Abstract
An encoding method for encoding information bits into a codeword by a linear code is provided. The information bits appear in the codeword as a part of the codeword. The linear code is a code in which a codeword resulting from cyclically shifting an arbitrary codeword by p bit positions is also a codeword. A code polynomial having the codeword in which the information bits appear as a part thereof is computed by executing an arithmetic operation of p polynomials G(x), . . . , G(x) and a polynomial having the information bits as coefficients. Accordingly, a quasi-cyclic (QC) code can be encoded by only polynomial operations, and an encoder can be simplified.
