  • Calibration method for parallel multi-channel wireless channel measurement and system for the same
    Patent number: 10362551
    Abstract: The present invention discloses a calibration method for parallel multi-channel wireless channel measurement and a calibration system thereof. The transmitting end and the receiving end are disconnected, and are respectively connected to the calibration receiving channel and the calibration transmitting channel, and the calibration receiving channel/calibration transmitting channel cooperates with a measurement channel in air interface measurement, to calibrate a channel response characteristic of the transmitting end and the receiving end. By means of the present invention, a current channel response characteristic between multiple channels can be online supervised in real time, so as to ensure that a measurement error because of an impact of mutual interference between multiple channels can be avoided in the channel measurement process.
