  1. 16. Block Diagonalization Based Beamforming

    University essay from KTH/Teknisk informationsvetenskap

    Author : Darshan Patil; [2017]
    Keywords : ;

    Abstract : With increasing mobile penetration multi-user multi-antenna wireless communication systems are needed. This is to ensure higher per-user data rates along with higher system capacities by exploiting the excess degree of freedom due to additional antennas at the receiver with spatial multiplexing.

  3. 17. Machine Learning for Beam Based Mobility Optimization in NR

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Björn Ekman; [2017]
    Keywords : machine learning; 5G; random forest; multi-class classification; multi-target regression;

    Abstract : One option for enabling mobility between 5G nodes is to use a set of area-fixed reference beams in the downlink direction from each node. To save power these reference beams should be turned on only on demand, i.e. only if a mobile needs it. READ MORE

  4. 18. Precision Closed-Loop Laser Pointing System for the Nanosatellite Optical Downlink Experiment

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Ondrej Čierny; [2017]
    Keywords : ;

    Abstract : The use of advanced small-satellite platforms has become increasingly more popular in the recent years. Several private companies are investing enormous capital into constellations of small satellites that are designed to provide highly data-intensive global services, such as rapid Earth imaging or fast worldwide Internet access.

  5. 19. Unlicensed and licensed low-power wide area networks : Exploring the candidates for massive IoT

    University essay from KTH/Radio Systems Laboratory (RS Lab)

    Author : Daniel Sjöström; [2017]
    Keywords : LPWA; LPWAN; IoT; massive IoT; NB-IoT; eMTC; EC-GSM-IoT; SigFox; LoRa; LoRaWAN; LoRa Alliance;

    Abstract : In the Internet of things (IoT), many applications will require low-power and low-cost to achieve long lifetime and scale (respectively). These types of applications are referred to as massive IoT, as opposed to critical IoT, which emphasizes ultra-high reliability and availability and low latency. READ MORE

  6. 20. Performance of In-Band Full-Duplex for 5G Wireless Networks

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Osama Al-Saadeh; [2016]
    Keywords : Wireless networks; In-band full duplex; Static-time division duplexing; Dynamic-time division duplexing; Interference mitigation techniques; small cell; 5G; mmWave bands; Beamforming; Interference cancellation.; Trådlösa nätverk; Inomband hel duplex; Statisk tidsdelning; Dynamisk tidsdelning; Störningsundertryckningsmetoder; Små celler; 5G; Millimetervågsfrekvenser; Lobformning; Störningseliminering.;

    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.
