  1. 1. Managing Radio and Energy Resources in LTE-Based Military Training Networks

    Author : Hawar Ramazanali; Alexey Vinel; Magnus Jonsson; Dmitry Petrov; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 4G; 5G; LTE; DRX;

    Abstract : The number of wireless connected devices are growing exponentially and the importance of this research area is growing as well to meet the known and looming challenges and expectations. The 5:th Generation telecommunications standard is partly embodied by the Machine-to-Machine (M2M) and Internet of Things (IoT) technologies and standards to handle a big part of these devices and connections.

  3. 3. Multi-Band Multi-Standard CMOS Receiver Front-Ends for 4G Mobile Applications

    Author : Saul Alejandro Rodriguez Duenas; Ana Rusu; Mohammed Ismail El-Naggar; Erik Bruun; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; LNA; mixer; 4G; Electronics; Elektronik;

    Abstract : The development of the transistor and its continuous down-scaling has allowed during the last decades the appearance of cheap wireless communication systems targeting consumer products. The complexity of these systems has increased dramatically during the last years, mainly fueled by both the Moore law and improvements in communication theory. READ MORE

  4. 4. Doctoral Thesis: Massive MIMO in Real Propagation Environments

    Author : Xiang Gao; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Massive MIMO; very-large MIMO; multi-user MIMO; channel measurements; channel modeling; 5G; sum-rate capacity; antenna selection; signal processing;

    Abstract : Mobile communications are now evolving towards the fifth generation (5G). In the near future, we expect an explosive increase in the number of connected devices, such as phones, tablets, sensors, connected vehicles and so on. Much higher data rates than in today's 4G systems are required. READ MORE

  5. 5. From Orthogonal to Non-orthogonal Multiple Access : Energy- and Spectrum-Efficient Resource Allocation
