  1. 1. The Effect of Distortions Induced by Adaptive Antenna Arrays in GNSS Applications

    University essay from Linköpings universitet/Kommunikationssystem; Linköpings universitet/Tekniska fakulteten

    Author : Emma Beskow; [2022]
    Keywords : GNSS; GPS; Jamming; Beamforming; Adaptive antenna arrays; Frequency response distortions;

    Abstract : Global Navigation Satellite Systems (GNSS) are vital tools for accurate navigation and timing for both civil and military use. Due to the low power of the GNSS signals, these systems are sensitive to interference attacks. For wideband GNSS jamming, adaptive antenna arrays are commonly used to suppress interference.

  3. 2. Development of measurement algorithm in an industrial PLC : An evaluation of DSOGI-PLL for real time measurements

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Caroline Moberg; [2019]
    Keywords : Phase locked loop; DSOGI-PLL; Symmetrical component extraction; Measurement algorithm;

    Abstract : The aim of this project was to devise an algorithm for three phase AC power grid measurements that could be utilized in an excitation system for controlling generators. This application requires fast and accurate measurements even when the voltages in the power grid are characterized by unbalanced three-phase, frequency variations and harmonic distortions.

  4. 3. Design of equalization filter for non-linear distortion of the loudspeaker array with listener's movement

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

    Author : Akshaya Ravi; [2018]
    Keywords : ;

    Abstract : The importance of the real-time virtual auditory environment is dependent on the fidelity of reproducing the sound. The loudspeaker array provided with its ideal response is suitable for the sound reproduction. However, there exists frequency and phase distortions in the loudspeaker response that cause audible artifacts at the listener's ears. READ MORE

  5. 4. RF BiST för att detektera IQ-imbalanser avseende överhörningseffekter för avancerade antennsystem

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

    Author : Kishore Khed; [2018]
    Keywords : Technology and Engineering;

    Abstract : Internet of Things (IoT) is a network constituted by uniquely identifiable commodity objects or devices equipped with some sensing system. To achieve high data rates required for IoT devices, a modern wireless communication system, known as Advanced Antenna Systems(AAS), leads to significant improvement, by increasing not only the data rate but also spectrum efficiency and the channel capacity.
