A New Scheme to Generate Multiple Weights in the Opportunistic Beamforming Systems

摘要：

A new scheme to generate multiple weights used in opportunistic beamforming (OBF) is proposed to deal with the performance degradation due to the fewer users in the OBF systems.In the proposed scheme,only two mini-slots are employed to create effective channels,while more channel candidates can be obtained via linearly combining the two effective channels,thus increasing the multiuser diversity and the system throughputs.The simulation results verify the effectiveness of the proposed scheme.
