FIELD: physics, communications.
SUBSTANCE: invention concerns communication technology and claims methods of obtaining eigen vectors on the basis of guiding reference signal, used in spatial processing. Guiding reference signal is a pilot signal transmission over one eigen mode of MIMO channel in symbol period, using guiding vector for this eigen mode. Guiding reference signal is used in singular value evaluation and matrix and in left-hand eigen vector matrix of channel response matrix. Matrix with squared columns can be obtained via QR-expansion, minimum square error calculation or polar decomposition. Matrix evaluations can be used in coordinated filtering of data transfer received over first communication line, and in spatial processing of data transfer over second communication line (for reverse first and second communication lines).
EFFECT: obtaining eigen vectors on basis of guiding reference signal.
