Abstract

The invention relates to a method and a device for adjusting an intelligent antenna calibrating plate. The device is provided with the intelligent antenna calibrating plate, one or more plastic thin film(s) and a configuration device, wherein the plastic thin film(s) cover(s) the intelligent antenna calibrating plate and is or are used for adjusting a power amplitude value and a phase position value of the intelligent antenna calibrating plate; the configuration device is used for adjusting the intelligent antenna calibrating plate and comprises a net division meter and a quantized adjusting judging device, the quantized adjusting judging device is used for judging a phase position difference value and a power amplitude difference value between antenna ports of the intelligent antenna calibrating plate according to a signal of the net division meter, determining the power amplitude value needing to be adjusted and the phase position value needing to be adjusted according to the judged difference values and the product standard of the intelligent antenna calibrating plate and determining the position and the number of the plastic thin film(s) covering the intelligent antenna calibrating plate according to the values needing to be adjusted, and the quantized adjusting judging device also comprises a visual user interface capable of displaying a schematic diagram of the intelligent antenna calibrating plate and the position and the number of the plastic thin film(s) covering the intelligent antenna calibrating plate. Therefore, the quantized adjusting on the power amplitude value and the phase position value of the intelligent antenna calibrating plate can be realized.

Description

technical field [0001] The present invention generally relates to the field of mobile communication, in particular to a method and device for adjusting a smart antenna array calibration board. Background technique [0002] The concept of smart antenna was proposed in the late 1980s for the needs of mobile communication technology, which can improve the channel reuse rate and base station coverage area of ​​the mobile communication system, and overcome the increasingly serious interference problems such as co-channel and multipath fading. . [0003] When using smart antennas, it is necessary to have the technology to calibrate the smart antenna array. When using a smart antenna in a TDD system, it is based on the reciprocity principle in the electromagnetic field theory, and directly uses the uplink beamforming coefficients to perform downlink beamforming. But for the actual wireless base station, the wireless transceivers of each path cannot be all the same, and its perfor...
