Abstract
A wireless batch calibration apparatus, a wireless batch calibration system and a wireless batch calibration method. The wireless batch calibration apparatus includes a wireless transceiver, a processor circuit and a storage circuit. The wireless batch calibration apparatus receives a reference signal from a golden sample and a to-be-calibrated signal from each of a plurality of to-be-calibrated devices. The wireless batch calibration apparatus calculates the compensation value of each to-be-calibrated device, generating a compensation polynomial according to the compensation value and a calibration precision of each to-be-calibrated device, and establishes a calibration table. The wireless batch calibration apparatus writes the compensation polynomial and a setting bit back to each to-be-calibrated device, and completes the batch calibration of a plurality of to-be-calibrated devices.
