He was a member of the IEEE Signal Processing Society Awards Board during 2017-2019, and a member of the IEEE Signal Processing Magazine editorial board during 2018-2022.

He received the IEEE Signal Processing Magazine Best Column Award twice, in 2012 and 2014, the IEEE ComSoc Stephen O. Rice Prize in Communications Theory in 2015, the IEEE ComSoc Leonard G. Abraham prize in 2017, the IEEE ComSoc Best Tutorial Paper Award in 2018, and the IEEE ComSoc Fred W. Ellersick Prize in 2019. He is a Fellow of the IEEE, and a member of the Royal Swedish Academy of Sciences (KVA).

He won the 2021 "gyllene moroten" (golden carrot) best teacher award from LinTek, the Engineering College student union at LiU.

Illustration RadioWeaves - The emerging physical-layer infrastructure for 6G wireless communications

RadioWeaves – physical-layer infrastructure for 6G wireless communication

RadioWeaves is an emerging physical-layer wireless access infrastructure, in which a fabric of distributed radio devices and computing resources serve as a massive distributed antenna array.

Resource Allocation and Energy Efficiency in Wireless Networks

The demand for wireless data traffic increases exponentially. To keep up with the growth, an ambitious but necessary goal for the next generation wireless networks is to deliver 1000x higher data rates per km2 than today.

Energy-Efficient Digital Signal Processing

Energy efficiency in signal processing hardware is vital for several reasons, in particular to reduce the environmental impact, to increase stand-by times, to make batteries smaller and lighter, and to simplify the cooling of circuits.

Physical layer security in massive MIMO

The inherent openness of the wireless channel makes wireless communication between two legitimate parties susceptible to attacks from a third party, the adversary. These attacks can be divided into two classes: eavesdropping and jamming.

Popular science description of the activities at Communication Systems

Today's society relies more and more on fast and secure communications infrastructure. This is a trend that will continue. Information technology, and especially perhaps mobile communications, has changed people's lives.
