Abstract

The article considers the process of data transmission over an information channel with frequency modulation, in which the carrier signal is a pulse stream with a Poisson distribution of events. The information parameter of such a signal is the instantaneous flux density. In practice, in the existing typical signal processing structure, the instantaneous density estimate is replaced by the flux intensity estimate, which results in an error from the statistical smoothing of nonlinearity in the process of signal conversion on the receiving side to conflicting requirements for the choice of system parameters during its optimization. The situation is analyzed in dynamic modes, when the signals transmitted over such a stochastic channel change in time and the information flow becomes non-stationary. The data processing operation is considered due to the non-linearity of the channel and the limited sampling period. The paper proposes calculation formulas for the analysis of the methodological error caused by the statistical smoothing of the channel nonlinearity. The free-distribution Scilab software package was used to verify and confirm the results of theoretical studies
