Abstract. Binary error correcting encoding by means of the two-base numeration system with radices 2 and 3 is proposed. The properties and error correcting capabilities of these codes for one and two errors are analyzed. A special kind of (2,3)-code, lower (2,3)-code, is introduced to provide the error-correcting properties. Tabl.: 3. Refs: 5 titles.

Keywords: error-correction encoding, prefix code, error correction.
