng… – … Letters, research, 2010 Abstract—A dual-polarization coplanar waveguide (CPW)-fed slot antenna is proposed in this letter. By exploiting the even and odd modes of a CPW structure, two orthogonal polarizations can be excited in a slot aperture by […]
