Wireless Terahertz System Architectures for Networks Beyond 5G
Alexandros-Apostolos A. Boulogeorgos, Angeliki Alexiou, Dimitrios Kritharidis +15
The present white paper focuses on the system requirements of TERRANOVA. Initially details the key use cases for the TERRANOVA technology and presents the description of the networ…
Energy Efficiency Fairness for Multi-Pair Wireless-Powered Relaying Systems
Kien-Giang Nguyen, Quang-Doanh Vu, Le-Nam Tran +1
We consider a multi-pair amplify-and-forward relay network where the energy-constrained relays adopting time-switching protocol harvest energy from the radio frequency signals tran…
Energy Efficiency Maximization for C-RANs: Discrete Monotonic Optimization, Penalty, and l0-Approximation Methods
Kien-Giang Nguyen, Quang-Doanh Vu, Markku Juntti +1
We study downlink of multiantenna cloud radio access networks (C-RANs) with finite-capacity fronthaul links. The aim is to propose joint designs of beamforming and remote radio hea…
Energy-Efficient Multi-Cell Multigroup Multicasting with Joint Beamforming and Antenna Selection
Oskari Tervo, Le-Nam Tran, Harri Pennanen +3
This paper studies the energy efficiency and sum rate trade-off for coordinated beamforming in multi-cell multi-user multigroup multicast multiple-input single-output systems. We f…
Terahertz Technologies to Deliver Optical Network Quality of Experience in Wireless Systems Beyond 5G
Alexandros-Apostolos A. Boulogeorgos, Angeliki Alexiou, Thomas Merkle +11
This article discusses the basic system architecture for terahertz (THz) wireless links with bandwidths of more than 50 GHz into optical networks. New design principles and breakth…
Low Complexity Time Domain Semi-Blind MIMO-OFDM Channel Estimation Using Adaptive Bussgang Algorithm
Ebrahim Karami, Markku Juntti
In this paper, a low complexity time domain semi-blind algorithm is proposed to estimate and track the time varying MIMO OFDM channels. First, the proposed least mean squares (LMS)…
