Abstract
An apparatus includes a first splitter configured to feed a first signal onto a first transmission channel and a second transmission channel, where the first splitter is located in a symmetrical position between the first transmission channel and the second transmission channel, and a vector detection component configured to, when the first splitter feeds the first signal, detect a first signal vector based on a first feedback signal from the first transmission channel, and detect a second signal vector based on a second feedback signal from the second transmission channel.
