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…
MMSE Performance Analysis of Generalized Multibeam Satellite Channels
Dimitrios Christopoulos, Jesus Arnau, Symeon Chatzinotas +2
Aggressive frequency reuse in the return link (RL) of multibeam satellite communications (SatComs) is crucial towards the implementation of next generation, interactive satellite s…
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 (…
Eigenvalue Based Sensing and SNR Estimation for Cognitive Radio in Presence of Noise Correlation
Shree Krishna Sharma, Symeon Chatzinotas, Björn Ottersten
Herein, we present a detailed analysis of an eigenvalue based sensing technique in the presence of correlated noise in the context of a Cognitive Radio (CR). We use a Standard Cond…
