Abstract: This paper introduces an overview of the applications of network coding in wireless relaying networks. Two typical scenarios of wireless network coding are two-way relay networks and multicast retransmission networks. Some key problems of network coding in wireless relaying networks are as follows: (1)Design implementations of wireless network coding; (2)Analyze the capacity of network coding and the corresponding transmission schemes in actual network environments; (3)Investigate how to separate the required signal from the mixed signal for physical layer network coding. Future work on network coding is also summarized.

Key words: network coding, wireless relay networks, throughput
