Linearizing Active Antenna Arrays: Method and Measurements
Alberto Brihuega, Mahmoud Abdelaziz, Matias Turunen +3
In this paper, we provide a novel framework for efficient digital predistortion (DPD) based linearization of active antenna arrays with multiple and mutually different nonlinear po…
Positioning and Location-Aware Communications for Modern Railways with 5G New Radio
Jukka Talvitie, Toni Levanen, Mike Koivisto +3
Providing high-capacity radio connectivity for high-speed trains (HSTs) is one of the most important use cases of emerging 5G New Radio (NR) networks. In this article, we show that…
Energy Efficiency Maximization of Full-Duplex Two-Way Relay With Non-Ideal Power Amplifiers and Non-Negligible Circuit Power
Qimei Cui, Yuhao Zhang, Wei Ni +2
In this paper, we maximize the energy efficiency (EE) of full-duplex (FD) two-way relay (TWR) systems under non-ideal power amplifiers (PAs) and non-negligible transmission-depende…
Efficient Fast-Convolution-Based Waveform Processing for 5G Physical Layer
Juha Yli-Kaakinen, Toni Levanen, Sami Valkonen +4
This paper investigates the application of fast-convolution (FC) filtering schemes for flexible and effective waveform generation and processing in the fifth generation (5G) system…
Sum-Rate Analysis and Optimization of Self-Backhauling Based Full-Duplex Radio Access System
Dani Korpi, Taneli Riihonen, Ashutosh Sabharwal +1
In this article, a radio access system with a self-backhauling full-duplex access node serving legacy half-duplex mobile devices is studied and analyzed. In particular, it is assum…
Exact Error Analysis and Energy-Efficiency Optimization of Regenerative Relay Systems with Spatial Correlation
Mulugeta K. Fikadu, Paschalis C. Sofotasios, Qimei Cui +2
Energy efficiency and its optimization constitute critical tasks in the design of low-power wireless networks. The present work is devoted to the error rate analysis and energy-eff…
