A.V. Shcheglov, Moscow Aviation Institute, associate professor of chair 403, Ph.D.; audelia@inbox.ru

The method of research the immunity noise of communication lines by application of infinitesimal calculus of product integral is described. The equation of a long line with uniform distribution of a line noise on its length is ceived. Transition process for line without loss when noise has an appearance of voltage and current jumps which is evenly distributed on its length is investigated. The decision is put forward for analysis of the line with noises which are randomly distributed along the line. The received results easily are generalized to multiwire lines by representation of elementary piece of the line by multiterminal network that allows investigating line noises not only in lines, but also in ways of passing of signals of various devices and VLSI.

RECURRING COMPENSATION ALGORITHMS TO THE SIGNAL DISTORTION AT ADDITIVE NOISE AND WITH CONSIDERATION OF INTERSYMBOL INTERFERENCE

N.E. Poborchaya, MTUCI, associate professor, Ph.D.; n.poborchaya@mail.ru

Estimation of the random signal parameters due to the further compensation in the presence of Additive White Gaussian Noise and intersymbol interference (ISI) is realized in this paper. Mismatching between the channel and signal is the cause of the ISI occurrence. This mismatching allows increasing the rate of the information transmission. But at the same time the reception quality is decreased due to the ISI. Two estimation procedures comparison is provided: nonlinear filtering method and variational algorithm. Both of them allow dealing with the
ISI.
Keywords: estimation, nonlinear filtering, variational algorithm,modified least square method, intersymbol interference.
