| Abstract: |
| In this paper,the basic principle of network coding is introduced,
the construction ways and their advantages and disadvantages of ne
twork coding are compared, and then the joint encoding and decoding sch
emes based on netwo
rk coding and physical network coding in the Gaussian channel and multiple acces
s channel are described.Finally,the network coding scheme based on the technol
ogies of MIMO and cooperative diversity is reviewed through analysing the relati
ve merits of
the joint coding schemes, and the future research direction is discussed accord
ing to the new problems in LTE-A. |
| Key words: wireless communication network network coding joint coding cooperative diversity |
