1. Single-User Receivers for Partly Known Interference in Multi-User Environments
Sammanfattning : In multiuser environments such as cellular radio systems, the limited available bandwidth is one of the principal design constraints. For future high subscriber density systems, frequency reuse is one of the fundamental approaches for efficient spectrum utilization in order to meet the increased demands for capacity. LÄS MER
2. Interference Rejection in Wireless Communication Systems
Sammanfattning : This thesis is concerned with the problem of interference rejection in wireless communication systems. Different solutions are proposed, depending on the type of system under study and the amount of knowledge available about the signal and the propagation environment. LÄS MER
3. Coordinated Transmission for Wireless Interference Networks
Sammanfattning : Wireless interference networks refer to communication systems in which multiple source–destination pairs share the same transmission medium, and each source’s transmission interferes with the reception at non-intended destinations. Optimizing the transmission of each source–destination pair is interrelated with that of the other pairs, and characterizing the performance limits of these networks is a challenging task. LÄS MER
4. Cooperative communication for multi-user cognitive radio networks
Sammanfattning : In recent years, the main trend in wireless communications has been shifted from voice transmission to data-centric communication. This shift has caused an increase in the data rate requirements for future wireless communication systems. These requirements result in need for large bandwidth. LÄS MER
5. Doctoral Thesis: Massive MIMO in Real Propagation Environments
Sammanfattning : Mobile communications are now evolving towards the fifth generation (5G). In the near future, we expect an explosive increase in the number of connected devices, such as phones, tablets, sensors, connected vehicles and so on. Much higher data rates than in today's 4G systems are required. LÄS MER
