Abstract:
Embodiments of the present invention disclose a precoding method and apparatus in a multiple input multiple output system. The method includes receiving a non-constant modulus channel information matrix fed back by a UE; processing the non-constant modulus channel information matrix and removing amplitude information, and obtaining a precoding matrix according to a constant modulus channel information matrix; and precoding data to be sent by using the precoding matrix.
