Gadzhyiev M. Synthesis of optimal algorithms for signal detection under the joint influence of obstructing factors

Object is the processes detection and distinction of signals under any influence of hindrances, and also their integrated influence. The purpose is the synthesis of optimum algorithms of reception of elements of code designs and code words for the analog and discrete systems of the transfer based on the reception standards of distorted elementary signals or distorted code designs under the influence of certain types of hindrances or combined influence of various stirring factors. Research methods are the methods of the theory of statistical decisions; variations calculus of the linear equations; mathematical apparatus, that is characterized for the correlation functions analysis; methods of mathematical statistics and probability theory; modeling methods on the PC; methods of redundancy coding. Theoretical and practical results include: 1. Using of the generalized algorithm of signals detec-tion in the information processing radio engineering system allows to descries power characteristics of information signals with-out change of capacity of the channel. 2. Designed the quality assessment algorithms for the timer signals constructions are based on the places of crossing of zero level within the code word. 3. It was experimentally received by using of the statistical parame-ters of Gilbert model channels. 4. It was proposed the quality transformation Algorithms of transfer on "good" intervals in Gilbert model channel in transfer speed with the subsequent transformation of a gain of speed in quality of transfer on all interval of the communication line are offered. 5. Recommendations about methods of suppression of the concentrated hindrances by means of weight functions are formulated. 6. It was proposed the increase of data transfer speed algorithms in systems with feedback not less than two time in comparison with systems based on binary redundancy codes. 7. The synthesized generalized detection of signals algorithm doesn't demand development of new element base, so that is valuable for practical realization. Scientific results include: 1. on the basis of the relation of credibility for the first time it is developed the generalized method of detection of signals on the basis of two statistical selections - selections of area of time-and-frequency space of hindrances where emergence of a sig-nal and selection of supervision of the same space area in which the signal precisely absent is possible. 2. It was got further devel-opment the theory of correlation reception based on one selection of supervision at detector realization for simple binary detec-tion. 3. It was for the first time theoretically proved detection improvement of quality method due to introduction of additional time-and-frequency space of hindrances. 4. It was for the first time solved the problem of dispersions definition of two correlated random variables. 5. It was for the first time received analytical expressions for an assessment of quality detection indicators due to introduction of additional space. 6. It was for the first time realized the telemetric messages transfer operator in system of a class of an exception on mod A. 7. It was for the first time offered the data transfer method of simplex system based on an analysis exception of the accepted signals in a "bad" condition of the channel. 8. It was theoretically proved possibility data transfer speed increase method for adaptive systems with feedback based on flow mistakes increasing founded in a "good" state. 9. It was devel-oped the theory of correcting TSK synthesis and improved the using as coefficient coprimes numbers. Results of work are intro-duced in such organizations, as: The Odessa national academy of communication of A.S. Popov, the Azerbaijani technical univer-sity (Baku), Research sector of Institute of Space Researches of Natural Resources (Baku, republic Azerbaijan), VAT "Ukrtele-com", VAT "Zapor_zhzhyaoblenergo", "Aztelekom" (.Baku ), The results are offered for use in the organizations and research es-tablishments for developmant the modern equipment of telecommunication, and also in educational process of higher educational institutions and for research work of teachers, graduate students, doctoral candidates.
