  1. 11. Beamforming Solutions for Efficient Link Setup and Link Maintenance in mmWave Communication Systems

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Hesham Sharkas; Haruhi Echigo; [2019]
    Keywords : 5G; Beamforming; Beam-forming; Beam Management; Beam Searching; Beam Sweeping; Codebook; code-book; Initial Access; MIMO; MillimeterWave; millimeter wave; mmWave; mm-Wave; mm Wave; Precoding; Slepian Beam; Synthesizer; Beam Synthesizer; Technology and Engineering;

    Abstract : Millimeter wave (mmWave band) technology has gained a lot of attention in 5G communications, due to large amounts of spectrum being available in the mmWave frequency range. However, mmWave links suffer from severe free-space loss and atmospheric absorption. READ MORE

    University essay from Uppsala universitet/Signaler och System

    Author : Sebastian Vestberg; [2018]
    Keywords : Propagation modeling; Network Simulations; LTE;

    Abstract : Maps of chosen areas in Chicago, San José, London and Shibuya, areimported from Open Street Map into matlab in order to run LTE networksimulations for various scenarios. Firstly, two path loss models arecompared, the empirically based WINNER model and a set of sitespecificmodel. READ MORE

  4. 13. Deep Learning for Error Prediction In MIMO-OFDM system With Maximum Likelihood Detector

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Baoqing She; [2018]
    Keywords : MIMO-OFDM; CRC; BLER; Detector; SINR; MCS Selection; Link Adaptation; Deep Learning; Neural Networks;

    Abstract : To increase link throughput in multi-input multi-output (MIMO) orthogonal frequencydivision multiplexing (OFDM) systems, transmission parameters such as code rate andmodulation order are required to be set adaptively. Therefore, block error rate (BLER)becomes a crucial measure which illustrates the quality of the link, thus being used in LinkAdaptation (LA) to determine the transmission parameters. READ MORE

  5. 14. The Impact of Antennas on Radiolink Performance in Frequency Hopping Scenarios

    University essay from Uppsala universitet/Signaler och System

    Author : Sofia Bergström; [2018]
    Keywords : ;

    Abstract : This paper investigates how the communication performance of frequency hopping systems are affected by the antenna parameters. The data are generated from Antenna Toolbox in Matlab for the case of two dipole antennas is free space. READ MORE

  6. 15. Scheduler Algorithms for MU-MIMO

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Wissam Moustafa; Richard Mugisha; [2017]
    Keywords : Scheduling; Beamforming; TDD; TM-8; SRS; Downlink; Round Robin; SU-MIMO; MU-MIMO.; Technology and Engineering;

    Abstract : In multi-user multiple input multiple output (MU-MIMO), the complexity of the base-station scheduler has increased further compared to single-user multiple input multiple output (SU-MIMO). The scheduler must understand if several users can be spatially multiplexed in the same time-frequency resource. READ MORE
