11. Beamforming Solutions for Efficient Link Setup and Link Maintenance in mmWave Communication Systems
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : Millimeter wave (mmWave band) technology has gained a lot of attention in 5G communications, due to large amounts of spectrum being available in the mmWave frequency range. However, mmWave links suffer from severe free-space loss and atmospheric absorption. READ MORE

12. Pilot Power Control and Assignment Games in MU-MIMO Systems
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : In this work, we consider a MU-MIMO communication system forboth single cell and multi-cell cases. Other than the fundamental Rayleighchannel model which has been analysed intensively in previous works,we also adopt the Rician channel to model different types of wirelesslinks. READ MORE

13. Control of a Multivariable Lighting System
University essay from Linköpings universitet/ReglerteknikAbstract : This master’s thesis examines how a small MIMO lighting system can be identified and controlled. Two approaches are examined and compared; the first approach is a dynamic model using state space representation, where the system identification technique is Recursive Least Square, RLS, and the controller is an LQG controller; the second approach is a static model derived from the physical properties of light and a feedback feed-forward controller consisting of a PI controller coupled with a Control Allocation, CA, technique.

14. Energy Efficiency of Radio Units and its Impact on RAN Energy Consumption
University essay from Lunds universitet/Avdelningen för Biomedicinsk teknikAbstract : As mobile telecommunications networks continue to grow, energy consumption continues to grow with it. This will without a doubt affect both the operational expense for network operators and the environment due to air pollution from power stations. READ MORE

15. Black-Box Modeling and Attitude Control of a Quadcopter
University essay from Linköpings universitet/ReglerteknikAbstract : In this thesis, black-box models describing the quadcopter system dynamics for attitude control have been estimated using closed-loop data. A quadcopter is a naturally unstable multiple input multiple output (MIMO) system and is therefore an interesting platform to test and evaluate ideas in system identification and control theory on.
