Research in Communication Systems

The division of Communication Systems conducts research on communications engineering, and wireless communications in particular. A basic problem in wireless communications is that the part of the electromagnetic spectrum that is suitable for radio communication is rather small. This part of the spectrum is therefore a limited resource. Another problem is the limited power consumption that mobile electronics can afford. The primary limiting factor is the limited capacity of batteries. Typically, much power is spent on signal processing, for example, extraction of digital information from analog waveforms. New applications will require even more advanced signal processing than today's systems. At the same time, end users will require more mobility and longer battery time. This generates a need for efficient signal processing algorithms which can optimally exploit modern hardware. The research in the division addresses these fundamental problems.
