Network coding realizes the maximum flow in a network by an appropriate coding technique. In this paper, the low density parity check (LDPC) codes are applied to network coding for a multicast network composed of a tree graph. Parts of LDPC codeword are relayed in the network. At each node, received parts of codeword are regarded as punctured codes and restore the data. Numerical results show that a node recovers the data correctly when 63% of codeword is received in a certain network condition. The effects of noise on the block correct rate are also discussed.
