Signal processing laboratory

The laboratory was established in 1972 and is engaged in theoretical research and practical development of digital signal processing systems, including the development of specific techniques and applications in analog-to-digital signal conversion. The work of the laboratory during these years is reflected in more than 200 publications, conference presentations, and monographs.

Currently, 21 people are working in the laboratory, including 2 lead researchers, 4 researchers, 7 assistants.

Research and development areas:

  • Virtual instruments based on advanced DSP technologies;
  • Program-controlled radio devices, including those based on non-uniform sampling;
  • Signal-dependent analysis of non-stationary signals, event-driven analog-to-digital conversions;
  • Biometrics and brain signal processing;
  • Microminiaturization of data acquisition and processing systems;
  • Smart sensor and networked embedded system signal processing;
  • Wireless sensor network systems, including sensor module hardware architecture, communication protocols, operating systems and application-oriented software;
  • Applications of directional antenna arrays in wireless sensor networks;
  • Transistor based UWB pulse generators and receivers.

Currently, 2 groups have been formed in the laboratory focusing on the development of wearable sensor systems and the development of ultra-wideband radar technology.

Wearable sensor group is working on wearable sensor system development with potential applications in medicine, sport and daily activities. Mainly systems are based on inertial sensors, but the group has also experience with bioelectric signals (ECG, EMG, EEG). Within group novel wired communication solution has been developed that allows data acquisition from several hundred sensors, using minimal wiring. The solution is further developed beyond the field of wearable sensor systems for monitoring the deformations of constructions.

Examples of developed technologies:

Group competencies-expertise: sensor system development, inertial sensors, low power sensor system development, PCB design, Flexible PCB design, digital communication interfaces, Bluetooth and Bluetooth Low Energy communication in application level, inertial signal processing, bio-electric signal processing, machine learning algorithms, 3D visualization, simulations, software development for smart devices (Android OS smartphones, tablets) in wearable sensor context.
