| 摘 要： | 多用户MIMO系统中，基于SLNR（signal-to-leakage-and-noise，信漏噪比）的预编码方案能够同时考虑噪声和信号泄漏问题，不但提高了系统性能，同时降低了系统的复杂度，但要求基站同时服务的数据流数之和不得大于其发射天线数. 因此，当用户数较多时，需要进行用户调度. 基于SLNR的用户调度准则只需要知道其他用户的信道信息，并能够合理的选择用户，通过仿真得知，该调度准则能够使系统获得良好的性能.

| Abstract: | In multi-user MIMO system based on the SLNR (signal-to-leakage-and-noise) of the pre-coding scheme taking the problems of noise and signal leakage into account, not only improve the system performance but also reduce the complexity of the system. However, the base station is required to service at the same time the number of data streams is not greater than the number of transmit antennas. Therefore, when the number of users is large, the need for the user scheduling. While the user scheduling pre-coding algorithm based on SLNR only need to know the channel information of other users, and reasonable choice of the user, proven, the system can get good performance. |
