FIELD: digital audio-radio-broadcasting.
SUBSTANCE: invention concerns methods and devices for encoding digital information, containing encoding stages with direct correction of errors in a set of bits of digital information with usage of complementary ultra-precise codes with displayed configuration; modulation of a set of carrying signals with bits, corrected by direct error correction; and transmission of carrying modulated signals. Modulation may contain a stage of independent amplitude manipulation of cophased and quadrature components of QAM-set with usage of Gray codes corresponding to amplitude levels. Also, receives for such signals are disclosed.
EFFECT: increased reliability of transmitted digital information through communication channel under certain fadeout or interference conditions.
