Abstract
An antenna calibration method and apparatus, which are used for improving calibration accuracy. In the embodiments of the present invention, sending direction radio frequency channels in an antenna array are grouped into M groups, an intra-group sending calibration pilot frequency sequence of each group of sending direction radio frequency channel is sent at different sending time slots in a time division manner, and along with the decreasing of the quantity of each group of sending direction radio frequency channels, a length of the intra-group sending calibration pilot frequency sequence mapped on each radio frequency channel used for channel estimation is increased, thereby improving the accuracy of an inter-channel compensation factor of each determined sending direction radio frequency channel.
