Non-Linear Age of Information: An Energy Efficient Receiver-Centric Approach
Nikolaos I. Miridakis, Theodoros A. Tsiftsis, Guanghua Yang
The age of information (AoI) performance metric for point-to-point wireless communication systems is analytically studied under Rician-faded channels and when the receiver is equip…
Distributed Spatial Multiplexing Systems with Hardware Impairments and Imperfect Channel Estimation under Rank- Rician Fading Channels
Nikolaos I. Miridakis, Theodoros A. Tsiftsis, Corbett Rowell
The performance of a multiuser communication system with single-antenna transmitting terminals and a multi-antenna base-station receiver is analytically investigated. The system op…
On the Joint Impact of Hardware Impairments and Imperfect CSI on Successive Decoding
Nikolaos I. Miridakis, Theodoros A. Tsiftsis
In this paper, a spatial multiplexing multiple-input multiple-output (MIMO) system when hardware along with RF imperfections occur during the communication setup is analytically in…
Simultaneous Spectrum Sensing and Data Reception for Cognitive Spatial Multiplexing Distributed Systems
Nikolaos I. Miridakis, Theodoros A. Tsiftsis, George C. Alexandropoulos +1
A multi-user cognitive (secondary) radio system is considered, where the spatial multiplexing mode of operation is implemented amongst the nodes, under the presence of multiple pri…
