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…
Optimal Power Allocation and Active Interference Mitigation for Spatial Multiplexed MIMO Cognitive Systems
Nikolaos I. Miridakis, Minghua Xia, Theodoros A. Tsiftsis
In this paper, the performance of an underlay multiple-input multiple-output (MIMO) cognitive radio system is analytically studied. In particular, the secondary transmitter operate…
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…
