In 1992 Vadym Slyusar patented the 1st optimal
demodulation method for
N-OFDM signals after
Fast Fourier transform (FFT).[1]
From this patent was started the history of N-OFDM signals theory.[1] In this regard, W. Kozek and A. F. Molisch wrote in 1998 about N-OFDM signals with the sub-carrier spacing , that "it is not possible to recover the information from the received signal, even in the case of an ideal channel."[2] But in 2001 Vadym Slyusar proposed such
Non-orthogonal frequency digital modulation (N-OFDM) as an alternative of
OFDM for communications systems.[3]
The next publication of V. Slysuar about this method has priority in July 2002[4] before the conference paper of I. Darwazeh and M.R.D. Rodrigues (September, 2003)[5] regarding
SEFDM.
The description of the method of optimal processing for N-OFDM signals without
FFT of
ADC samples was transferred to publication by V. Slyusar in October 2003.[6][7]
The theory N-OFDM of V. Slyusar inspired numerous investigations in this area of other scientists.[7]
The Face-splitting product and his properties used for multidimensional smoothing with P-splines[18] and
Generalized linear array model in the statistic in two- and multidimensional approximations of data as well.[19]
Theory of odd-order I/Q demodulators
The theory of odd-order I/Q demodulators, which was proposed by V. Slyusar in 2014,[20][21][22] started from his investigations of the tandem scheme of two-stage
signal processing for the design of an I/Q demodulator and multistage I/Q demodulators concept in 2012.[23]
As result, Slyusar "presents a new class of I/Q demodulators with odd order derived from the even order I/Q demodulator which is characterized by linear phase-frequency relation for wideband signals".[21][24]
Results in the other fields of research
V. Slyusar provided numerous theoretical works realized in several experimental radar stations with
DAAs which were successfully tested.[25][26][27]
1981–1985 – listener of Orenburg Air Defense high military school.[28][29] In this time started the scientific carrier of V. Slyusar, which published a first scientific report in 1985.[30]
June 1992 – defended the
dissertation for a
candidate degree (Techn. Sci.) at the Council of Military Academy of Air Defense of the Land Forces (
Kyiv). The significant stage of the recognition of Vadym Slyusar’s scientific results became the defense of the
dissertation for a
doctoral degree (Techn. Sci.) in 2000.
Professor – since 2005, Honored Scientist and Technician of Ukraine – 2008.
Since 2003 – participates in
Ukraine-
NATO cooperation as head of the national delegations, a person of contact, and national representative within experts groups of NATO Conference of National Armaments Directors[31][32] and technical members of the Research Task Groups (RTG) of
NATO Science and Technology Organisation (STO).
