Method and apparatus for shortening and puncturing of non binary codes

The present invention relates to an efficient shortening and puncturing methods and apparatus of the non-binary LDPC code, the process of the transmitting end for shortening and puncturing the non-binary code is at least one based on the modulation scheme from the information symbols that make up the non-binary code, at least a process to reduce the information bits and the information bit is reduced with at least one of the information process, and at least one parity code based on the modulation scheme in the at least one parity symbol obtained through the encoding to encode the symbol including the step of boring a, it may support a variety of modulation schemes with a single non-binary codes.
