Abstract

In this paper, we analyze the performance of an adaptive Multiple Input Multiple Output (MIMO) system employing transmit antenna selection and rate adaptation based on channel state information (CSI). Imperfections in CSI due to estimation error and feedback delay are considered. Since CSI is imperfect, the rate of transmission is chosen in order to meet a target outage probability. The average throughput is evaluated for various cases of imperfect CSI using Monte Carlo simulations. Simulation results show that rate adaptation provides significant gains even with imperfect CSI. Furthermore, prediction can be used to effectively combat the effect of feedback delay.
不完全CSIT下MIMO天线选择系统的速率自适应
本文分析了基于信道状态信息(CSI)的发射天线选择和速率自适应多输入多输出(MIMO)系统的性能。考虑了由于估计误差和反馈延迟导致的CSI缺陷。由于CSI是不完美的,因此选择传输速率以满足目标中断概率。利用蒙特卡罗模拟,对各种不完美CSI情况下的平均吞吐量进行了评估。仿真结果表明,即使在不完美的CSI条件下,速率自适应也能获得显著的增益。此外,预测可以有效地对抗反馈延迟的影响。
