Claim Text:
1. An encoding method comprising generating an encoded sequence comprising: n−1 information sequences denoted as X the predetermined parity check matrix is a first parity check matrix or a second parity check matrix, the first parity check matrix corresponding to a low-density parity check (LDPC) convolutional code using a plurality of parity check polynomials, the second parity check matrix generated by performing at least one of row permutation and column permutation with respect to the first parity check matrix, and given e denoting an integer no less than zero and no greater than m×z−1, α denoting an integer no less than one and no greater than m×z, and i being a variable denoting an integer that is no less than zero and no greater than m−1 and satisfies i=e%m where % denotes a modulo operator, where b where, in Math. 1 and Math. 2, p denotes an integer no less than one and no greater than n−1, q denotes an integer no less than one and no greater than r D denotes a delay operator, X a when x and y are integers no less than one and no greater than r when s=p, and v α=1.
