With the spread of mobile devices, image and video transmission is in great demand. The use of multiuser multiple-input multiple-output (MU-MIMO) systems, where multiple data can be sent to multiple users, is highly expected. This paper proposes a novel power allocation scheme for MU-MIMO systems, which minimizes the variance of channel capacities of each spatial stream of all users to achieve user fairness in terms of video quality. In addition to the user fairness, we make the spatial streams which convey visually more important information be high-quality for achieving high video quality. Simulation results show that the proposed power allocation enables to equalize video quality even if the distances between a transmitter and users are different. |
