基于子空间的OFDM系统半盲信道估计,是IEEE上的经典文章,请同学们相交流.-Subspace-based blind and semi-blind channel estimation for OFDMsystems(120,2002

In this paper, we investigate blind channel estimation for Multiple Input Multiple Output (MIMO) multi-carrier CDMA (MC-CDMA) systems in the uplink scenario. An Autocorrelation Contribution Matrix (ACM) method is proposed in comparison with the sub
