Abstract

We propose a new rate allocation algorithm for closed loop MIMO-OFDM system. The new scheme utilizes ordered statistics of channel matrixýs singular value and is significantly simpler than ideal scheme which useswater-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 [3]. It also outperforms FFC algorithm under equal hardware complexity.
