1. 1. Approach for frequency response-calibration for microphone arrays

   University essay from KTH/Hälsoinformatik och logistik

   Author : Jacob Drotz; [2023]
   Keywords : microphone array; frequency response; calibration; sine sweep; inverse filter; digital signal processing DSP ; convolution; Fast Fourier Transform FFT ; Discrete Fourier Transform DFT ; acoustic measurements; audio engineering; mikrofonarray; frekvenssvar; kalibrering; sinussvep; inverterat filter; digital signalbehandling; faltning; Fast Fourier Transform FFT ; Discrete Fourier Transform DFT ; akustiska mätningar; ljudteknik;

   Abstract : Matched frequency responses are a fundamental starting point for a variety ofimplementations for microphone arrays. In this report, two methods for frequencyresponse-calibration of a pre-assembled microphone array are presented andevaluated. READ MORE

3. 2. Measurements, Estimations and Calibration with a Fully Digital Array

   University essay from Uppsala universitet/Signaler och system

   Author : Oscar Magnér; [2023]
   Keywords : WiDAR; signal processing; digital array; broadband antenna; array antenna; antenna; calibration; direct sampling; antenn; bredbandig; digital array; array antenn; direktsampling; signalbehandling; kalibrering; WiDAR; Saab AB; SAAB;

   Abstract : In modern digital communication, transmission and reception of information through electromagnetic signals requires digital devices that can process high data rates accurately despite being located in information heavy environments. One type of antenna receiver is the digital antenna array, which can steer its lobes electronically to increase or decrease sensitivity in specific directions. READ MORE

4. 3. Arbitrary motion Synthetic Aperture Radar

   University essay from Lunds universitet/Matematisk statistik

   Author : Filip Alberius; Erik Rolander; [2023]
   Keywords : RADAR; SAR; Synthetic Aperture Radar; Pulsed Coherent Radar; PCR; VR; Virtual Reality; IMU; Inertial Measurment Unit; VAA; Virtual Antenna Array; Obstacle detection; Signal Processing; Matched Filter Method.; Technology and Engineering;

   Abstract : Syftet med denna avhandling är att utveckla en ny metod för att producera bilder med syntetisk aperturradar (SAR), med utgångspunkt i scenarier med arbiträr rörelse vad gäller radarsensorn. SAR är en väletablerad metod för att skapa 2- eller 3-dimensionella radarbilder, som traditionellt sett antar att radar-sensorns rörelse är linjär och förutsägbar. READ MORE

5. 4. Straight to the Heart : Classification of Multi-Channel ECG-signals using MiniROCKET

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

   Author : Stefan Christiansson; [2023]
   Keywords : MiniROCKET; Time-series analysis; Multi-variate; Classification; Convolutional Neural Network; MiniROCKET; Tidsserieanalys; Multivariat; Klassifikation; Convolutional Neural Network;

   Abstract : Machine Learning (ML) has revolutionized various domains, with biomedicine standing out as a major beneficiary. In the realm of biomedicine, Convolutional Neural Networks (CNNs) have notably played a pivotal role since their inception, particularly in applications such as time-series classification. READ MORE

6. 5. High Level Synthesis for ASIC and FPGA

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

   Author : Malin Heyden; [2023]
   Keywords : HLS; high level synthesis; asic; fpga; catapult; filter; sfir; Technology and Engineering;

   Abstract : This thesis aims to evaluate the performance of Siemens’ High Level Synthesis (HLS) tool Catapult. HLS can be considered the next step up in abstraction level from writing traditional Register Transfer Level (RTL) code which is time consuming and error prone. READ MORE
