Research of scientific and technical basis of communication software-defined radiosystem creation

The work was aiming to develop the scientific and technical bases for the creation of a new generation of software-defined radio systems for telecommunications systems of 4-5 generations, which will be based on the application of new technologies for the construction of radio transceivers, digital signal processing and the organization of effective interaction of system, hardware and application software.

Development of digital modem equipment for next generation tropospheric stations and small satellite radio communication systems

The structural and functional principles of modem equipment construction for over-the-horizon communication were developed. Time adaptation algorithms for changing conditions of over-the-horizon communication station, based on fuzzy conclusion algorithms were developed. Algorithms of frequency adaptation for initialization and continuous operation modes were developed. Algorithms to receive energy estimations of the channel and their statistical parameters were developed.
