Abstract:
1. An encoding method comprising the steps of: supplying three different types of parity check polynomials for creating a Low-Density Parity-Check Convolutional Code of a coding rate of (n−1)/n (where n is an integer of 2 or more), the Low-Density Parity-Check Convolutional Code created by using a parity check matrix in which three check equations are arranged repeatedly, and switching the three different types of parity check polynomials by a period of 3 periodically and generating a low-density parity-check convolutional codeword using input data and the switched parity check polynomial of the three different types of parity check polynomials, wherein, the three different types of parity check polynomials are respectively represented by the following three Equations; said b said n in the three Equations is the integer n used in the coding rate.
