Claim 12:
13. A method for correcting a deviation between a plurality of transmission channels and implemented by an apparatus, the method comprising:
feeding, by a first splitter of the apparatus, a first signal onto a first antenna corresponding to a first transmission channel of the transmission channels and onto a second antenna corresponding to a second transmission channel of the transmission channels, wherein the first splitter is located at a symmetrical position between the first antenna and the second antenna; and
detecting, by a vector detector coupled to the first splitter and when the first splitter feeds the first signal, a first signal vector based on a first feedback signal from the first transmission channel and a second signal vector based on a second feedback signal from the second transmission channel, wherein the first signal vector and the second signal vector are for determining a first deviation correction value between the first transmission channel and the second transmission channel, and wherein the first deviation correction value is for correcting a deviation between the first transmission channel and the second transmission channel;
feeding, by a first correction coupling channel of the transmission channels, the first signal onto a third transmission channel through a third endpoint of the first correction coupling channel;
feeding, by a second correction coupling channel of the transmission channels, the first signal onto a fourth transmission channel through a fourth endpoint of the second correction coupling channel;
detecting, by the vector detector, a third signal vector based on a third feedback signal from the third transmission channel when the first signal is fed onto the third transmission channel; and
detecting, by the vector detector, a fourth signal vector based on a fourth feedback signal from the fourth transmission channel when the first signal is fed onto the fourth transmission channel,
wherein the third signal vector and the fourth signal vector are for determining a second deviation correction value between the third transmission channel and the fourth transmission channel, and
wherein the second deviation correction value is for correcting a deviation between the third transmission channel and the fourth transmission channel.
