The Signal Processing Lab is a world-leading research group on wireless communications, statistical signal processing, measurements, and navigation systems. The group has an outstanding track-record of publications on both basic and applied research with industry collaborations.
Basic research in this unit was assessed as world-leading across the majority of the unit (…) The single strongest aspect of the unit is its world leading research in communication theory and wireless communications.
In the 2008 Research Assessment Exercise, KTH’s research was evaluated by 80 international experts. The different research areas in the Signal Processing lab were all praised for their excellent quality and impact on the academic and industrial world. A few of the comments were:
- “The work in multi-antenna systems for suppressing interference in wireless communications is world leading (the widely used Spatial Division Multiple Access (SDMA) technology was developed and patented here).”
- “The development of a unique-for-academia wireless multi-antenna, multi-node test-bed and associated rapid prototyping capability is outstanding and a critically valuable resource.”
- Measurement techniques ”is a very important area to industry, which has remained unexplored from an academic research viewpoint. The research combines, creatively, techniques from signal processing and microwave engineering.”
