Prediction of quality of discrete message transmission via ionosperic radiolinks based on channel simulation model

A new approach to predicting the quality of binary message transmission via a narrowband shortwave channel is proposed. This approach is based on using the adaptive simulation model of channel which describes actual mechanisms of short wave propagation in magneto-active spatially non-uniform ionosphere in connection to specific helio-and geophysical conditions. Resultantly, quality of transmission is predicted with accounting for expected structure of the field at a reception site, and time variations of signal level.
