A Novel Blind Channel Estimation Algorithm for a MIMO System
In this paper, a novel blind channel estimation algorithm for a Multiple Input Multiple Output (MIMO) system is described. This algorithm is easier to implement than the previously reported blind estimation algorithms because the Channel State Information (CSI) is recovered without performing complex mathematical operations such as Singular Value Decomposition (SVD) or EigenValue Decomposition (EVD). The ambiguity associated with the proposed blind estimation is reduced to the phase ambiguity. The proposed channel estimation algorithm is accompanied by new block coding scheme.
