| Abstract: |
| The current existed scheduling schemes which are generally derived from the antenna selection algorithms can improve the sum rate of MU MIMO system to some extent. However, these schemes can not make the best of multi user diversity gain, thus incurring capacity loss. To overcome these disadvantages, in this paper, a novel user scheduling scheme based on the lower bound capacity of MU MIMO broadcast channel is proposed for the multi user zero forcing precoding system. In the proposed scheme, the base station will schedule those users that can achieve the maximal lower bound capacity of MU MIMO system by certain optimal criterion. Simulation results are exhibited to indicate that the proposed scheme can provide performance improvement than other existed scheduling schemes. |
