Claim:
1. An encoding method comprising: generating, by performing encoding of coding rate 2/4 on an information sequence X wherein the predetermined parity check matrix is one of a first parity check matrix and a second parity check matrix, the first parity check matrix corresponding to a low density parity check (LDPC) convolutional code that uses a plurality of parity check polynomials, the second parity check matrix being generated by performing at least one of row permutation and column permutation on the first parity check matrix, wherein two parity check polynomials satisfying zero are provided for each of 1×P wherein each parity check polynomial satisfying zero of the LDPC convolutional code is expressed by one of a first group of expressions or one of a second group of expressions, wherein the first group of expressions consist of the following expressions: where wherein the second group of expressions consist of the following expressions: where
