description: We analyze the decoding algorithm of text messages, using the knowledge of probabilities of occurrence of letter (character) combinations. Proposed algorithm combines the character encoding of the text derived and modified algorithm of decoding of text symbols, taking into account the probability of occurrence of individual letters and two letter combinations. A comparison of the algorithm correcting characters with the usual algorithm for decoding regular coding and gray coding. The work consists of three sections. In section 1, to implement a simulation model of encoding text, binary phase modulation, demodulation and decoding. In section 2, to obtain the probabilities of occurrence of characters and two-character combinations, made up of Russian letters and a space for artistic text. A rule to encode characters of text using the probability of occurrence of characters and two-character combinations. to implement the algorithm for adjusting symbols using the probability of occurrence of two-character combinations. In section 3 to examine the effectiveness of algorithms of decoding of the symbols at different signal-to-noise in terms of additive normal white noise for the three kinds of text.
