Синтез алгоритмов нелинейной обработки информационных параметров сигнала при воздействии узкополосных помех с негауссовским характером распределения

Abstract

Reviewed and analyzed issues related to the synthesis of algorithms for estimation of parameters of the signal under the influence of narrowband interference with naguszewski the nature of the distribution. It is shown that the existing interference filtering algorithms are effective only when the detunings between the measured parameters and their estimates are so small that they allow the representation of the posterior probability density distribution of the information signal parameters in a series in powers of the indicated detunings not higher than the second. Structural schemes that realize nonlinear processing of information signals in a servo system are proposed, when detunings can reach quite large values.
