Information × Registration Number 0220U101761, 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 Прудиус Іван Никифорович, Registration Date 20-02-2020 Organization Lviv Polytechnic National University popup.description2 The main tasks of the problem: 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 periodic structures of CBS; 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; developed and formed the technical requirements and the structure of the information blocks of the command radio frame frame based on the CBS of dimension 19.  Product Description popup.authors Holyaka Roman L.
