Abstract

An active array antenna calibration system, a method, an apparatus, and an active array antenna system are provided. The calibration system includes a calibration cable,a power splitting and combininglink and a calibration detection module. The calibration detection module comprises a calibration signal baseband processing chip and a radio frequency transceiver unit connected with the calibration signal baseband processing chip. The calibration cable is respectively connected with the transceiver links of each transceiver radio frequency single board and collects calibration signals of the transceiver links of each transceiver radio frequency single board. The power splitting and combining link is connected with the calibration cable and the calibration detection module, and the calibration signal collected by the calibration cable is sent to the calibration signal baseband processing chip, and the calibration signal baseband processing chip performs calibration processing. Or the original signal is sent to the antenna baseband processing chip of each RF single board, and the antenna baseband processing chip performs calibration processing. The invention realizes the self-calibration function of the multi-channel antenna array through the internal link of the equipment, thereby optimizing the antenna coverage range and the effect.

Description

technical field [0001] The present invention relates to the technical field of mobile communications, and in particular, to an active array antenna calibration system, method, device and active array antenna system. Background technique [0002] At present, in the third-generation mobile communication (3G) network, a communication system architecture composed of a baseband processing unit (BBU) and a remote radio unit (RRU) is used, in which a fiber-optic connection is used between the BBU and the RRU, and one BBU can support multiple RRU. The BBU is connected to the optical interface of the RRU through an optical fiber, the optical interface in the RRU is connected to the digital intermediate frequency, and the digital intermediate frequency is respectively connected to the transceiver array and the transceiver calibration unit. The antenna channel is connected to the passive antenna array, and the transceiver calibration unit is connected to the passive antenna array thro...
