摘要：
In order to reduce the complexity of Block Diagonalization algorithm when the number of users increased and maximize the user capacity supported by the system of MIMO, a new transmission scheme based on Block Diagonalization algorithm and Time Division Multiplexing is proposed in this paper. In the scheme, the users are divided into several groups firstly. Secondly the users of the group should be precoded in Block Diagonalization algorithm. And then the groups are assigned to different slots before transmitting. Simulation results show that, the scheme not only can support more users and low the complexity of Block Diagonalization algorithm but also increase the throughput of the system.
