Radiocommunication Division activity concerns radiocommunication systems, signal processing, antenna system technology and measurements in radiocommunication. Works and researches carried out in the division cover both advanced theoretical problems and realisation of systems and devices.
The teaching activities of the Radiocommunications Division are related to radiocommunication systems, antennae, signal processing, measurement in radiocommunications, and networks.
Research is focused on digital radio transmission problems and advanced computer science applications, radio systems design, particularly cellular and short range systems, radio transmitting and receiving, as well as ecological, medical and EMC problems. Current research topics include:
- radio-communication systems and networks
-
- 2G (GSM), 3G (UMTS) and 4G (MBS) mobile systems, short range ISM systems (e.g. Bluetooth), Radio Frequency Identity Devices (RFID), ad-hoc networks, satellite systems, radio navigation systems, broadband access networks (LMDS, WLAN) and ultra wideband systems (UWB);
- antennae and radio waves propagation
-
- complex, intelligent antennae and control algorithms;
- scanning antennae, automatic measurements of near zone antenna characteristics, propagation channel modelling;
-
radio communication measurements
- radio spectrum monitoring methods and systems; radio devices testing methods and systems; measurements automation;
-
radio frequency power devices
- class D, DE, E and C resonant power amplifiers, linear wide-band short-wave amplifiers, low-noise amplifiers, microwave filters and phase shifters;
-
a theory of signals and modulations
- multidimensional Hilbert transform and it’s applications, using time-division to frequency division transformations for radio-frequency signal processing;
-
advanced numerical methods
- circuits and systems design and optimisation;
-
environmental and biological problems
- an influence of radio communication systems on a human’s health and environment as well as on electronic equipment, protection zones planning.
