针对基站协作系统的特点，提出一种基于误差修正的有限量化反馈方案. 该方案将信道向量量化过程分为与协作基站数相等的若干步骤，每一步量化均对前一步的量化误差进行修正. 复杂度分析和系统仿真比较表明，与现有的整体反馈方案相比，该方案以稍许牺牲系统性能为代价极大地降低了量化复杂度. 与现有的分别反馈方案相比，该方案在增加少量复杂度的情况下，提高了系统性能. 该方案在复杂度和系统性能方面获得了很好的折中.

 This paper proposes a limited quantization feedback mechanism based on error revising according to the characteristics of base-station coordination system. In this mechanism, the channel quantization process is divided into many steps. The number of the steps equals the number of coordinating base stations. Each quantization step corrects the errors in the previous step. From the complexity analysis and system simulations, it is concluded that the new mechanism reduces quantization complexity with very small degradation in the performance as compared to the existing global feedback mechanisms. It improves the system performance with very little increase in complexity as compared to the existing individual feedback mechanisms. The proposed mechanism provides a good tradeoff between complexity and system performance.
