针对多用户 MIMO 系统,分析了信道估计误差与量化误差对系统性能的影响.首先推导出损失速率的上界,然后利用该上界,设计了一种有限反馈方案,该方案有效地解决了干扰受限问题,最后用仿真结果验证了该上界的正确性与反馈方案的有效性.

@@@@This paper analyzes the effects of channel estimation error and quantization error on the performance of the multiuser MIMO system.The upper bound to the rate loss is derived, and then we design a limited feedback scheme to avoid the interference-limited by using the upper bound.Numerical results are provided to verify the designed scheme and the upper bound to the rate loss.
