ANTENNA CALIBRATION METHOD AND SYSTEM - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18343119 Titled 'ANTENNA CALIBRATION METHOD AND SYSTEM'
Simplified Explanation
This application describes a method and system for calibrating an antenna. The system consists of a baseband processing unit, a remote radio unit, an antenna array, and a coupled antenna. The antenna array can either send or receive a radio frequency calibration signal from the baseband processing unit. The remote radio unit provides multiple transmission channels, each corresponding to a transmission port. The coupled antenna receives the radio frequency calibration signal from the baseband processing unit and transmits a coupled signal back to the baseband processing unit. The baseband processing unit then calibrates a set of baseband signals based on the difference between the radio frequency calibration signal and the coupled signal.
Original Abstract Submitted
Embodiments of this application disclose an antenna calibration method and system. The system includes a baseband processing unit, a remote radio unit, an antenna array, and a coupled antenna. The antenna array sends a radio frequency calibration signal sent by the baseband processing unit, or receive the radio frequency calibration signal. The remote radio unit provides a plurality of transmission channels, where the plurality of transmission channels correspond to a plurality of transmission ports. The coupled antenna receives the radio frequency calibration signal sent by the baseband processing unit, and transmit a coupled signal corresponding to the radio frequency calibration signal to the baseband processing unit, or send the radio frequency calibration signal. The baseband processing unit calibrates, based on a difference between the radio frequency calibration signal and the coupled signal, a plurality of to-be-sent baseband signals corresponding to the plurality of transmission channels.
