PROBLEM TO BE SOLVED: To efficiently perform spatial processing for improving characteristics in a multiple input multiple output system. SOLUTION: A first spatial filter matrix for a first transmission span is derived, a first initial spatial filter matrix for a second transmission span is determined on the basis of the first spatial filter matrix, a second spatial filter matrix for the second transmission span is derived on the basis of the first initial spatial filter matrix, thereby deriving spatial filter matrices in a wireless MIMO communication system.
