Patent ID: 8559888

Claim:
A signal polarization method, comprising: receiving physical channel signals sent by a base transceiver station; determining a polarization manner of each physical channel signal; and polarizing, by adjusting at least one of an amplitude and a phase of each physical channel signal, the physical channel signals according to the polarization manner; the polarizing, by adjusting at least one of the amplitude and the phase of each physical channel signal, the physical channel signals according to the polarization manner comprises: distinguishing the physical channel signals two channels of signals; and polarizing, by adjusting at least one of amplitudes and phases of the two channels of signals respectively, the physical channel signals according to the polarization manner; the distinguishing the physical channel signals into two channels of signals comprises: distinguishing, based on transmit power of a corresponding physical channel, the physical channel signals into two channels of signals according to the following formula: S + ( t )= A + exp( jφ + ) S ( t ); S − ( t )= A − exp( jφ − ) S ( t ), wherein, S(t) represents a physical channel signal, A + is a first amplitude parameter of S(t), φ + is a first phase parameter of S(t), A − is a second amplitude parameter of S(t), φ − is a second phase parameter of S(t), and transmit power of the physical channel to which S(t) belongs is P=A + 2 +A − 2 .
