<p>An error correction coding method using a low-density parity-check code includes: dividing an information bit sequence to be processed for error correction coding, into (m-r) pieces of first blocks each comprising a bit sequence having a length n and r pieces of second blocks comprising respective bit sequences having lengths k 1 , k 2 , ..., k r ; a first arithmetic operation for performing polynomial multiplication on the (m-r) pieces of first blocks, and outputting r pieces of bit sequences having a length n; and a second arithmetic operation for performing a polynomial division and a polynomial multiplication on the r pieces of second blocks and r pieces of operation results of the first arithmetic operation, and outputting a bit sequence including redundant bit sequences having respective lengths n-k 1 , n-k 2 , ..., n-k r .</p> |
