FIELD: information technologies.
SUBSTANCE: device and method for block code encoding with low density of parity control (LDPC-code) featuring variable coding rate. The device receives data word and encodes data word into block LDPC-code on the basis of one of two matrices - the first parity control matrix and the second parity control matrix - depending on coding rate to be used in transforming data word into block LDPC-code.
EFFECT: improvement of data transfer reliability.
