I started my PhD in June 2013, after getting my M.Sc degree in Applied Physics and Electrical Engineering with a specialization in applied mathematics (Teknisk matematik), here in Linköping. I did my master thesis, entitled "Obstacle Detection Using an Ultrasonic Method", at Syncore technologies, where we developed a prototype for detecting people in commercial vehicles.
My current research involves different aspects of massive MIMO. In particular, I study how the base station can communicate with terminals/users (e.g. a cell phone) without any knowledge of the propagation channel. In this setting, some of the benefits of massive MIMO (such as efficient beamforming) are nonexistent; thus, we have to resort to another way of conveying information to the users. Specifically, I've analyzed how space-time block codes can be used to increase the reliability of this transmission.
In another project, I've studied jamming and physical layer security in massive MIMO. In particular, I've analyzed how a massive MIMO base station, or any other array with enough antennas, can be used as a jammer to hinder communication between two transceivers.
During the spring of 2018, I've been teaching TSKS14
(Multiple Antenna Communications). Courses I've taught previous years include TSKS01
(Digital Communication), TSKS10
(Signals, Information and Communications), TSKS11
(Networks: Models, Algorithms and Applications), TSKS15
(Detection and Estimation of Signals) and TSDT14
