TOMSK, Dec 4 – RIA Tomsk. Mathematicians of Tomsk State University (TSU) developed methods that 10 times improve the accuracy of evaluating information and allow to restore the image or signal in complex telecommunication systems with high quality, the university’s press service said on Wednesday.

"TSU mathematicians completed a project of the Russian Science Foundation to develop mathematical methods for analyzing signals and images in complex telecommunication and navigation systems that are affected by random noise. The methods they created improve the accuracy of information estimation up to 10 times and make it possible to restore an image or signal with high quality", – is said in the message.

It is noted that the project is focused on the tasks of statistical radiophysics – the problem of data transmission over communication channels. The project executor – are scientists from the TSU International Laboratory of Statistics of Stochastic Processes and Quantitative Finance.

"For example, an airplane flies, transmits a signal. During the transmission of a signal, various noises are superimposed on it and, accordingly, the receiver needs to obtain data that is as close as possible to what was transmitted. Optimal algorithms are built that allow to filter out noise phenomena and get a signal that is as close as possible to the one actually transmitted", – the press service quoted the head of the laboratory Evgeny Pchelintsev.

It is specified that the algorithms created at TSU take into account qualitatively more complex noise in models than previously existed. The results obtained by mathematicians will be used to build new radar systems for operational analysis and monitoring of the environment, satellite navigation systems, promising systems for information receiving and transmitting.

It is added that now scientists of the TSU Faculty of Mechanics and Mathematics have already received two patents for their inventions, a prototype of a device for receiving information using their algorithm was created at Moscow Power Engineering Institute (MPEI). Next year scientists plan to apply their algorithms to the analysis of big data: it can be the data of sociological surveys, physical or financial data.
