Abstract:
This article considers the model of impact of non-stationary interference on the satellite communications channels of standard DVB-S and DVB-RCS, and also on the channels with frequency-hopping spread spectrum. The results of the impact of unintentional non-stationary interference on the satellite communications channels, which occurs from stationary and mobile sources of interference with the same average power, were compared. The bit error probability is used as a measure of noise immunity of satellite communications channels. In the article the term time coefficient of the disturbance noise existence was introduced. Its essence is to substantiate the degree of noise energy concentration in some time area of the desired signal. As an indication, characterizing noise immunity of data lines to the influence of unsteady noises the bit-error probability was chosen. It depends on the time coefficient of the disturbance noise existence. In the definite period of time coefficient of the unsteady noise existence for low signal-to-noise ratio they can have a more dangerous effect on data lines with FHSS than the continuous disturbance noise increasing the bit-error possibility.
