  1. 1. Implementation and evaluation of Polar Codes in 5G

    Kandidat-uppsats, Karlstads universitet; Karlstads universitet

    Författare :Tobias Rosenqvist; Joël Sloof; [2019]
    Nyckelord :5G; Polar Codes; Successive Cancellation;

    Sammanfattning : In today’s society the ability to communicate with one another has grown, were a lot of focus is aimed towards speed in the telecommunication industry. For transmissions to become even faster, there are many ways to enhance transmission speeds of which error correction is one. LÄS MER

  2. 2. Improving Spatial Sound Capturing on Mobile Devices Through Fusion of Inertial Measurement Data

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Pouya Ashraf; [2018]
    Nyckelord :;

    Sammanfattning : Through the use of sensor arrays it is possible to extract spatial information about signals present in the environment. For instance position, velocity, distance, etc. LÄS MER

  3. 3. Block Diagonalization Based Beamforming

    Master-uppsats, KTH/Teknisk informationsvetenskap

    Författare :Darshan Patil; [2017]
    Nyckelord :;

    Sammanfattning : 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.

  4. 4. Determination and compensation of magnetic dipole moment inapplication for a scientific nanosatellite mission

    Master-uppsats, KTH/Rymd- och plasmafysik

    Författare :Csaba Jéger; [2017]
    Nyckelord :cubesat; magnetic dipole estimation; attitude dynamics; cubesat; magnetisk dipol uppskattning; attityddynamik;

    Sammanfattning : SEAM (Small Explorer for Advanced Missions) is a 3U CubeSat developedat KTH Royal Institute of Technology which will provide highqualityDC and AC magnetic field measurements of Earth’s magneticfield. The measurement system requires extended periods of timeup to 1000 seconds without active attitude control. LÄS MER

  5. 5. Experimental Implementation of a Fiber Noise Cancellation System for Slow Light Laser Locking

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Partikelfysik

    Författare :Alexander Bengtsson; [2017]
    Nyckelord :Optical Fibers; Fiber Noise Cancellation; Laser Stabilization; Slow Light Laser Locking; Technology and Engineering;

    Sammanfattning : An electromagnetic wave propagating through an optical fiber is sensitive to external disturbances, such as mechanical vibrations and temperature and pressure fluctuations, which add phase noise onto the wave. For high-precision frequency-based applications this phase noise has to be removed. LÄS MER
