Microwave and optical telecommunication systems

Activity of the research group:

Wave propagation, systems engineering and physical layer aspects of bulk antenna techniques. Investigation of massive MIMO systems. Cognitive radio, modulation techniques for opportunistic spectrum usage, signal processing issues, software radio applications. Validation of electromagnetic field computation models for radio devices. Modulation, coding and synchronisation issues in satellite communications. DRM30 and UHF DVB coverage optimisation.

Recent results:

• Development of the DSP part of the ground station for the Alphasat satellite reception experiments
• Development of telemetry for SMOG-P/SMOG-1/ATL-1 satellites, reception software
• DARPA Spectrum Collaboration Challenge results
• Participation in the development of the IEEE/IEC 62704 standard
• Optimisation of the Hungarian DVB-T2 network (with Antenna Hungária)
