Innovative signal processing technologies for smart and effective electronic system development.
The objective of the project is development and research of original signal processing technologies, which are oriented towards practical applications to solve actual economic problems and provide the opportunities for manufacture of competitive and knowledge intensive products.
Project includes development of promising signal registration and processing technologies for increased embedded system efficiency (cooperation, energy, performance) and mobility, extremely accurate (picoseconds) timing system construction, ultra wide-band signal generation and super-sensitive detection, biological (including brain) signal processing, sensor network (including vehicular) data transmission, and involves sensor and other contemporary material utilization. To accomplish the objectives, active collaboration with other projects of the program is intended, to utilize their innovations, including new sensors, effective energy harvesting methods, nano-electronic and other materials, and to provide innovative signal processing approach for material-science applications, non-intrusive control and contactless diagnosis of newly created materials.
