1. Beyond Massive MIMO : Trade-offs and Opportunities with Large Multi-Antenna Systems
Sammanfattning : After the commercial emergence of 5G, the research community is already putting its focus on proposing innovative solutions to enable the upcoming 6G. One important lesson put forth by 5G research was that scaling up the conventional multiple-input-multiple-output (MIMO) technology by increasing the number of antennas could be extremely beneficial for effectively multiplexing data streams in the spatial domain.

2. Social Networks and Privacy
Sammanfattning : Centralized online social networks pose a threat to their users’ privacy as social network providers have unlimited access to users’ data. Decentralized social networks address this problem by getting rid of the provider and giving control to the users themselves, meaning that only the end-users themselves should be able to control access of other parties to their data.

3. Study on Decentralized Machine Learning and Applications to Wireless Caching Networks
Sammanfattning : To promote the development of distributed machine learning, it is crucial to provide efficient models and training algorithms. This thesis is devoted to the design of distributed multi-task learning and decentralized algorithms, as well as the application of distributed machine learning in wireless caching networks. LÄS MER
4. Planning and Control of Uncertain Cooperative Mobile Manipulator-Endowed Systems under Temporal Logic Tasks
Sammanfattning : Control and planning of multi-agent systems is an active and increasingly studied topic of research, with many practical applications such as rescue missions, security, surveillance, and transportation. This thesis addresses the planning and control of multi-agent systems under temporal logic tasks. LÄS MER
5. Security and trust mechanisms for groups in distributed services
Sammanfattning : Group communication is a fundamental paradigm in modem distributed services, with applications in domains such as content distribution, distributed games, and collaborative workspaces. Despite the increasing interest in group-based services and the latest developments in efficient and reliable multi cast, the secure management of groups remains a major challenge for group communication.
