Real-time prediction of quality of binary message transmission via radiolinks using a 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 simulation adaptive model of a 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, the quality of transmission is predicted with the use of expected structure of the field at a reception site, and time variations of signal level.
