US 11,456,807 B2 · Apparatus and method for correcting deviation between plurality of transmission channels

Abstract

This application provides an apparatus for correcting a deviation between a plurality of transmission channels, which includes a first transmission channel and a second transmission channel. The first transmission channel and the second transmission channel are respectively connected to a first endpoint and a second endpoint of a correction coupling channel. The apparatus includes a vector detection unit, configured to: when a first signal is fed at the first endpoint and a second signal is fed at the second endpoint, respectively detect a plurality of signal vectors based on a plurality of feedback signals of the first transmission channel and the second transmission channel; and a processing unit, configured to determine a deviation correction value between the first transmission channel and the second transmission channel based on the detected signal vectors.

Dependent claims

A communications system, comprising:

a plurality of channels comprising a first transmission channel, a second transmission channel, and a third transmission channel, wherein the plurality of channels are configured to work in a receiving state;
a reference signal generator, wherein the reference signal generator is configured to produce a first reference signal and a second reference signal;
a coupling channel coupled to the plurality of channels, wherein the first reference signal is fed to the plurality of channels through the coupling channel, wherein a feedback signal is outputted from the plurality of channels based on the first reference signal;
and
a mixer, wherein the mixer is configured to perform frequency mixing on the feedback signal and the second reference signal.
