Abstract: An apparatus for correcting a deviation between a plurality of transmission channels includes a first transmission channel and a second transmission channel. The apparatus also includes a phase offset unit configured to set a phase offset between the first transmission channel and the second transmission channel such that a phase deviation between the first transmission channel and the second transmission channel deviates from zero, a power detection unit configured to detect signal powers of the first transmission channel and the second transmission channel under the phase offset, a processing unit configured to determine, based on the detected signal powers, a deviation correction value between the first transmission channel and the second transmission channel, where the deviation correction value includes a phase correction value, and a phase correction unit configured to set the phase correction value between the first transmission channel and the second transmission channel.

Abstract: The present disclosure relates to 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. One example apparatus includes a receiver and at least one processor. The receiver is 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. The at least one processor is configured to determine a deviation correction value between the first transmission channel and the second transmission channel based on the detected signal vectors.
