  1. 1. Analysis and Measurement of Key Performance Indicators for MIMO Antennas

    University essay from Umeå universitet/Institutionen för fysik

    Author : Ossian Kynman; [2023]
    Keywords : MIMO; Diversity Gain; Capacity; Correlation; Fading;

    Abstract : Multiple-in multiple-out (MIMO) is a wireless communication technique where antenna arrays, at the receiver and transmitter, utilize signal multipath propagation to increase data throughput capacity. The unique benefits MIMO provides have over the last 20 years led to the steady increase in usage in both Wi-Fi and mobile networks. READ MORE

  3. 2. Far Field Electromagnetic Side Channel Analysis of AES

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

    Author : Zihao Zhao; [2020]
    Keywords : Side-channel analysis; far-feild electromagnetic emission; AES;

    Abstract : Side-Channel Attacks (SCAs) have become a realistic threat to implementations of cryptographic algorithms. By utilizing the unintentionally leaked side-channel information during the execution of a cryptographic algorithm, it is possible to bypass the theoretical strength of the algorithm and extract its secret key.

  4. 3. A Quadrature Frequency Generation Chain for Direct-conversion Phased-array 5G Transceivers

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

    Author : Hamid Yadegar Amin; [2020]
    Keywords : 5G Phased array mm-wave FR2; Technology and Engineering;

    Abstract : The 5th generation (5G) has recently specified a new spectrum range, FR2- 5G New Radio (5G-NR), to provide higher spectral efficiency and channel capacity for ubiquitous cellular connectivity where the user ends can be in various types such as picocell stations, sensor nodes, cloud servers, hand-held devices, and so on. Due to the advantage of phased array antennas in performing beam-forming, and improving SNR at higher spectra, multi-antenna systems have gained an inevitable role in developing such radios.

  5. 4. Improved Accuracy for Indoor Positioning with Bluetooth 5.1: From Theory to Measurements

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

    Author : Victor Sesma Santos; Victor Egorov; [2020]
    Keywords : Technology and Engineering;

    Abstract : In this thesis we are evaluating Bluetooth Low Energy (BLE) v5.1 in combination with Direction Of Arrival (DOA) algorithms and receiving antenna arrays for indoor positioning systems. The thesis is divided in two parts. The first part is the core of the thesis and is composed by the evaluation of DOA algorithms in a direction finding system. READ MORE

  6. 5. Reliable communication in mine environments for autonomous vehicles

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

    Author : Alessandro Tomasi; [2016]
    Keywords : vehicular communication; intelligent transport system; 802.11p; autonomous mining;

    Abstract : Automation in the mining industry has the potential to increase safety and productivity while improving working conditions. Ore transportation within the mine is a repetitive task which is well suited to be replaced by an autonomous mining vehicle operating around the clock. READ MORE
