Research

My current research is on massive MIMO; From channel measurements, characterization and modeling to signal processing. I’m interested in the experimental investigation of the mobile radio channel as well as theoretical studies of channel modeling. I am also interested in using signal processing to exploit the characteristics of the channel to improve the wireless communications.
