Information × Registration Number 0221U102590, 0119U002259 , R & D reports Title Research and development of methods, algorithms and means of synthesis of signal-code structures of noise-preventing secretive radio data transmission systems popup.stage_title Head Prudyus Ivan N, Registration Date 06-02-2021 Organization Lviv Polytechnic National University popup.description2 The main tasks of the problem in the completed work: the method for the synthesis of optimal periodic structures of the CBS is developed, which eliminates the restrictions on their dimension; developed using the apparatus of theory, a refined method and algorithm for the synthesis of optimal CBS with optimal periodic and aperiodic ACF; The basis for the synthesis method of quasi-orthogonal sets of code modulating sequences for security code constructions using the basic structures of code binary sequences and selected subsets (with the property of cyclic orthogonality), Walsh functions was developed and presented, analytical expressions for estimating the parameters of ACF and CCF signal-code constructions of these sets; issues of the use of sets of quasi-orthogonal SCCs in multi-position radar systems have been worked out to improve the accuracy of estimates of the coordinates of objects with the simultaneous disclosure of the ambiguity of measurements designed, manufactured and investigated noise-proof components for use in multi-channel noise immunity of electronic systems (RES).  Product Description popup.authors Bachyk Dariia R Holyaka Roman L Hryvachevskyi Andrii P Dmytruk Veronika A Dub Petro B Kuzyk Andrii O Miskiv Volodymyr-Myron V Naida Nazar - Vasyl I Oborzhytsky Valerii I Storozh Volodymyr H Fabirovskyy Serhiy Ye Faychuk Valentyn O Shapovalov Yurii I Yankevych Roman V popup.nrat_date 2021-02-06 Close
