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

摘要

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.
