Description of research
Project consists of the development of new methods and algorithms, derivation of theoretical results, experimental verification, and development of systems for more efficient usage of computer and communication systems, with the focus on performance and to consume less energy. The topic belongs to Green technologies, and the focus is on consuming less energy or to reduce contamination and waste materials of computer and communication systems. Research is on efficient algorithms for signal and data processing, mathematical modeling, efficient spectral usage, optimization of computer systems, and usage of reconfigurable systems. The results will be used in communication systems, wireless communication, image and speech processing, and business decisions. Commercial software solutions will be produced, new or as upgrade of existing, or as part of equipments and systems produced by our participants.
Signal processing, computer systems, mathematical modelling.
The expected results of this project are (1) the selection of modules and smaller units as parts of larger systems, (2) new methods, algorithms, and software solutions based on recent achievements of researchers employed by this project (modeling of analog passive systems implemented using digital systems, digital filters, nonlinear time-discrete systems). A part of team will work on theoretical-experimental research activities in the field of wireless communications. The main topic of research will be also on efficient reconfigurable filters, optimization algorithms, and implementation of efficient filters.
Another research topic is application of data selection and compression for building energy-efficient communication and information systems. This topic is a new area in signal processing with a wide possibility in building energy-efficient communication and information systems. The basic idea is on non-uniform sampling, with a limited number of data in such a way that it has all accurate relevant information. The key issue is to derive new efficient algorithms so that the minimal numbers of data contain the whole information without loss. Mathematical methods used in the research will cover liner data-base wavelets and L1 optimization.
