Description: 对于多输入多输出系统, 传统的基于训练序列的信道辨识方法为跟踪信道的变化, 必须
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: A subspace-based blind method is proposed for estimating
the channel responses of a multiuser and multiantenna orthogonal
frequency division multiplexing (OFDM) uplink system.
It gives estimations to all channel responses subject to a scalar matrix
ambiguity and does not need precise channel order information
(only an upper bound for the orders is required). Furthermore,
the scalar ambiguity matrix can be easily resolved by using only
one pilot OFDM block, given that the number of users is smaller
than the number of symbols in the pilot symbol block. Equalization
methods are discussed based on the estimated channels. By using
partial knowledge of the channels, a multipath subspace method is
proposed that reduces the computational complexity. Simulations
show that the methods are effective and robust. Platform: |
