Fig. 7 is the isoboles after synthesizing further for the signal of the first logic port and the second logic port in the signaling method embodiment 1 of multiple antennas of the application.As shown in Figure 7, the equivalent signal of final synthesis is the P of 2 times ₀₁with the P of 2 times ₁₂.As can be seen from above-mentioned derivation and Fig. 7, in the equivalent signal after synthesis, the equivalent signal P of the first logic port ₀₁with the equivalent signal P of the second logic port ₁₂, mutually orthogonal.When therefore can reduce subscriber equipment Received signal strength, the mutual interference that the signal of the first logic port and the signal of the second logic port produce.

In sum, in the present embodiment, by corresponding to the weighting weights of the first logical signal according to the antenna in first group of antenna, determine the weights of other 12 antennas that the signal of the first logic port is corresponding, determine the weights of 16 antennas that the signal of the second logic port is corresponding; For the signal of described first logic port, be that the weighting weights of m group antenna add negative sign; For the signal of described second logic port, be that the weighting weights of n-th group of antenna add negative sign; Wherein, the absolute value of the difference of m and n is 2; The equivalent signal of the equivalent signal of the first logic port and the second logic port can be made mutually orthogonal, and then the mutual interference that the signal reducing the Different Logic port that multiple antenna sends simultaneously produces when being received by subscriber equipment.

The method of prior art can be adopted to determine the weighting weight w that the signal of the first logic port is corresponding ₁.

Step 802: the weighting weights determining each antenna in first group of antenna and the 3rd group of antenna are w ₁;

The weighting weight matrix that can obtain the signal of the first logic port is,

W ₁＝[w ₁w ₁00w ₁w ₁00w ₁w ₁00w ₁w ₁00]。

Wherein, because the first logic port does not use described second group of antenna and the 4th group of antenna to send signal, therefore the weighting weights of described second group of antenna and the 4th group of antenna correspondence position are 0.

Step 803: obtain the weighting weight w that the signal of the second logic port is corresponding ₂;

The method of prior art can be adopted to determine the weighting weight w that the signal of the second logic port is corresponding ₂.

Step 804: the weighting weights determining each antenna in second group of antenna and the 4th group of antenna are w ₂;

The weighting weight matrix that can obtain the signal of the second logic port is,

W ₂＝[00w ₂w ₂00w ₂w ₂00w ₂w ₂00w ₂w ₂]。

Matrix W ₂in 16 weighting weights corresponding with the first to the 16 antenna respectively from left to right.

Wherein, because the second logic port does not use described first group of antenna and the 3rd group of antenna to send signal, therefore the weighting weights of described first group of antenna and the 3rd group of antenna correspondence position are 0.

Step 805: the phase symbol changing the weighting weights of some antennas in described first group of antenna is described first polarised direction with the direction of the signal making described first group of antenna synthesis;

In the present embodiment, the direction of upper right can be pointed to as the first polarised direction using in the dual polarized antenna in Fig. 1 by lower-left, using in the dual polarized antenna in Fig. 1 by the direction of sensing upper left, bottom right as the second polarised direction.

Before Fig. 9 is the phase symbol change of the application for the weighting weights of antenna in the signaling method embodiment 2 of multiple antennas, the corresponding relation schematic diagram of the signal of the first logic port and the weights of antenna.

In order to the direction of the signal making described first group of antenna synthesis is described first polarised direction, multiple phase symbol can be had to shift gears.Such as, the phase symbol of the signal of antenna 9 can be changed, make the signal of antenna 9 contrary with the sense of antenna 10, or, the phase symbol of the signal of antenna 10 can be changed, make the signal of antenna 10 contrary with the sense of antenna 9.

Suppose the phase symbol of the signal changing antenna 10, then the weighting weight matrix of the signal of the first logic port becomes,

W ₁＝[w ₁w ₁00w ₁w ₁00w ₁-w ₁00w ₁w ₁00]

Step 806: the phase symbol changing the weighting weights of some antennas in described 3rd group of antenna is described second polarised direction with the direction of the signal making described 3rd group of antenna synthesis;

Identical with step 805 principle, suppose the phase symbol of the signal changing antenna 5, then the weighting weight matrix of the signal of the first logic port becomes further,

W ₁＝[w ₁w ₁00-w ₁w ₁00w ₁-w ₁00w ₁w ₁00]

Step 807: the phase symbol changing the weighting weights of some antennas in described second group of antenna is described first polarised direction with the direction of the signal making described second group of antenna synthesis;

What send in second group of antenna and the 4th group of antenna is the signal of the second logic port.

Before Figure 10 is the phase symbol change of the application for the weighting weights of antenna in the signaling method embodiment 2 of multiple antennas, the corresponding relation schematic diagram of the signal of the second logic port and the weights of antenna.

Identical with step 805 principle, the phase symbol changing antenna 11 or antenna 12 all can make the direction of the signal of described second group of antenna synthesis be described first polarised direction.

Suppose, change the phase symbol of antenna 11, then the weighting weight matrix of the signal of the second logic port becomes,

W ₂＝[00w ₂w ₂00w ₂w ₂00w ₂-w ₂00w ₂w ₂]。

Step 808: the phase symbol changing the weighting weights of some antennas in described 4th group of antenna, be the 3rd polarised direction with the direction of the signal making described 4th group of antenna synthesis, described 3rd polarised direction is contrary with described first polarised direction;

In the present embodiment, because described first polarised direction is that upper right is pointed in lower-left, then described 3rd polarised direction is that upper right points to lower-left, therefore, need the phase symbol of antenna 7 and antenna 8 to change, and the phase symbol of antenna 15 with an antenna in antenna 16 is changed.

Suppose, change the phase symbol of antenna 7, antenna 8, antenna 16, then the weighting weight matrix of the signal of the second logic port becomes further,

W ₂＝[00w ₂w ₂00-w ₂-w ₂00w ₂-w ₂00w ₂-w ₂]。

Step 809: adopt the weights that in described 16 antennas, each antenna is corresponding to send the signal of described first logic port and the signal of described second logic port.

Figure 11 is the isoboles of the application for the signal of the first logic port in the signaling method embodiment 2 of multiple antennas.As shown in figure 11, after equivalence, the signal of the first logic port is the signal P of the first polarised direction ₁₁with the signal P of the second polarised direction ₁₂.

Figure 12 is the isoboles of the application for the signal of the second logic port in the signaling method embodiment 2 of multiple antennas.As shown in figure 12, after equivalence, the signal of the first logic port is the signal P of the first polarised direction ₂₁with the signal P of the 3rd polarised direction ₂₂.

Equivalent signal in Figure 11 is synthesized further, the first logic port signal upwards can be obtained, the equivalent signal in Figure 12 is synthesized further, the second logic port signal to the right can be obtained.Therefore, the equivalent signal of the first logic port after final synthesis and the equivalent signal of the second logic port, both are mutually orthogonal.

In sum, in the present embodiment, by the weighting weight w that the signal that obtains the first logic port is corresponding ₁, the weights of corresponding for the signal of the first logic port 8 antennas are all set to w ₁, obtain the weighting weight w that the signal of the second logic port is corresponding ₂, the weights of corresponding for the signal of the second logic port 8 antennas are all set to w ₂; Changing the phase symbol of the weighting weights of some antennas in described first group of antenna, is described first polarised direction with the direction of the signal making described first group of antenna synthesis; Changing the phase symbol of the weighting weights of some antennas in described 3rd group of antenna, is described second polarised direction with the direction of the signal making described 3rd group of antenna synthesis; Changing the phase symbol of the weighting weights of some antennas in described second group of antenna, is described first polarised direction with the direction of the signal making described second group of antenna synthesis; Change the phase symbol of the weighting weights of some antennas in described 4th group of antenna, be the 3rd polarised direction with the direction of the signal making described 4th group of antenna synthesis, described 3rd polarised direction is contrary with described first polarised direction; The equivalent signal of the equivalent signal of the first logic port and the second logic port can be made mutually orthogonal, and then the mutual interference that the signal reducing the Different Logic port that multiple antenna sends simultaneously produces when being received by subscriber equipment.

In practical application, in order to make the power of the signal that dual polarized antenna sends as far as possible large, reaching the state that power is completely sent out, described w can be made ₁with w ₂value be 1.
