FIELD: radio, communication.
SUBSTANCE: base parameter of the second matrix of parity inspection is defined, which meets the rule that has been previously determined in respect to the specified first matrix of parity inspection. Submatrices are generated, which correspond to the part of parity of the second matrix of parity inspection, with usage of the base parameter. Submatrices are generated, which correspond to a part of an information word of the second matrix of parity inspection, with usage of the first matrix of parity inspection and base parameter.
EFFECT: increased efficiency of recovery of corrupt information.
