摘要

针对闭环MIMO-OFDM系统，提出了一种新的速率分配算法。新方案利用通道矩阵奇异值的有序统计量，在频域和空间上都比充水的理想方案简单得多。该方案不像“传统的频率平坦约束”方案那样强制使用大型天线阵列，具有较强的灵活性[j]准贤成，2003年1月。在相同的硬件复杂度下，它也优于FFC算法。

Ordered statistics based rate allocation scheme for closed loop MIMO-OFDM system

We propose a new rate allocation algorithm for closed loop MIMO-OFDM system. The new scheme utilizes ordered statistics of channel matrix's singular value and is significantly simpler than ideal scheme which uses water-filling in both frequency and space domain. The proposed scheme is more flexible in that it does not force the use of large antenna array as "conventional frequency flat constraint" scheme does [J.R.B. Joon Hyun Sung, January 2003]. It also outperforms FFC algorithm under equal hardware complexity.
