  1. 1. Watermarking in Audio using Deep Learning

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Lukas Tegendal; [2019]
    Nyckelord :Machine Learning; Deep Learning; Watermarking;

    Sammanfattning : Watermarking is a technique used to used to mark the ownership in media such as audio or images by embedding a watermark, e.g. copyrights information, into the media. A good watermarking method should perform this embedding without affecting the quality of the media. LÄS MER

  2. 2. Investigate Redundancy In Sounding Reference Signal Based Channel Estimates

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Nishanth Bhavani Sankar; Akshay Thakaramkunnath Ajayakumar; [2019]
    Nyckelord :Sounding Reference Signals; Multiple Input Multiple Output; 5th Generation; Time Division Duplexing; Lossless compression; Lossy Compression; Technology and Engineering;

    Sammanfattning : 5G supports enormous increase in data rate. Massive antenna beamforming is expected to play a key role in increasing capacity in case of multi-user MIMO and coverage in case of single-user MIMO. LÄS MER

  3. 3. Implementation and Benchmarking of a Crypto Processor for a NB-IoT SoC Platform

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

  4. 4. Millimeter Wave Antenna Array Calibration and Validation for 5G New Radio Access

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Manuel Jose Lopez Morales; [2018]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This Master thesis work was performed in Ericsson AB, Lund. It studies and validates two classes of algorithms to be used in mm-wave massive MIMO antenna arrays, for their use in the future 5G mobile communication systems. LÄS MER

  5. 5. Security in low power wireless networks : Evaluating and mitigating routing attacks in a reactive, on demand ad-hoc routing protocol

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap; Linköpings universitet/Institutionen för datavetenskap

    Författare :Tony Fredriksson; Niklas Ljungberg; [2017]
    Nyckelord :IoT; Security; Ad-hoc Routing; RIME; Sinkhole; Selective Forwarding; Sybil; Intrusion Detection System;

    Sammanfattning : Using low energy devices to communicate over the air presents many challenges to reach security as resources in the world of Internet Of Things (IoT) are limited. Any extra overhead of computing or radio transmissions that extra security might add affects cost of both increased computing time and energy consumption which are all scarce resources in IoT. LÄS MER
