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

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

    Author : Midhat Rizvi; Khaled Al-Khateeb; [2023]
    Keywords : 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;

    Abstract : 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. Simulation and Testing of a MU-MIMO Beamforming System

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

    Author : Nazyar Mehdishishavan; Zonghan Wang; [2023]
    Keywords : Multi-User Multiple-Input Multiple-Output MU-MIMO ; Beamforming; Sounding Reference Signal SRS ; Reciprocity-based; Butler matrix; Advanced Antenna System AAS ; Technology and Engineering;

    Abstract : Multi-User Multiple-Input Multiple-Output (MU-MIMO) technology has become increasingly important in the field of wireless communication due to its ability to highly increase the capacity and efficiency of wireless networks [1]. Beamforming, as a technique used in MU-MIMO systems, improves network performance by improving signal quality and reducing interference. READ MORE

  4. 3. FFS: A cryptographic cloud-based deniable filesystem through exploitation of online web services : Store your sensitive data in plain sight

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

    Author : Glenn Olsson; [2023]
    Keywords : Filesystem; Fejk FileSystem; Cloud-based filesystem; Steganograhpic filesystem; Filsystem; Fejk FileSystem; Molnbaserat filsystem; Steganografiskt filsystem;

    Abstract : Many Online Web Services (OWSs) today, such as Flickr and Twitter, provide users with the possibility to post images that are stored on the platform for free. This thesis explores creating a cryptographically secure filesystem that stores its data on an online web service by encoding the encrypted data as images. READ MORE

  5. 4. Convolutional-LSTM for IGBTs Prognostics and Age Monitoring : Designing a neural network for predicting aging precursors in power devices

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

    Author : Matteo Santoro; [2023]
    Keywords : Neural Networks; Igbt; Prognostics; Age Monitoring; Neurala Nätverk; Igbt; Prognostik; Övervakning av Ålder;

    Abstract : In recent years, extensive research efforts have been dedicated to the field of prognostics and age-related degradation, with major focus on higher complexity devices. However, relatively little attention has been given to power devices, such as Insulated Bipolar Gate Transistors (IGBTs), despite their critical role in high power electronic applications. READ MORE

  6. 5. Modeling and Control of a PMSM Operating in Low Speeds

    University essay from Linköpings universitet/Fordonssystem

    Author : Robin Helsing; Tobias Sanchez; [2022]
    Keywords : PMSM; BLDC; low speed; EKF; UKF; MPC; Extended Kalman Filter; Unscented Kalman Filter; PI; Control; FOC;

    Abstract : A permanent magnet synchronous motor is a type of motor that is used in several different application areas, not least in an autonomous robots where it is the motor that drives the wheels. Today, many actors choose simulation as a tool to save money and time when product tests are performed. READ MORE
