Document Type and Number:
WIPO Patent Application WO/2021/129098
Kind Code:
A1
Abstract:
A base station, and a multi-antenna transceiver and a control method therefor. In the transceiver, an IQ exchange module (10) receives a first correction signal and sends same or receives a second correction signal and sends same to a DSP (50); a digital medium frequency processing module (20) receives the first correction signal and sends same to a downlink service channel, or receives the second correction signal from an uplink service channel and sends same to the IQ exchange module (10); an interface relation module (30) couples the first correction signal from the downlink service channel to an antenna correction link (40) and sends same to the DSP (50), or couples the second correction signal from the antenna correction link (40) to the uplink service channel; the DSP (50) sends the first correction signal and the second correction signal, and calculates a first correction coefficient and a second correction coefficient according to the received first correction signal and second correction signal.
