1. 16. Simulating Broadband Analog Aggregation for Federated Learning

   Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Linus Pekkanen; Patrik Johansson; [2020]
   Nyckelord :Federated learning; over-the-air computation; broadband analog aggregation;

   Sammanfattning : With increasing amounts of data coming fromconnecting progressively more devices, new machine learningmodels have risen. For wireless networks the idea of using adistributed approach to machine learning has gained increasingpopularity, where all nodes in the network participate in creatinga global machine learning model by training with the localdata stored at each node, an example of this approach is calledfederated learning.

3. 17. Design and Development of a CubeSat Hardware Architecture with COTS MPSoC using Radiation Mitigation Techniques

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Siddarth Vasudevan; [2020]
   Nyckelord :Commercial Off-The-Shelf Multi-Processor System on Chip; Single-Event Upset; Single-Event Latch-up; Cyclic Redundancy Check; Scrubbing; Radiation hardened Micro-Controller Unit; Soft Error Mitigation-Intellectual Property controller; Error Injection; Space packet protocol; NOR Flash; Magnetoresistive RAM;

   Sammanfattning : CubeSat missions needs components that are tolerant against the radiation in space. The hardware components must be reliable, and it must not compromise the functionality on-board during the mission. At the same time, the cost of hardware and its development should not be high.

4. 18. Watermarking in Audio using Deep Learning

   Master-uppsats, Linköpings universitet/Datorseende

   Författare :Lukas Tegendal; [2019]
   Nyckelord :Machine Learning; Deep Learning; Watermarking;

   Sammanfattning : Watermarking is a technique used to used to mark the ownership in media such as audio or images by embedding a watermark, e.g. copyrights information, into the media. A good watermarking method should perform this embedding without affecting the quality of the media. LÄS MER

5. 19. Investigate Redundancy In Sounding Reference Signal Based Channel Estimates

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

   Författare :Nishanth Bhavani Sankar; Akshay Thakaramkunnath Ajayakumar; [2019]
   Nyckelord :Sounding Reference Signals; Multiple Input Multiple Output; 5th Generation; Time Division Duplexing; Lossless compression; Lossy Compression; Technology and Engineering;

   Sammanfattning : 5G supports enormous increase in data rate. Massive antenna beamforming is expected to play a key role in increasing capacity in case of multi-user MIMO and coverage in case of single-user MIMO. LÄS MER

7. 20. Implementation and Benchmarking of a Crypto Processor for a NB-IoT SoC Platform

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

   Författare :Sébastien Fuhrmann; Luis Cavo; [2018]
   Nyckelord :3GPP; IoT; HLS; security; cryptography; AES; SNOW; ZUC; hardware; ASIC; confidentiality; integrity; cipher; Technology and Engineering;

   Sammanfattning : The goal of this Master’s Thesis is to investigate the implementation of cryptographic algorithms for IoT and how these encryption systems can be integrated in a NarrowBand IoT platform. Following 3rd Generation Partnership Project (3GPP) specifications, the Evolved Packet System (EPS) Encryption Algorithms (EEA) and EPS Integrity Algorithms (EIA) have been implemented and tested.
