1. Design of a grating lobe mitigated antenna array architecture integrated with low loss PCB filtering structures
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Massive multiple input multiple output - MIMO systems are a reality and modern communication systems rely upon this technology to cope with the increasing need for capacity and network usage. Antenna arrays are at the heart of the of the massive-MIMO system and are the enabling technology. READ MORE

2. Adaptive Frequency Resolution for Downlink Beamforming in 5G NR
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : As the demand for higher data rates and lower latencies increase, together with the use of higher frequency bands, MIMO and beamforming have become an essential part of the 5G NR technology. Calculating the beamforming weights is a costly process, and reducing the frequency resolution of the weight calculations would save a significant amount of computational power. READ MORE

3. Performance evaluation of direct air-to-ground communication using new radio (5G)
University essay from KTH/Teknisk informationsvetenskapAbstract : Providing mobile broadband (MBB) coverage to passengers in planes (and other yingobjects) has been one of the very important requirements by airline industry for sometime. With the emergence of high-capacity wireless network concepts, there is a renewedeort in dening systems based on 5G (also dened as NR, new radio) for air-to-ground(A2G) communication. READ MORE

4. Performance of In-Band Full-Duplex for 5G Wireless Networks
University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)Abstract : In-band full duplex is a new duplexing scheme that allows radio nodes to transmit and receive, utilizing the same frequency and time resources. The implementation of in-band full duplex was not feasible in practice, due to the effect of self-interference. But then, advances in signal processing made it possible to reduce this effect.

5. Beam-Forming-Aware Link-Adaptation for Differential Beam-Forming in an LTE FDD System
University essay from Linköpings universitet/KommunikationssystemAbstract : The ability for base stations to be able to beam-form their signals, directing the signal energy to specific users, is a topic of research that has been heavily studied during the last decades. The beam-forming technique aims to increase the signal-to-interference-and-noise-ratio of the user and, consequently, increase the capacity and coverage of the communication system. READ MORE
