Joint Channel Estimation and Pilot Allocation in Underlay Cognitive MISO Networks
Maha Alodeh, Symeon Chatzinotas, Bjorn Ottersten
Cognitive radios have been proposed as agile technologies to boost the spectrum utilization. This paper tackles the problem of channel estimation and its impact on downlink transmi…
Energy Efficient Symbol-Level Precoding in Multiuser MISO Channels
Maha Alodeh, Symeon Chatzinotas, Bjorn Ottersten
This paper investigates the idea of exploiting interference among the simultaneous multiuser transmissions in the downlink of multiple antennas systems. Using symbol level precodin…
Cellular-Broadcast Service Convergence through Caching for CoMP Cloud RANs
Symeon Chatzinotas, Dimitrios Christopoulos, Bjorn Ottersten
Cellular and Broadcast services have been traditionally treated independently due to the different market requirements, thus resulting in different business models and orthogonal f…
Constructive Interference in Linear Precoding Systems: Power Allocation and User Selection
Dimitrios Christopoulos, Symeon Chatzinotas, Ioannis Krikidis +1
The exploitation of interference in a constructive manner has recently been proposed for the downlink of multiuser, multi-antenna transmitters. This novel linear precoding techniqu…
User Scheduling for Coordinated Dual Satellite Systems with Linear Precoding
Dimitrios Christopoulos, Symeon Chatzinotas, Bjorn Ottersten
The constantly increasing demand for interactive broadband satellite communications is driving current research to explore novel system architectures that reuse frequency in a more…
Multi-User Detection in Multibeam Mobile Satellite Systems: A Fair Performance Evaluation
Dimitrios Christopoulos, Symeon Chatzinotas, Jens Krause +1
Multi-User Detection (MUD) techniques are currently being examined as promising technologies for the next generation of broadband, interactive, multibeam, satellite communication (…
