Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The object of the embodiment of the present invention is to provide a kind of method reducing the interference signal of mobile communication, to solve in prior art the interference signal produced in mobile communication, when such as screen or other functional module produce interference signal, normally first carry out coupling sensitivity test and find interference source, and then process according to the interference source found, namely be generally after having problems, then according to trouble-shoots interference source, more whether dealt with problems by various Improving Measurements checking.The shortcoming of this mode is, the cycle of exclusive PCR is long, in exclusion process, need labor intensive.
For the cycle when interference signal solving mobile communication in prior art is got rid of is long and the defect of labor intensive, the invention provides a kind of method reducing the interference signal of mobile communication, described method comprises: the MIPI frequency in the parameter that the functional module in acquisition equipment configures; According to the MIPI frequency obtained, carry out scaling down processing according to the first ratio preset, obtain the first fundamental frequency; Process of frequency multiplication is carried out to the first fundamental frequency, obtains the frequency after multiple frequency multiplication; The channel of the frequency search frequency multiplication in the frequency range used after, and in the channel the frequency of the frequency multiplication found is carried out filtration treatment.
By the MIPI frequency in the parameter of the functional module configuration in acquisition equipment, and process of frequency multiplication is again carried out after frequency division to it, and to searching the frequency of frequency multiplication in the frequency range used, and the frequency of the frequency multiplication of searching in the frequency range used carries out filtration treatment, thus can interference that effectively functional module is brought in minimizing equipment, while saving labour, also improve the promptness to interference signal process greatly.Specifically be described below in conjunction with accompanying drawing.
Embodiment one:
Fig. 1 shows the realization flow of the method for the interference signal of the minimizing mobile communication that first embodiment of the invention provides, and details are as follows:
In step S101, the MIPI frequency in the parameter that the functional module in acquisition equipment configures.
Concrete, the equipment described in the embodiment of the present invention can be the communication terminal such as smart mobile phone, panel computer.Because communication system in equipment is for ensureing reliably carrying out of data and voice, need to get rid of timely the interference signal that other functional module is brought.
And the source of current interference signal, each functional module mainly in equipment, comprises display panel module, camera module, sensor assembly and key-press module etc., if channel is interfered, may be produced by wherein partial function module.
In embodiments of the present invention, by reading in each functional module configuration parameter MIPI, (English full name is MobileIndustryProcessorInterface, Chinese full name is mobile Industry Processor Interface) frequency, described MIPI frequency can be determined after the electric circuit diagram design sizing of equipment, this MIPI frequency can be read in the memory of equipment, also can receive the MIPI frequency inputted by user.
Such as, the MIPI circuit number for display screen is given value, and as constant storage assigned address in a device, the present invention only needs the position of specifying at this to read MIPI frequency corresponding to MIPI circuit number.
In step s 102, according to the MIPI frequency obtained, carry out scaling down processing according to the first ratio preset, obtain the first fundamental frequency.
Concrete, when carrying out scaling down processing to the MIPI frequency obtained according to the first ratio in the embodiment of the present invention, choosing of described first ratio can pre-set, and also according to MIPI circuit number, can determine the interference interval of MIPI, select corresponding first ratio value.Such as the first ratio value can be selected to carry out 1/4 frequency division to MIPI frequency according to circuit number accordingly, or carries out 1/12 frequency division to MIPI frequency, obtains the first fundamental frequency.
Wherein determine to disturb the method at interval to be described as follows according to MIPI circuit number:
When the rgb signal parallel transmission on MIPI circuit, when MIPI circuit number is 2 groups, once repeating appears in same color component (R or G or B) every 3 clock cycle;
Line0:RBGRBG
Line1:GRBGRB
When MIPI circuit number is 3 groups, once repeating appears in same color component (R or G or B) every 1 clock cycle;
Line0:RRR
Line1:GGG
Line2:BBB
When MIPI circuit number is 4 groups, once repeating appears in same color component (R or G or B) every 3 clock cycle.
Line0:RGBRGB
Line1:GBRGBR
Line3:BRGBRG
Line4:RGBRGB
When MIPI circuit number is 5 groups, once repeating appears in same color component (R or G or B) every 3 clock cycle.
Line0:RBGRBG
Line1:GRBGRB
Line3:BGRBGR
Line4:RBGRBG
Line5:GRBGRB
By that analogy.
And 2 color component data (rising edge of a square-wave cycle and trailing edge) can be transmitted within each clock cycle, each color component data comprises 8 bytes.So when color component data every 3 clock cycle repeat one time, interference interval=MIPI frequency * 2/ (8*3)=MIPI frequency/12; When color component data every 1 clock cycle repeats one time, interference interval=MIPI frequency * 2/ (8*1)=MIPI frequency/4.
So when MIPI circuit is 2 groups, interference interval is 1/12 frequency division of MIPI frequency; When MIPI circuit is 3 groups, interference interval is 1/4 frequency division of MIPI frequency; When MIPI circuit is 4 groups, interference interval is 1/12 frequency division of MIPI frequency, and when MIPI circuit is 2 groups, interference interval is 1/4 of MIPI frequency.By that analogy.
If the MIPI frequency that multiple functional modules that equipment comprises are corresponding different, so can carry out corresponding scaling down processing to multiple MIPI frequency simultaneously, obtain multiple first fundamental frequency.
In step s 103, process of frequency multiplication is carried out to the first fundamental frequency, obtain the frequency after multiple frequency multiplication.
In embodiments of the present invention, if set the frequency range that uses as [a, b], so, described process of frequency multiplication is carried out to the first fundamental frequency, obtains the frequency step after multiple frequency multiplication and comprise:
To the first fundamental frequency f1 according to the process of frequency multiplication of carrying out integral multiple from small to large successively, and judge whether the value of the frequency N*f1 after current frequency multiplication is less than the maximum b of the frequency range of use;
If the frequency N*f1 after current frequency multiplication is less than the maximum b of the frequency range of use, then calculate frequency (N+1) the * f1 after frequency multiplication further, until the frequency after frequency multiplication is more than or equal to the maximum of the frequency range of use.
Namely, when carrying out frequency multiplication to the first fundamental frequency, the multiple of the first fundamental frequency is increased gradually.Such as select natural number from small to large 1,2,3,4,5 ... N, the Clock Multiplier Factor successively as the first fundamental frequency carries out frequency multiplication.Limited the calculation times of frequency multiplication by the maximum of scope of the frequency used, frequency multiplication computing time can be saved.
Certainly, in execution mode as further optimization of the present invention, the ratio that can also be obtained by the minimum value of the frequency range of use and the first fundamental frequency determines minimum Clock Multiplier Factor, and namely minimum Clock Multiplier Factor is for being greater than or equal to the smallest positive integral of described ratio (ratio that the minimum value of the frequency range of use and the first fundamental frequency obtain).The ratio that the minimum value of the frequency range such as used and the first fundamental frequency obtain is 3.14, and so minimum Clock Multiplier Factor selects 4, thus can reduce amount of calculation further.
In step S104, the channel of the frequency search frequency multiplication in the frequency range used after, and in the channel the frequency of the frequency multiplication found is carried out filtration treatment.
After frequency after obtaining multiple frequency multiplication, by the frequency range used, the frequency obtained is screened, select the frequency belonged in the frequency range of described use.
Wherein, the frequency range of described use, comprises the current frequency range just used, and other communication module in equipment, or the frequency range corresponding to communication standard.So, the channel step of the frequency after searching frequency multiplication in the described frequency range using comprises:
Obtain the current frequency range used in modulator-demodulator, and the frequency range that the communication module that comprises of equipment uses;
Frequency search frequency multiplication respectively in the frequency range of the multiple uses obtained after.
Such as, the frequency range of the downstream frequency of GSM900 is 925MHz to 959.8MHz, and the frequency range of the upstream frequency of GSM850 is 869.0 – 894.0.When equipment comprises this two kinds of standards, system can to the frequency according to detection, the frequency after whether comprising frequency multiplication is inquired about in above-mentioned two frequency ranges, if comprised, then filtering process is carried out to the information at this frequency place, wherein the mode of filtering process can generate notch filter automatically, the MIPI frequency automatically corresponding to each functional module in equipment by software mode generates notch filter, filtration treatment can be carried out to it when disturbing and producing, thus improve the present invention to while the promptness of interference signal process, also can save labour.

In step S202, according to the MIPI circuit number of display screen, determine first ratio of described MIPI frequency being carried out to frequency division.Described first ratio can the numerical value such as 1/4 or 1/12.
In step S203, according to the frequency range used in equipment, obtain the frequency range used.In the present invention, generally can be used for low frequency frequency range, as GSM850, GSM900 carry out AF panel.The downstream frequency scope of such as GSM900 is 925MHz to 959.8MHz.Carry out carrying out frequency multiplication after frequency division obtains the first fundamental frequency with the first ratio of MIPI frequency, the coefficient of frequency multiplication is selected from small to large successively, such as from 1 times, and 2 times, 3 times ... n doubly.
In step S204, if the frequency after frequency multiplication be less than the frequency range of use be less than value most, then increase the coefficient of frequency multiplication.
In step S205, if the frequency after frequency multiplication is less than the maximum of the frequency range of use, and be greater than the minimum value of the frequency range of use, then record this frequency for interference frequency.
In step S206, if the frequency after frequency multiplication is greater than the maximum of the frequency range of use, then complete the interference frequency search of this frequency range.
