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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for calibration of an antenna","description":"An antenna calibration method and apparatus are used for improving calibration accuracy.
