Abstract

In the cellular MIMO systems, the system capacity can be increased by multi-user diversity (MUD). On the other hand, the system capacity can also be increased by effective frequency reuse factor allocation (FRF) algorithm. In this paper, a multi-user hybrid FRF algorithm is proposed. Both MUD and effective FRF allocation will be realized. As a result, the system capacity is increased greatly. The system capacities by using the proposed algorithm are theoretically analyzed and the effectiveness of the multi-user hybrid FRF algorithm is testified by numerical results.
