1. 1. Digital Front End Algorithms for Sub-Band Full Duplex

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

   Författare :Midhat Rizvi; Khaled Al-Khateeb; [2023]
   Nyckelord :Adjacent Channel Leakage Ratio; Bit Error Rate; Clipping and Filtering; Crest Factor Reduction; Digital front end; Digital Pre-Distortion Error Vector Magnitude; Frequency Division Duplex; Power Amplifier; Peak to Average Power Ratio; Peak Cancellation Crest Factor Reduction; Sub Band Full Duplex; Self-Interference Cancellation; Signal-to-Interference Noise Ratio; Signal-to-Noise Ratio; Turbo Clipping; Time Division Duplex; Technology and Engineering;

   Sammanfattning : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

3. 2. A General Purpose Near Data Processing Architecture Optimized for Data-intensive Applications

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

   Författare :Xingda Li; Haidi Hu; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : In recent years, as Internet of Things (IoT) and machine learning technologies have advanced, there has been increasing interest in the study of energy-efficient and flexible architectures for embedded systems. To bridge the performance gap between microprocessors and memory systems, Near-Data Processing (NDP) was introduced. LÄS MER

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

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

   Författare :Oscar Magnér; [2023]
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

5. 4. Evaluation of deep learning image reconstruction for brain- and abdominal CT - A visual grading characteristics study

   Master-uppsats,

   Författare :Tuva Skarp; [2022-05-04]
   Nyckelord :Medical physics; CT; Computed tomography; imaging; Deep learning image reconstruction;

   Sammanfattning : Computed tomography (CT) is a common medical imaging method today. There are different ways of reconstructing the images from a CT examination. The standard method is the filtered back projection (FBP). LÄS MER

7. 5. Organization of Electronic Dance Music by Dimensionality Reduction

   Master-uppsats, Umeå universitet/Institutionen för datavetenskap

   Författare :Victor Tideman; [2022]
   Nyckelord :Dimensionality Reduction; Digital Signal Processing; Similarity; Music;

   Sammanfattning : This thesis aims to produce a similarity metric for tracks of the genre: Electronic Dance Music, by taking a high-dimensional data representation of each track and then project it to a low-dimensional embedded space (2D and 3D) by applying two Dimensionality Reduction (DR) techniques called t-distributed stochastic neighbor embedding (t-SNE) and Pairwise Controlled Manifold Approximation (PaCMAP). A content-based approach is taken to identify similarity, which is defined as the distances between points in the embedded space. LÄS MER
