The group of young scientists was awarded prizes from NAS of Ukraine for achievements in the development of important scientific problems. Among prizemen, Sergey Osypchuk, who is a representative of the Kiev Polytechnic, Ph.D. and teaching assistant at the Department of Telecommunication Systems in ITS.

In his scientific work about cordless communication system the scientist studied the ways of improvement of the informational efficiency of cordless transmitting systems with exploitation OFDM mode on the base of link channel resource leveling that is put on the action through coding class LDPC, which is tolerant to obstruction. The scientific work is called "Improvement of the informational  efficiency of cordless transmitting systems on the base of link channel resource leveling" and it is a study of measure of informational effectiveness during link channel resource exploitation that shows how much its transmission capacity is used. On the base of usage of modern adaptor kit for link channel resourse leveling the boosting of measure of informational effectiveness during link channel resource exploitation was reached to 9...52%.

The young researchers from KPI suggested the way of defining optimal frequency-energetic conditions for link channel resource leveling, the way of defining the tolerant to obstruction extralong block codes of LDPC class characteristics, the way of organization of signal-code sequence for the channel with certain parameters during radiation OFDM mode and the way of adaptive choice of multilevel keying type on the base of reaching maximal cordless communication system efficiency.

The key findings of the research were published in 5 specialized publications, officially approved in 9 international conferences and protected by 4 Ukraine utility model patents. It is of great importance that findings of researches were used in the activity of PAT “ЕЛМІЗ” Enterprise, which took up the license on exploitation of patented findings.
