1. A polarization reconfigurable apparatus, comprising:
a signal generation unit;
a signal adjustment unit;
a digital-to-analog conversion unit, and
a transmitter, wherein the signal generation unit, the signal adjustment unit, the digital-to-analog conversion unit and the transmitter are sequentially connected, wherein the transmitter comprises a first port and a second port, and wherein a signal transmitted by the first port is orthogonal to a signal transmitted by the second port;
wherein the signal generation unit is configured to generate a first signal;
wherein the signal adjustment unit is configured to:
determine a polarization mode of a to-be-transmitted signal, wherein the polarization mode comprises one of linear polarization, circular polarization, or elliptical polarization;
divide the first signal into two first signals; and
adjust, based on the determined polarization mode, an amplitude and a phase of a 1st first signal and an amplitude and a phase of a 2nd first signal;
wherein the digital-to-analog conversion unit is configured to perform digital-to-analog conversion on an adjusted 1st first signal to obtain a second signal, and perform digital-to-analog conversion on an adjusted 2nd first signal to obtain a third signal;
wherein the transmitter is configured to transmit the second signal by using the first port, and transmit the third signal by using the second port, wherein the to-be-transmitted signal is obtained by combining the second signal and the third signal; and
wherein a phase difference between the adjusted 1st first signal obtained by the signal adjustment unit and another adjusted 1st first signal obtained by another signal adjustment unit adjacent to the signal adjustment unit is θ, wherein a phase difference between the adjusted 2nd first signal obtained by the signal adjustment unit and another adjusted 2nd first signal obtained by the another signal adjustment unit θ, and wherein θ is determined based on a beam direction of the to-be-transmitted signal.
