<p>The present invention relates to a calibration apparatus for a receiving link of array communication system, comprising an uplink calibration signal generation device, an uplink calibration signal allocation device, a clock generation device and n couplers, an array receiver having a calibration function and a feeder device; the uplink calibration signal generation device is used to generate uplink calibration signal according to a clock signal output by the clock generation device; the uplink calibration signal allocation device is used to divide the uplink calibration signal into n uplink calibration signals; the n couplers are used to couple the uplink calibration signal and receiving signal; the array receiver having a calibration function is used to calculate a weigh value of the array receiving link and to calibrate this value. The present invention needn't a specific calibration signal transmission apparatus, and the structure of the calibration signal generation device in the present invention is simple; and when the generated uplink calibration signal calibrates an array, it has smaller influence on normal communication of other users, and may calibrate an inconsistent error of frequency response of each receiving link within this array on-line.</p> |
