TRANSFORMATION DEVICE AND METHOD

摘要

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 R estimation of a long-term wideband transmit spatial correlation matrix with a long-term wideband beamforming matrix u 1 as fed back from a receiver, wherein R estimation = u 1 �¢ u 1 H , 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.
