| Abstract(in English) | It is well known that LDPC codes can exhibit excellent performance by iterative decoding with O(n) computational complexity. As for their encoding, however, no algorithm has been developed that can be executed with computation less than O(n^2). Therefore, it has been one of the most important research subject to reduce computational complexity of encoding of LDPC codes. In this paper, we will survey the conventional approaches to reduce computational complexity of encoding of LDPC codes. Then the encoding method of LDPC codes that can be executed with O(n) computation will be introduced. |
