It, can be there are many phase for direction first polarization direction for the signal for synthesizing first group of antenna Sign modification mode.Such as, thus it is possible to vary the phase symbol of the signal of antenna 9 makes the signal of antenna 9 and the signal side of antenna 10 To on the contrary, thus it is possible to vary the phase symbol of the signal of antenna 10 makes sense phase of the signal of antenna 10 with antenna 9 Instead.

Assuming that changing the phase symbol of the signal of antenna 10, then the weighting weight matrix of the signal of the first logic port Become,

W₁=[w₁ w₁ 0 0 w₁ w₁ 0 0 w₁ -w₁ 0 0 w₁ w₁ 0 0]

Step 806: changing the phase symbol of the weighting weight of some antennas in the third group antenna, so that the third The direction of the signal of group antenna synthesis is second polarization direction；

It is identical as step 805 principle, it is assumed that change the phase symbol of the signal of antenna 5, then the signal of the first logic port Weighting weight matrix be further changed to,

W₁=[w₁ w₁ 0 0 -w₁ w₁ 0 0 w₁ -w₁ 0 0 w₁ w₁ 0 0]

Step 807: changing the phase symbol of the weighting weight of some antennas in second group of antenna, so that described second The direction of the signal of group antenna synthesis is first polarization direction；

Sent in second group of antenna and the 4th group of antenna be the second logic port signal.

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

Identical as step 805 principle, the phase symbol for changing antenna 11 or antenna 12 can make second group of antenna The direction of the signal of synthesis is first polarization direction.

It is assumed that changing the phase symbol of antenna 11, then the weighting weight matrix of the signal of the second logic port becomes,

W₂=[0 0 w₂ w₂ 0 0 w₂ w₂ 0 0 w₂ -w₂ 0 0 w₂ w₂]。

Step 808: changing the phase symbol of the weighting weight of some antennas in the 4th group of antenna, so that the described 4th The direction of the signal of group antenna synthesis is third polarization direction, and the third polarization direction is opposite with first polarization direction；

In the present embodiment, since first polarization direction is that upper right is directed toward in lower-left, then the third polarization direction is the right side Upper direction lower-left, therefore, it is necessary to change the phase symbol of antenna 7 and antenna 8, and by one in antenna 15 and antenna 16 The phase symbol of antenna changes.

It is assumed that changing the phase symbol of antenna 7, antenna 8, antenna 16, then the weighting weight of the signal of the second logic port Matrix is further changed to,

W₂=[0 0 w₂ w₂ 0 0 -w₂ -w₂ 0 0 w₂ -w₂ 0 0 w₂ -w₂]。

Step 809: first logic port is sent using the corresponding weighting weight of antenna each in 16 antennas Signal and second logic port signal.

Figure 11 be the application for multiple antennas signaling method embodiment 2 in the first logic port signal it is equivalent Figure.As shown in figure 11, the signal of equivalent rear first logic port is the signal P of the first polarization direction₁₁With the second polarization direction Signal P₁₂。

Figure 12 be the application for multiple antennas signaling method embodiment 2 in the second logic port signal it is equivalent Figure.As shown in figure 12, the signal of equivalent rear first logic port is the signal P of the first polarization direction₂₁With third polarization direction Signal P₂₂。

Equivalent signal in Figure 11 is further synthesized, available the first upward logic port signal will be in Figure 12 Equivalent signal further synthesize, available the second logic port signal to the right.Therefore, the first logic after final synthesis The equivalent signal of the equivalent signal of port and the second logic port, the two are mutually orthogonal.

In conclusion in the present embodiment, by the corresponding weighting weight w of signal for obtaining the first logic port₁, by first The weight of corresponding 8 antennas of the signal of logic port is disposed as w₁, obtain the corresponding weighting of signal of the second logic port Weight w₂, the weight of corresponding 8 antennas of the signal of the second logic port is disposed as w₂；Change in first group of antenna The phase symbol of the weighting weight of some antennas, so that the direction of the signal of first group of antenna synthesis is first polarization Direction；The phase symbol for changing the weighting weight of some antennas in the third group antenna, so that the third group antenna synthesizes Signal direction be second polarization direction；Change the phase symbol of the weighting weight of some antennas in second group of antenna Number, so that the direction of the signal of second group of antenna synthesis is first polarization direction；Change in the 4th group of antenna The phase symbol of the weighting weight of some antennas, so that the direction of the signal of the 4th group of antenna synthesis is third polarization side To the third polarization direction is opposite with first polarization direction；It can make the equivalent signal of the first logic port and the The equivalent signal of two logic ports is mutually orthogonal, and then reduces the signal for the Different Logic port that mutiple antennas is sent simultaneously in quilt What user equipment generated when receiving interferes with each other.
