【 摘 要 】

For MIMO two-way relay network system,the data flow is asymmetric among users,bystudying the users with antenna distribution relationship between the relay,this paper propose optimization algorithm based on Eigen-matrix and the feasibility of the scheme.At first,this algorithm use rule of Eigen-matrix,it design optimization scheme of interference alignment for each user,at second,based on the distributed iterative algorithm to deduce the optimum matrix of interference suppression.In order to achieve the effect that in the purpose of each client to eliminate interference with other users.Through the simulation results show that the proposed algorithm than the traditional relay forced zero method on the system total rate has increased significantly.
