发送大量冗余信息, 传输效率较低 而基于子空间的纯盲方法又带有不可避免的模糊性, 辨识结果
精度不够。在子空间法的基础上, 利用少量训练符号估计出模糊矩阵, 以此矫正子空间法得到的结
果。仿真结果显示: 在保证辨识精度的前提下, 该方法减少了训练符号等冗余, 提高了传输效率。-In o rder to t rack the channel variat ion of MIMO OFDM sy stems, t radit io nal channel

Description: The problem of channel equalization via channel
identification (CEQCID) that has previously been considered by a
handful of researchers is explored further. An efficient algorithm
for mapping the channel parameters to the equalizers coeficients
is proposed. The proposed scheme is compared with a lattice
least squares (LS) based receivers. For the particular application
of the high frequency (HF) radio channels, we find that the
CEQCID has lower computational complexity. In terms of the
tracking performance, also, the CEQCID has been found to be
superior to the LS based receivers [4]. We emphasize on the
implementation of a fractionally tap-spaced decision feedback
equalizer (DFE) and compare that with the T-spaced DFE of
[4]. We show that the former is a better choice for the multipath
