摘要

本文分析了不同信道估计器在不同天线相关条件下的性能。本分析是针对3GPP长期演进(LTE) Release 8 (R8)中考虑的各种空间复用技术进行的，使用了大量的模拟。通过考虑LTE下行链路系统参数和LTE信道模型，对信道估计器的性能进行了测试。最后给出了信道估计对LTE系统预编码性能的影响。

Performance of MIMO channel estimation in LTE downlink

In this paper we analyze the performance of different channel estimators under different antenna correlation conditions. This analysis is performed for various spatial multiplexing techniques considered in 3GPP Long term evolution (LTE) Release 8 (R8) using extensive simulations. By considering the LTE downlink system parameters and the LTE channel model, we measure the performance of channel estimators. Finally we present the performance of channel estimation on the performance of precoding in LTE systems.
