中文摘要：

在这篇文章，作者为 uplink 多用户考虑线性 precoder 和力量分配的联合设计有有限反馈的多重输出(MIMO ) 通讯系统评估改进位错误的多重输入(BER ) 为所有用户的性能。从电报密码本集合的 Precoder 选择是而不是另外的非最优的标准，直接，基于准确 BER，性能不能在直接基于 BER 标准的力量分配的看法存在完成最佳的 precoder 矩阵，而是靠近形式的表情。从这个观点，作者为 precoder 设计的考虑建议联合传输器优化算法，与为 asymptotic MBER (琥珀) 标准的全部的力量限制。在这个琥珀标准，一个靠近形式的答案与最佳的 precoder 为力量分配被导出。模拟结果证明建议联合设计算法能与一致力量分配和仅仅力量分配的考虑比 precoding 完成好一些的表演。

英文摘要：

In this article, the authors consider joint design of a linear precoder and power allocation for uplink multiuser multiple input multiple output （MIMO） communication systems with limited feedback to improve the bit error rate （BER） performance for all users. Precoder selection from the codebook set is directly based on the exact BER performance, instead of other suboptimal criteria, to achieve the optimal precoder matrix, but closed-form expressions may not exist in the view of power allocation based directly on the BER criterion. From this perspective, the authors propose the joint transmitter optimization algorithm for the consideration of precoder design, with total power constraint for asymptotic MBER （AMBER） criterion. In this AMBER criterion, a closed-form solution has been derived for power allocation with an optimal precoder. The simulation results show that the proposed joint design algorithm can achieve a much better performance than precoding with uniform power allocation and only consideration of power allocation.
