1. 1. Over-the-Air Federated Learning with Compressed Sensing

   Master-uppsats, Linköpings universitet/Kommunikationssystem

   Författare :Adrian Edin; [2023]
   Nyckelord :machine learning; ML; Federated Learning; FL; Over-the-air; Over-the-air computation; OtA; OtA computation; AirComp; Compressed sensing; CS; Iterative Hard thresholding; IHT;

   Sammanfattning : The rapid progress with machine learning (ML) technology has solved previously unsolved problems, but training these ML models requires ever larger datasets and increasing amounts of computational resources. One potential solution is to enable parallelization of the computations and allow local processing of training data in distributed nodes, such as Federated Learning (FL). LÄS MER

3. 2. Direct Signal Interference Suppression and Target Detection for Low-Cost SDR-Based Passive Bistatic Radar

   Master-uppsats, Linköpings universitet/Reglerteknik

   Författare :Oskar Jonsson; [2022]
   Nyckelord :passive radar; ECA; LMS; software-defined radio;

   Sammanfattning : Passive radar is a technology for detection of targets using echoes of existing radio transmitter, such as FM-radio. Since only receivers are needed for operation, a passive radar system has the possibility of being implemented using low-cost hardware. LÄS MER

4. 3. ROP-chain generation using Genetic Programming : GENROP

   Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

   Författare :Jonatan Branting; [2022]
   Nyckelord :return oriented programming; genetic programming; binary exploitation; ROP; GP;

   Sammanfattning : Return Oriented Programming (ROP) is the de-facto technique used to exploit most of today’s native-code vulnerabilities hiding in old and newly developed software alike. By reusing bits and pieces of already existing code (gadgets), ROP can be used to bypass the ever-present Write ⊕ eXecute (W⊕X) security feature, which enforces memory to only be marked as either executable or writable; never both at the same time.

5. 4. Evaluation of the Perceived Speech Quality for G729D and Opus : With Different Network Scenarios and an Implemented VoIP Application

   Master-uppsats, Linköpings universitet/Informationskodning

   Författare :Louise Almér; [2022]
   Nyckelord :Compression; Codec; audio; speech quality; quality of experience;

   Sammanfattning : Communication has always been a vital part of our society, and day-to-day communication is increasingly becoming more digital. VoIP (voice over IP) is used for real-time communication, and to be able to send the information over the internet must the speech be compressed to lower the number of bits needed for transmission.

7. 5. System Model of an Ultra-LowPower Fluorescence Detection Micro-Device

   Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

   Författare :Yuanyuan Xue; [2020]
   Nyckelord :;

   Sammanfattning : This thesis aims to explore the power consumption limits of Complementary Metal-Oxide-Semiconductor (CMOS) fluorescent biosensors that meet the demand, a Matlab-based calculator is designed, in which users can input required system parameters (such as LED power and noise) to observe the minimum power consumption of each basic component and the constraints of the transimpedance amplifier: cut-off frequency, signal- to-noise ratio, dynamic range, etc. Thereby to provide a reference range for the next level designs of each component in the detection system.
