Below in conjunction with Figure of description, the embodiment of the present invention is elaborated.
The process in Fig. 1 provides for the embodiment of the present invention location interference source, this process comprises the following steps:
S101: according to the signal that each collection point gathers, determine interference signal that described each collection point gathers corresponding come wave angle.
Determine interference signal that each collection point gathers corresponding come wave angle the time, working frequency range according to current mobile communication equipment, filter out the interference signal that described interference band is caused interference in the signal that each collection point gathers, and the interference signal that will filter out from each collection point is carried out quantification treatment, according to each interference signal after quantification treatment, determine interference signal that described each collection point gathers corresponding come wave angle.

S103: determine the attribute information of each interference signal in each collection point, and according to the attribute information of each interference signal in described each collection point of determining, and the described interference source path locus of determining, determine the position of interference source.
The attribute information of each interference signal comprises time-domain information, frequency domain information or the amplifier distortion information etc. of each interference signal.
The position of described definite interference source specifically comprises: time-domain information, frequency domain information or the amplifier distortion information of adding up each interference signal in each collection point, the intersection point that will have interference source path locus corresponding to the interference signal of identical time-domain information, frequency domain information or amplifier distortion information is as the position of interference source.
When drawing the interference source path locus, determine the position of each collection point according to the latitude and longitude information of each collection point on map, according to the orientation angle that comes wave angle, determine the interference source path locus.Because the path locus of the interference source of determining is a ray, certain on this ray a bit may be the position at interference source place.The particular geographic location of this point can be determined according to the latitude and longitude information of the intersection point of the interference source path locus of determining during the position in concrete location interference source, with the position of this geographical position as the interference source place.
Due in embodiments of the present invention for each collection point; when having determined through after the interference source path locus of this collection point; can there be intersection point in the interference source path locus that different acquisition point is corresponding, generally with the intersection point of this interference source path locus position as interference source.And because interference signal can be received the building refraction, or the impact of signal stack, there is false position of interference source in the intersection point of the interference source path locus of therefore determining.the embodiment of the present invention is in order effectively to remove false interference source, for each collection point, determine through after the interference source path locus of this collection point, added up the time domain of each interference signal of each collection point collection, the attribute informations such as frequency domain information or amplifier distortion information, owing to having identical time domain, the interference signal of the attribute informations such as frequency domain information or amplifier distortion information may be just the interference signal that same interference source sends, and will have identical time-domain information, the intersection point of the interference source path locus that the interference signal of frequency domain information or amplifier distortion information is determined, position as interference source, thereby effectively eliminated the interference that the refraction of signal is caused due to building, and the interference that between the disturbance source signal, stack produces, and then precision and the accuracy of interference source location have been improved.
Carry out in embodiments of the present invention the terminal of interference source location and can carry out in real time the location of interference source, also can carry out the location of interference source when determining to be interfered to current mobile communication equipment, concrete implementation process can be carried out flexible choice as required.Wherein whether current mobile communication equipment be interfered can be according to current mobile communication equipment received signal strength indicator (Received Signal Strength Indicator, RSSI) whether less than the threshold value of setting, judge, when current mobile communication equipment received signal strength indicator during less than setting threshold, determine that current mobile communication equipment is interfered, otherwise, determine that current mobile communication equipment is not interfered, current mobile communication equipment can be the base station.The terminal of carrying out interference source location can be the base station, the other-end equipment that also can close on for having smart antenna and current mobile communication equipment.
Can pass through the smart antenna collection signal in embodiments of the present invention, because smart antenna may comprise a plurality of passages, for example for the time-division that comprises 8 passages (Time Division, TD) smart antenna, adopt the smart antenna collection signal in each collection point, and after having obtained the signal that each collection point gathers, because needs are determined the mobile communication equipment of work at present frequency range caused the interference source of interference, just understand the phase mutual interference and only have between the signal of similar frequency bands.therefore need to be according to the working frequency range of current mobile communication equipment, be for example global system for mobile communications (Global System for Mobile Communications, GSM) frequency range, Digital Cellular System (Digital Cellular System, DCS) frequency range or TD frequency range etc., filter out the interference signal that the work at present frequency range is caused interference in the signal that each smart antenna collects by each passage, namely will filter out with the signal of the working frequency range similar frequency bands of current mobile communication equipment in the signal that each passage collects, with this signal that filters out as mobile communication equipment before deserving being caused the interference signal of interference.
After the interference signal of this frequency range filtered out in each passage, because the interference signal of this each passage that filters out is analog signal, the demand of processing in order to satisfy data need to be processed the interference signal that each passage filters out and obtain digital signal.The process of this processing comprises: the analog radio frequency interference signal of this frequency range of obtaining after filtering in each passage is down-converted to intermediate-freuqncy signal, to the digital signal that the intermediate-freuqncy signal that obtains after each passage frequency conversion is sampled, thereby quantification treatment obtains corresponding each passage, this analog signal conversion is that the process of digital signal does not here just describe in detail.
The signal that each passage by smart antenna collects, probably there is nonsynchronous problem in the difference that is subject to the collecting device antenna oscillator, in order to guarantee the accuracy of interference source location, each passage of smart antenna need to be compensated processing by the signal that antenna oscillator receives, the signal that each passage is gathered is synchronous, can carry out quantification treatment to each interference signal in the invention process after, the digital signal of each passage that obtains compensates.
The compensation method of adopting in embodiments of the present invention comprises: passage consistency error compensation, asynchronous compensation of sample time and the inconsistent compensation of frequency response etc.Wherein passage consistency error compensation by the acquisition performance of each passage in smart antenna is tested, is determined the otherness of interchannel, according to this otherness, the signal that respective channels receives is carried out passage consistency error compensation.Equally when the signal to each passage carries out sample time asynchronous compensation, determine the otherness in each passage sample time, according to this otherness, the signal of respective channel is carried out asynchronous compensation of sample time.when adopting TD smart antenna receiver signal, due to the TD smart antenna according to transmitting and receiving TD frequency band signals design, therefore this TD smart antenna is when receiving the signal of other frequency ranges, for example during the signal of GSM frequency range, its frequency response, difference can appear in the phase response performance, be specifically as follows when receiving the signal of other frequency ranges, the electrical characteristic of this smart antenna is different from the electric property that receives the TD frequency band signals, therefore, need to test the electric property that smart antenna gathers other frequency band signals, according to test result, the electric property that this smart antenna is gathered other frequency band signals compensates, obtain the signal of each passage of obtaining after electric property compensation.
The interference signal that gathers according to each passage of each smart antenna after compensation, adopt the spatial frequency spectrum algorithm, for example MUSIC algorithm or ESPRIT algorithm, arrive the time delays in different intelligent antenna a period of time according to the signal of same interference source, determine the interference source signal of corresponding each smart antenna collection corresponding come wave angle, wherein this to come wave angle be the incoming wave angle of the signal of intensity maximum in the interference source signal, this angle is the angle of this interference signal and smart antenna normal direction.
Above-mentioned interference signal to the smart antenna collection is processed, and definite mode of coming wave angle corresponding to interference signal of determining corresponding each smart antenna also has open in the prior art, when the interference signal of having determined corresponding each smart antenna collection corresponding come wave angle the time, can be according to the position of each smart antenna, and this comes the direction of wave angle, determine take this smart antenna position as end points, the incoming wave angular direction is the ray of direction, namely determines the interference path track through this collection point, smart antenna place.Due to after the interference path track determines, can there be intersection point in the interference source path locus that should the ray take each collection point as end points consists of, and this intersection point can be used as the location point at interference source place.
But due to the impact that has the disturbing factors such as building refraction in mobile communications network, thereby make the position of definite interference source inaccurate, the position at the interference source place of namely determining may be dummy location, in embodiments of the present invention in order effectively to determine the actual position of interference source in the position of interference source of the dummy location that comprises interference source of determining, in embodiments of the present invention can be by analyzing the attribute information of the interference signal that in each collection point, each passage of smart antenna collects, determine the actual position of interference source, this process specifically comprises:
Analyze the attribute informations such as time-domain information, frequency domain information or amplifier distortion information of the interference signal of each passage collection that obtains after each smart antenna compensation, because have between the signal of identical attribute information and have the attribute informations such as identical time-domain information, frequency domain information or amplifier distortion information, be that identical signal is having identical variation characteristic on frequency domain He on time domain, and the impact that the signal of same interference source is subject to identical amplifier distortion also have identical variation characteristic.fluctuation has appearred in its a certain moment in time domain of the first interference signal that receives when the first a certain passage of smart antenna, for example this interference signal is constantly recessed at this, with this first smart antenna receiver to this first interference signal give the identification information that is different from other interference signals, the second interference signal that receives when the second a certain passage of smart antenna also the moment of this in time domain recessed, and recessed amplitude is identical in this recessed amplitude constantly with the first interference signal, also give the identification information identical with the first interference signal with this second interference signal that receives of this second smart antenna, think that namely the first interference signal and the second interference signal have identical attribute information, the first interference signal and the second interference signal can be thought the interference signal that sends out for same interference source.Adopt said method with each smart antenna receiver to each interference signal give identification information.
The above-mentioned definite variation characteristic of interference signal on time domain or frequency domain, can be as required step-up error scope flexibly, for example the fluctuation of a direction has appearred in the first interference signal of a certain smart antenna collection in the position of 20MHz, the second interference signal of another smart antenna collection unidirectional fluctuation occurred in the position of 20.56MHz, when its 1MHz of error range of arranging, two first interference signals and the second interference signal can be thought the interference signal of sending for same interference source, give same identification information with two interference signals.
When determining the frequency information of the signal that each interference source path locus is corresponding, this signal is carried out fast fourier transform (Fast Fourier Transform, FFT), obtain the spectral characteristic of this signal, spectral characteristic according to this signal, namely determine the performance characteristic of each interference signal in frequency domain, determine the frequency domain information of this signal.
determining through after the interference source path locus of collection point, smart antenna place, have intersection point between interference source path locus corresponding to the interference signal that gathers due to different acquisition point, the position that each intersection point is corresponding may be the position of interference source, in embodiments of the present invention because the signal with same alike result information has identical identification information, and the interference signal that the interference signal with same alike result information may be sent for same interference source, the position of the intersection point of the interference source path locus that therefore interference signal with same identification information can be determined, position as the interference source place.
Above-mentioned implementation process, localization method for interference source, when determining the attribute information of the interference signal that each smart antenna gathers, the accuracy of locating in order to ensure interference source only needs for a kind of attribute information, namely determine a kind of attribute information of the interference signal of each smart antenna collection point collection, for example determine the frequency domain information of each interference signal, determine that each interference signal is to identification information that should attribute information, according to the different identification information of interference signal, determine the actual position of interference source.Can certainly adopt by determining the two kinds or more of attribute informations of the interference signal that each smart antenna gathers, carry out interference source and locate.
definite process of position of interference source shown in Figure 2 for example, comprise two collection points at Fig. 2, two interference source path locus have been determined by each collection point, the first interference source path locus 11 that the first collection point is corresponding and the second interference source path locus 12, corresponding the 3rd interference source path 21, the second collection point and the 4th interference source path locus 22, during the attribute information of the interference signal that wherein gathers at the smart antenna of determining to be positioned at each collection point, determine that in the first collection point, the first interference signal has the first time domain attribute information, in the first collection point, the second interference signal has the first frequency domain attribute information, corresponding the first interference source path locus 11 in incoming wave angular direction that this first interference signal is corresponding, corresponding the second path locus 12 in incoming wave angular direction that the second interference signal is corresponding, determine that in the second collection point, the 3rd interference signal has the first time domain attribute information, in the second collection point, the 4th interference signal has the first frequency domain attribute information, corresponding the 3rd interference source path locus 21 in incoming wave angular direction that the 3rd interference signal is corresponding, corresponding the 4th path locus 22 in incoming wave angular direction that the 4th interference signal is corresponding.
when determining position of interference source according to the interference source path locus of determining, because the 3rd interference signal in the first interference signal in the first collection point and the second collection point has identical time domain attribute information, therefore the intersection point in the interference source path determined, incoming wave angular direction corresponding to these two interference signals can be defined as the first position of interference source position point, simultaneously in the first collection point in the second interference signal and the second collection point the 4th interference signal have identical frequency domain attribute information, therefore the intersection point in the interference source path determining to eat, incoming wave angular direction corresponding to these two interference signals can be defined as the location point at the second position of interference source place, as shown in Figure 2.
in the embodiment of the present invention when when determining position of interference source, in order to reduce amount of calculation, improve the efficient of interference source location, can select to carry out the collection point of interference source location in the collection point at smart antenna place, according to the collection point of selecting, determine through this each collection point interference source routing information, and the attribute information according to each interference signal in the collection point of this selection, determine the position of interference source, because the collection point of selecting is less, therefore can reduce the amount of calculation of interference source location, and improve the efficient of interference source location, when selecting the collection point, distance according to collection point and mobile communication equipment, when perhaps definite according to accuracy of each collection point collection signal etc., can also be when reducing interference source location Calculation amount, improve the accuracy of interference source location, here just do not give unnecessary details one by one.
in the embodiment of the present invention when the position in location interference source, according to the interference source path locus through the collection point of determining, and the attribute information of signal corresponding to each interference source path locus, the position that will have the intersection point of the interference source path locus that the interference signal of same alike result information determines, position as interference source, due to the attribute information of having considered the interference signal that each interference source path locus is corresponding, and the interference signal of only having same interference source to produce and pass through identical path just may have identical attribute information, therefore, the embodiment of the present invention has effectively been got rid of building when the location interference source, or the interference of signal stack generation, thereby improved the accuracy of interference source location.
