ENCODER AND ENCODING METHOD PROVIDING INCREMENTAL REDUNDANCY Russian patent published in 2015 - IPC H03M13/37 

FIELD: radio engineering, communication.

SUBSTANCE: method includes encoding input data words (D) into codewords (Z1, Z2), each comprising a first number K_ldpc of information symbols, an encoding means (1452) for encoding an input data word (D) into a codeword (Z1, Z2, Z3, Z4) such that a codeword comprises a basic codeword portion (B) including a data portion (D) and a basic parity portion (Pb) of a second number N_ldpc-K_ldpc of basic parity symbols, and an auxiliary codeword portion (A) including an auxiliary parity portion (Pa) of a third number M_IR of auxiliary parity symbols, and an encoder output (1454) for outputting said codewords (Z1, Z2).

EFFECT: high probability of error-free reception, reconstructing data with a receiver even in bad reception conditions.
