| Abstract(in English) | Several user selection schemes have been proposed for multiuser MIMO downlink systems. However, these user selection schemes do not take security into consideration. One possible scenario is that a transmitter sending messages to multiple receivers in the priori presence of an eavesdropper. In this report, we propose a user selection scheme with secrecy capacity for multiuser MIMO downlink system. The security level relative to each user is measured by the secrecy capacity of its corresponding downlink channel. In the proposed scheme, the transmitter selects a user set so that their secrecy capacities are larger than zero. Thus, the transmitter can send messages to users securely. The proposed scheme can be applied to conventional scheduling schemes, such as maximum capacity scheduling and proportional fairness scheduling. Simulation results show that the proposed scheme provides secure transmissions and has little degradation of performance of system capacity and fairness when applied to conventional scheduling schemes. Hence, we show that the proposed scheme is an effective user selection scheme to guarantee secrecy of communication. |
