Performance Analysis of User Cooperative Diversity System Based on Network Coding

In order to solve the problem that non-cooperative communication and the conventional cooperative communication systems only obtain low antenna diversity gain, a user cooperative system model based on network coding is proposed in this paper. The antenna diversity gain with different users by implementing network coding is investigated,the outage probability performance of non-cooperative communication scheme, traditional user cooperative scheme and network coded user cooperative scheme are analysed. Theoretical analysis and experimental simulation show that cooperative scheme with network coding can reduce the system outage probability remarkably and obtain a higher diversity gain. The more cooperative users, the better diversity gain.
