Interference-Aware RZF Precoding for Multi Cell Downlink Systems
Axel Müller, Romain Couillet, Emil Björnson +2
Recently, a structure of an optimal linear precoder for multi cell downlink systems has been described in [1, Eq (3.33)]. Other references (e.g., [2,3]) have used simplified versio…
Secrecy Capacity Region of Some Classes of Wiretap Broadcast Channels
Meryem Benammar, Pablo Piantanida
This work investigates the secrecy capacity of the Wiretap Broadcast Channel (WBC) with an external eavesdropper where a source wishes to communicate two private messages over a Br…
Capacity of a Class of State-Dependent Orthogonal Relay Channels
Iñaki Estella Aguerri, Deniz Gündüz
The class of orthogonal relay channels in which the orthogonal channels connecting the source terminal to the relay and the destination, and the relay to the destination, depend on…
Renewable Powered Cellular Networks: Energy Field Modeling and Network Coverage
Kaibin Huang, Marios Kountouris, Victor O. K. Li
Powering radio access networks using renewables, such as wind and solar power, promises dramatic reduction in the network operation cost and the network carbon footprints. However,…
Kernel-Based Adaptive Online Reconstruction of Coverage Maps With Side Information
Martin Kasparick, Renato L. G. Cavalcante, Stefan Valentin +2
In this paper, we address the problem of reconstructing coverage maps from path-loss measurements in cellular networks. We propose and evaluate two kernel-based adaptive online alg…
