Blind identification of multidimensional signals and its application in MIMO communication systems

In this paper the MIMO communication system based on redundant spatial encoding, performed by cyclic enumeration of transmission channels, is presented. For this system it is proposed to represent a mathematical model of one-dimensional MIMO channel in the form of a multidimensional SIMO channel. The conditions of blind channel identifiability for this model are formulated. For the blind identification of the multidimensional SIMO channel, the cross-relations method in polynomial interpretation is proposed.
