Embodiment

Determined current order of cables, the order of cables with current order of cables and design mates then, can know just whether order of cables connects correctly.Therefore determine accurately automatically that current order of cables is the key of technology.For dual-polarized antenna array, the antenna order of cables of each polarization that may determine all is correct, but with two groups of order of cables combinations, then may make a mistake.For example, two groups of actual order of cables of dual-polarized antenna array are 1234 and 5678, based on the symmetry of aerial array, think that definite result 12345678 all conforms to actual with 87654321.Two groups of order of cables of determining are combined the order of cables 12348765 or 43215678 that then may obtain mistake.For addressing this problem, the embodiment of the invention determines by the relation between the pairing arrival bearing of order of cables who judges two groups of poliarizing antennas whether order of cables is correct.

Referring to Fig. 1, the main method flow process of the order of cables of definite dual-polarized antenna array is as follows in the present embodiment:

Step 101: the signal that terminal sends is sampled.This process comprises offset position and sampling interval is set; According to offset position that is provided with and sampling interval the signal that terminal sends is sampled.Initial sampling location when wherein, offset position is meant signal sampling.Sampling interval was meant the time interval in the signal sampling process.

Step 102: according to the order of cables of two groups of antenna correspondences in the definite respectively dual-polarized antenna array of sampled signal, the corresponding one group of antenna of one of them polarised direction.

Step 103: judge whether the proportionate relationship between the corresponding respectively arrival bearing of two polarised directions satisfies preset condition, if, then the order of cables of Que Dinging is correct, order of cables sequential combination with two groups of definite antennas, obtain the actual order of cables of dual-polarized antenna array, otherwise the order of cables mistake of determining.

In step 102, determine that the detailed process of order of cables of every group of antenna correspondence is as follows:

Sampled signal comprises a plurality of users' that dual-polarized antenna array receives signal, k user's channel estimate matrix H in the structure sampled signal ^(k), then the channel estimate matrix of two groups of poliarizing antennas is as shown in Equation 1:

Formula 1

Wherein, Ka is the antenna number of dual-polarized antenna array, and every group of antenna number is Ka/2, and ω is that channel estimation window is long, h _iBe i tapping channel estimated value of antenna channel estimated result, i=1... ω.

According to the channel estimate matrix H that obtains ^(k)Determine the space covariance matrix of two groups of antennas, two covariance matrixes that obtain as shown in Equation 2:

$R_1^{\left(k\right)}=H_1^{\left(k\right)}.{\left(H_1^{\left(k\right)}\right)}^H$ Formula 2

$R_2^{\left(k\right)}=H_2^{\left(k\right)}.{\left(H_2^{\left(k\right)}\right)}^H$

Wherein, () ^HThe conjugate transpose of representing matrix.

Construct the weight coefficient matrix of two groups of antennas, as shown in Equation 3:

$W_1=\left(\begin{array}{cccc}1& e^{-j\frac{2\mathrm{\πd}}{\mathrm{\λ}}\sin \left(\mathrm{\θ}\right)}& ...& e^{-j\frac{2\mathrm{\πd}}{\mathrm{\λ}}}\end{array}(\mathrm{K\α}/2-1)\sin \left(\mathrm{\θ}\right)\right)$ Formula 3

$W_2=\left(\begin{array}{cccc}1& e^{-j\frac{2\mathrm{\πd}}{\mathrm{\λ}}\sin \left(\mathrm{\θ}\right)}& ...& e^{-j\frac{2\mathrm{\πd}}{\mathrm{\λ}}}\end{array}(\mathrm{K\α}/2-1)\sin \left(\mathrm{\θ}\right)\right)$

Beam space is divided into L zone uniformly, and L is 360 in the present embodiment, and then first group of antenna is at every kind of each zone with reference to the received power under the order of cables as shown in Equation 4:

${\mathrm{\σ}}_{1,l}^2\left(m\right)={\left(W_1^l\left(m\right)\right)}^H{R}_1{W}_1^l\left(m\right)$ Formula 4

Wherein, l represents the 1st zone, l=1...L.M=1,2 ...,

The m kind of representing one group of antenna is with reference to order of cables.Because from Ka root antenna, select Ka/2 root antenna to have

Plant possibility, and the position grouping of every Ka/2 root antenna self inside has also

Plant possibility, so the reference order of cables of one group of antenna is always total Kind.

Because the corresponding arrival bearing in each zone, then by formula 4 as can be known, each received power correspondence a kind of with reference to order of cables of an arrival bearing and one group of antenna.

One group of antenna has Plant with reference to order of cables, but its actual order of cables should have only a kind of.Do not know actual order of cables at present, therefore need all reference order of cables be traveled through, obtain every kind of received power with reference to the order of cables correspondence.In the present embodiment, maximal received power corresponding reference order of cables in all received powers of one group of antenna correspondence is defined as the order of cables of this group antenna, the arrival bearing of this maximal received power correspondence is arrival bearing of this group antenna.Wherein, if L is less than 360, corresponding arrival bearing's scope in each zone then, then the arrival bearing of each received power correspondence is the mean value of all arrival bearings in the zone of its correspondence.

After having determined the order of cables of two groups of antennas, in step 103, judge whether the relation between the corresponding respectively arrival bearing of two polarised directions satisfies

If, then the order of cables with two groups of antennas connects the order of cables that just can obtain correct dual-polarized antenna array from beginning to end, otherwise the order of cables backward of arbitrary group of antenna is arranged, and the order of cables with two groups of antennas connects the order of cables that just can obtain correct dual-polarized antenna array from beginning to end again.Wherein η is default thresholding,

With

Referring to Fig. 2, determine that according to maximal received power the order of cables of the order of cables of antenna determines that the realization flow of method is as follows in the present embodiment:

Step 201: signal is sampled, and obtain a plurality of sampled signals.

Step 202: at each sampled signal, determine two groups of antennas in each subregion all with reference to the received power of order of cables correspondence.

Step 203:, determine the maximal received power in the received power of two groups of antenna correspondences respectively at each sampled signal.One group of antenna all with reference to the All Ranges of order of cables in corresponding maximal received power.Then, about a plurality of sampled signals, one group of corresponding a plurality of maximal received power of antenna.

Step 204: the maximal received power of determining two groups of antennas is pairing with reference to order of cables.The pairing order of cables that is this group antenna correspondence with reference to order of cables of this maximal received power.

Step 205: the pairing arrival bearing of maximal received power who determines two groups of antennas.The pairing arrival bearing of this maximal received power is the arrival bearing of this group antenna correspondence.

Through above-mentioned flow process,, obtain a plurality of correct order of cables at two groups of antennas about a plurality of sampled signals.If a plurality of correct order of cables are identical, then this order of cables is the actual order of cables of dual-polarized antenna array.If a plurality of correct order of cables are incomplete same, then need therefrom to determine final correct order of cables, continue step 207.

Step 207: judge in a plurality of correct order of cables whether identical order of cables is arranged,, then continue step 208, otherwise finish this flow process, can further turn back to step 201, carry out signal sampling again if having.When carrying out signal sampling once more, can adjust offset position and sampling interval.

Step 208: determine that the maximum order of cables of same number is final correct order of cables, is the actual order of cables of dual-polarized antenna array.

In step 208, judge whether the maximum order of cables of same number is multiple, if, determine that then this result who determines is invalid, turn back to step 201, carry out signal sampling again, otherwise determine that this kind order of cables is final correct order of cables.

Wherein, step 204 can be carried out between step 206 and 207.

Consider interference of noise, the order of cables that the order of cables of maximal received power correspondence is not necessarily actual, then the following examples will be determined actual order of cables in n received power corresponding reference cable order in the past.

Referring to Fig. 3, determine that according to the big received power of preceding n the order of cables of the order of cables of antenna determines that the realization flow of method is as follows in the present embodiment:

Step 302: at each sampled signal, determine two groups of antennas in each subregion all with reference to the received power of order of cables correspondence.

Step 303: at each sampled signal, n is individual than big received power in the received power of definite two groups of antenna correspondences respectively.This n is big, and received power all is not less than other received power, be by descending sort in the resulting sequence to received power before n received power.N is default number thresholding, and value in the present embodiment is 200.

Step 304: determine that n corresponding respectively received power of two groups of antennas is pairing with reference to order of cables.The pairing order of cables that is this group antenna correspondence with reference to order of cables of this n received power.

Step 305: determine n the pairing arrival bearing of received power that two groups of antennas are corresponding respectively.Maximum arrival bearing among the pairing arrival bearing of this n received power is the arrival bearing of this group antenna correspondence.

Step 306:, judge whether the relation between the arrival bearing of two groups of antenna correspondences satisfies preset condition at each sampled signal

If then the order of cables of two groups of antenna correspondences that obtain about this sampled signal is correct, otherwise with the wherein reverse arrangement of order of cables of one group of antenna correspondence, promptly obtains correct order of cables.

At each sampled signal, every group of corresponding n order of cables of antenna, for a plurality of sampled signals, every group of antenna correspondence overlapped order of cables more, whenever is with n order of cables.Need below from these many cover order of cables, to determine that an order of cables is final correct order of cables.

Step 307: judge in a plurality of correct order of cables whether identical order of cables is arranged,, then continue step 308, otherwise finish this flow process, can further turn back to step 301, carry out signal sampling again if having.When carrying out signal sampling once more, can adjust offset position and sampling interval.

Step 308: determine that the maximum order of cables of same number is final correct order of cables, is the actual order of cables of dual-polarized antenna array.

In step 308, judge whether the maximum order of cables of same number is multiple, if, determine that then this result who determines is invalid, turn back to step 301, carry out signal sampling again, otherwise determine that this kind order of cables is final correct order of cables.

The received power of the reference order of cables correspondence that has may all not come maximal received power in every sets of data, but may be subjected to factor affecting such as noise, its received power is the 2nd or the 3rd big received power mostly, and such reference order of cables may be final correct order of cables.Present embodiment is exactly the past n middle maximum order of cables of same number of selecting, to determine finally correct order of cables.

By above-mentioned two embodiment as can be seen, from maximal received power or preceding n more high-power corresponding reference order of cables, determine final correct order of cables, promptly determine final correct order of cables from two kinds of approach.If the order of cables of determining from these two kinds of approach is identical, the maximum pairing received power of order of cables of same number in the individual more high-power corresponding reference order of cables of n promptly, whether its number of times as maximal received power is higher than the number of times of the received power of other correct order of cables correspondence as maximal received power, think that then this order of cables is actual order of cables, otherwise determine that this result who determines is invalid, need carry out signal sampling again.
