SIGCOM

The research group focuses on wireless/satellite communications, networking and radar systems and is headed by Profs. Chatzinotas and Ottersten.

The research on communications focuses on the formulation, modeling, design, and analysis of future communication networks that are capable of supporting new services in a cost efficient manner. This includes channel modeling, transceiver design, pre-coding/equalization, interference handling, cognitive techniques, multibeam processing, relaying, MIMO systems, resource management, energy harvesting, physical layer security and network performance. The communication activities are experimentally driven and supported by the SnT Communications Lab, our SW Simulators and our OTA Facilities.

The research on Radar signal processing with applications in the automotive sector is geared towards analysis and development of signal processing techniques for short to mid-range radar sensing and imaging to enhance resolution and localization. Investigations into cognitive radar and their applicability in emerging coexistence scenarios are also being conducted. Spectrum sharing between radar and communications, sparse sensing are also being considered. A hardware testbench implementing a cognitive radar set-up and incorporating the algorithms developed in the group is being considered at SnT Radar Lab.
