Abstract
The present invention relates to an apparatus and a method capable of achieving closed loop MIMO communications, using reduced feedback, without a loss in system performance. In one embodiment of the present invention, a phase-rotated right handed singular vector matrix is derived from an estimation result of a MIMO channel (stepsand). Then, a coefficient are fed back (step). The coefficient is associated with an element in the phase-rotated right-handed singular vector matrix.
