| 摘 要： | 针对目前MIMO-OFDM系统信道估计算法运算复杂度高的问题,本文着重研究低复杂度的基于导频的信道估计算法。首先,发送导频信息获得导频子载波处信道参数,然后利用插值算法来恢复出整个信道的信道参数信息,最后采用运算复杂度低的频域分段最小均方误差(SMMSE)算法,并与基于训练序列的LS和MMSE这两种基本的信道估计算法进行了比较。

| Abstract: | Abstract ：Aiming at the problem of high computation complexity of MIMO-OFDM system estimation algorithm, this paper researches a pilot-based channel estimation algorithm with lower complexity. Firstly, by sending pilot information, we acquire the pilot subcarrier channel parameters, and then by using interpolation algorithm we recover channel parameter information of the whole channel. Finally we adopt the channel estimation algorithm of minimum mean square error （SMMSE） with lower complexity and compare with two basic channel estimation algorithms of LS and MMSE which based on training sequence. |
