Precoding processing method, base station, and communications system |
摘要 |
Embodiments of the present invention provide a precoding processing method, a base station, and a communications system. The precoding processing method includes: implementing beamforming on an antenna array according to information about a direction of arrival of a user equipment to obtain a transformation matrix; transforming a channel matrix according to the transformation matrix to obtain an equivalent channel matrix; and obtaining a precoding matrix required for precoding processing according to the equivalent channel matrix. According to the embodiments of the present invention, after a MIMO system is implemented based on a single antenna array, signals transmitted between the UE and the base station are orthogonal in each beam direction, thereby obtaining a degree-of-freedom gain. |
