Abstract
Disclosed is an apparatus for encoding data into linear codes on a ring R, including: as many shift registers as the length of information input thereto, the shift registers having a plurality of memory elements; a shift adding unit for adding values which are cyclically input depending on a check matrix for the linear codes, from the shift registers; a storage unit for storing parity values of the linear codes; and an accumulative adding unit for adding a sum from the shift adding unit and the parity values of the linear codes stored in the storage unit to each other to determine new parity values of the linear codes, and supplying the new parity values to the storage unit.
