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.
