Abstract
A description of the algorithm for optimal symbol-by-symbol reception of signal structures based on correction coding in non-binary Galois fields is given. The results of modeling this algorithm are given in order to study its noise-immunity for transionospheric channels with fading due to scattering on ionospheric irregularities for a number of digital signals with multi-level phase shift keying in combination with a correction code with a parity check in Galois fields. It is shown that for these channels the use of a symbol-by-symbol reception algorithm provides an energy gain of up to 4.5...24 dB in relation to the reception of signals without coding.
