摘要
Under the conditions of artificial ionosphere disturbances, radio wave propagation in space communication channels is accompanied by the display of effect of scattering (or diffraction) on ionospheric irregularities due to growth of their intensity. An analytical technique is developed for estimating probability of erroneous signal reception in high-speed systems of space (satellite) communication. The probability depends on energetic ration signal/noise and ratio of channel coherence band to signal spectrum width.
