无线衰落信道下MIMO-OFDM系统信道估计的研究
摘要
本文的工作是围绕无线衰落信道条件下MIMO-OFDM系统的信道估计方法展开的。
第一章阐述了无线衰落信道的各种相关概念，同时给出了无线衰落信道的几种统计模型和计算机仿真算法。
第二章论述了MIMO和OFDM的基本原理。
第三章介绍了一种基于导引符号的MIMO-OFDM系统的信道估计方法及其改进型方法，同时提出了一种适合于极端衰落信道条件下的基于导引符号的信道估计方法。
第四章介绍了一种基于子空间的盲信道估计方法。这种方法适用于采用冗余线性预编码的MIMO-OFDM系统。
This thesis focuses on the channel estimation for MIMO-OFDM systems in wireless fading channels.
In chapter 1 ,the characterization and some statistic models and simulation models of the wireless fading channels are been introduced.
Chapter 2 is paid on the theories of MIMO and OFDM.
In chapter 3,a based on pilot symbols channel estimation method and its simplifiede method are discussed in detailed. In this chapter we bring forth a method that is fit to the extremely fading channels.
In chapter 4,a based on subspace blind channel estimation method is introduced. This method is suitable to the MIMO-OFDM systems which adopt linear percodeing.
