简介：在这份报纸，线性基于漏的precoders的设计被考虑为多重输入多重产量(MIMO)downlinks。我们的建议计划最小化总数在每个用户的signal-to-leakage-plus-noise比率(SLNR)下面播送力量限制。当基础车站知道完美的隧道状态信息(CSI)时，设计问题的合适的重新阐述允许semidefinite的成功的申请松驰(SDR)技术。当基础车站与有限评价错误知道有瑕疵的CSI时，设计问题能用semidefinite节目(SDP)被解决。同时，它能动态地根据每个用户的隧道状态分配每个用户的SLNR阀值，因此它比另外的类似的基于SINR的precoding方法更可行。用大SLNR阀值，建议设计更好举办的模拟结果表演在高signal-to-noise比率(SNR)比maximal-SLNRprecoding方法咬了错误率(BER)性能。而且当基础车站知道有瑕疵的隧道状态信息时，建议precoder对隧道评价错误柔韧，并且比另外的类似的基于SINR的precoding方法有更好的BERpreformance。
