Title:
MULTI-CHANNEL CORRECTION APPARATUS, AMPLITUDE CORRECTION METHOD, PHASE CORRECTION METHOD, TRANSCEIVING SYSTEM AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2018/090207
Kind Code:
A1
Abstract:
Provided are a multi-channel correction apparatus, an amplitude correction method, a phase correction method, a transceiving system and a base station, which relate to the field of antenna communications, so as to reduce the design and implementation complexity of a high-frequency circuit of a correction feed network. In the correction apparatus, a correction feed unit comprises a plurality of conversion units, which act as a detector on a transmitting channel and act as a reference source unit on a receiving channel. The conversion units can implement a direct connection of a channel to a correction control unit, and two adjacent conversion units are jointly coupled to a channel, so that the channel to which the adjacent conversion units are jointly coupled can be used as a basis during correction so as to implement the correction of a plurality of channels, without the need of cascading the conversion units, thereby greatly simplifying the complexity of a correction feed network.
