Abstract:
1. An encoding method for encoding a codeword to obtain a corresponding parity code, the parity code being embedded in the codeword and dividing the codeword to have intermediate symbol locations between a first and a second set of data symbols, each data symbol forming a coefficient, the first set of data symbols, the second set of data symbols, and the parity code respectively forming a first polynomial (M 1 (x)), a second polynomial (M 2 (x)), and a parity code polynomial (R(x)), the encoding method comprising the following steps: designing a first code generator polynomial (G multiplying the first polynomial (M generating a second code generator polynomial (G generating a third polynomial (M multiplying the third polynomial (M performing an adding procedure to the first remainder polynomial (R obtaining the parity code from each coefficient of the parity code polynomial (R(x)).
