LTE-A系统中CSI-RS导频信道估计误差建模

he Channel Estimation Error Modeling by Using CSI-RS Pilot Signal in LTE-A system

中文摘要英文摘要

为了满足4G技术标准要求,LTE-Advanced在LTE系统的基础上继续演进,尤其是在空域的MIMO技术方面。它将下行链路发送天线扩容为8个,传输层数扩容为8层。相应的,为匹配天线数的增加,使用CSI-RS导频替换LTE原有的CRS导频。由于新旧导频的差异性,原有的信道估计方法可能不适用。本文选取了几种常用的信道估计算法,统计这些算法在利用CSI-RS导频进行信道估计时的估计误差。

In order to meet the 4G standards,LTE-Advanced continued evolution on the basis of LTE system, especially in the MIMO technology. LTE-A can support eight transmit antennas and eight transport layer. To match the transmit antennas and transport layer, LTE-A alternative CRS pilot with CSI-RS pilot. Some old channel estimation algorithm may not be able to use. In this paper, we choose some algorithms which is often used to simulate, in order to count the estimate error of these alogrithms.
