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.

The unified device for noise-immune transmission in high data rate radio relay and satellite communication channels

Радіорелейна станція широкосмугового доступу

The results of research led to the creation of new types of standardized devices for interference-free data transmission in high-speed channels, microwave and satellite communication, which are the main technical and economic parameters exceed the available foreign analogues.
Unification is implemented as a range of frequencies used for (2 GHz, 5 GHz, 12 GHz, 130 GHz) and by type of radio channel (microwave and satellite).
