Abstract
The present invention provides a transformation apparatus for transforming a long-term wideband channel property feedback. The transformation apparatus comprises: a first transformation unit for constructing an estimation Rof a long-term wideband transmit spatial correlation matrix with a long-term wideband beamforming matrix uas fed back from a receiver, wherein R=uu, wherein H indicates the conjugate transposition of a matrix; and/or a second transformation unit for directly obtaining a long-term wideband beamforming matrix or a precoding matrix by using a long-term wideband transmit spatial correlation matrix as fed back from a receiver. According to the technical solution of the present invention, a corresponding transformation method and apparatus is also provided.
