Research Abstract |
Network coding is studied for efficient communication in networks. For reliable communication, error correcting code is used to encode data of network coding. This study aims to derive decoding method of codes and its performance analysis. Several decoding methods are given. It is shown that joint weight distribution of codes is very important for performance analysis. MacWilliams identy for joint weight distribution is derived for general network structure.
