| 中文摘要 | A non-orthogonal precoding based on oblique projection was developed to mitigate co-channel interference and maximize the sum capacity in a multi-user MIMO downlink system. Moreover block diagonalization precoding and complete orthogonal precoding were studied. The oblique projection scheme can hold the channel gain before power water-filling, but the block diagonalization scheme outperforms the oblique projection scheme and the complete orthogonal scheme after power water-filling. Due to limitations on the number of transmit antennas at the base-station, the precoder is integrated with the user scheduling with various schemes used to improve the effective channel gain. Both the theoretical analysis and simulations indicate that linear precoding has good performance with low complexity and practical application. |
