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 Multiuser Interference in Symbol Level Precoding for the MISO Downlink Channel
Maha Alodeh, Symeon Chatzinotas, Björn Ottersten
This paper investigates the problem of interference among the simultaneous multiuser transmissions in the downlink of multiple antennas systems. Using symbol level precoding, a new…
Weighted Fair Multicast Multigroup Beamforming under Per-antenna Power Constraints
Dimitrios Christopoulos, Symeon Chatzinotas, Bjorn Ottersten
A multi-antenna transmitter that conveys independent sets of common data to distinct groups of users is considered. This model is known as physical layer multicasting to multiple c…
Information and Energy Cooperation in Cognitive Radio Networks
Gan Zheng, Zuleita Ho, Eduard A. Jorswieck +1
Cooperation between the primary and secondary systems can improve the spectrum efficiency in cognitive radio networks. The key idea is that the secondary system helps to boost the…
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…
