Network Coding in the Next-generation Mobile Communication Network

In this paper,the basic principle of network coding is introduced,the construction ways and their advantages and disadvantages of network coding are compared,and then the joint encoding and decoding schemes based on network coding and physical network coding in the Gaussian channel and multiple access channel are described.Finally,the network coding scheme based on the technologies of MIMO and cooperative diversity is reviewed through analysing the relative merits of the joint coding schemes,and the future research direction is discussed according to the new problems in LTE-A.
