Referring to Fig. 1, the flow signal of mutual interference processing method coexists for a kind of antenna provided by the embodiments of the present application by Fig. 1
Figure.The method is applied in electronic equipment, the method includes：
Step 101, judge with the presence or absence of mutual interference coexists between LTE antenna and WLAN antennas, wherein the LTE antenna is used for
LTE signals are transmitted, the WLAN antennas are used for transmission WLAN signal.If so, perform step 102；If it is not, then perform step
104。
In some embodiments, electronic equipment can be in preset period of time, LTE antenna described in periodic detection and WLAN
It whether there is between antenna and mutual interference coexist.
In some embodiments, electronic equipment can also determine that LTE antenna and WLAN antennas are in running order simultaneously
When, it detects between the LTE antenna and WLAN antennas with the presence or absence of mutual interference coexists.
Wherein, the LTE antenna and WLAN antennas are in running order simultaneously can include the following two kinds state, specifically
For：
(1) LTE mobile data networks use data traffic, WLAN data network be not connected with wireless network access point AP but
Perform active scan；
(2) LTE mobile data networks be in call scene, WLAN data network connection wireless network access point online or
Person performs active scan.
In some embodiments, as shown in Fig. 2, step 101 can be realized by step 1011 to step 1013, specifically
For：
Step 1011, whether the LTE signals and the WLAN signal of WLAN antenna transmissions for judging LTE antenna transmission are adjacent frequency
The signal of section.
Wherein, when LTE antenna and WLAN antennas are in running order simultaneously, the LTE letters of LTE antenna transmission are obtained respectively
Working frequency range number with the WLAN signal of WLAN antenna transmissions.For example, if the working frequency range for getting LTE signals is 2300-
2400MHz, i.e., corresponding working channel are B40, and the working frequency range for getting WLAN signal is 2400-2483.5MHz, it is determined that
The LTE signals of LTE antenna transmission and the signal that the WLAN signal of WLAN antenna transmissions is successive bands, may exist and coexist mutually
It disturbs.For example, if the working frequency range for getting LTE signals is uplink UL:880-915MHz, downlink DL:925-960MHz, i.e., it is corresponding
Working channel for B8, the working frequency range for getting WLAN signal is 2400-2483.5MHz, it is determined that LTE antenna transmission
The WLAN signal of LTE signals and WLAN antenna transmissions is the signal of non-adjacent frequency range, it is not easy to exist and mutual interference coexists.
Step 1012, if the WLAN signal of the LTE signals of LTE antenna transmission and the WLAN antenna transmissions is adjacent
The signal of frequency range then judges the LTE signals with the adjacent channel leakage of the WLAN signal than whether being less than first threshold.
Wherein, adjacent channel leakage ratio (Adjacent Channel Leakage Ratio, ACLR), refers to main channel
The ratio between transmission power and the adjacent or alternate carrier power of radio-frequency channel that measures.It is operated in the antenna system of successive bands
Between mutual interference, be as caused by the imperfection of transmitter and receiver.Transmitter can be generated when emitting useful signal
Out-of-band radiation, adjacent frequency radiation caused by out-of-band radiation includes modulation and band stray radiation.Usually with adjacent channel leakage ratio
ACLR drops into ability in receiver pass-band to weigh adjacent channel transmitting signal, as transmission power in adjacent channel
Record power in the ratio between record power, wherein adjacent channel is equivalent to the normal power for receiving power and being generated with interference signal
The sum of.For receiver while useful signal is received, the interference signal fallen into channel may cause receiver sensitivity
Loss, causes mutual interference.Wherein, if in the case where transmission power is fixed value, the record power in adjacent channel is bigger,
The interference signal for illustrating to fall into adjacent channel is more, it can be said that bright adjacent channel leakage is than smaller, the letter that receiver receives
Number quality is poorer, and interference is bigger.If in the case where transmission power is fixed value, the record power in adjacent channel is smaller, says
The bright interference signal fallen into adjacent channel is smaller, it can be said that bright adjacent channel leakage ratio is bigger, receiver received signal
Quality is better, and interference is smaller.
Step 1013, if adjacent channel leakage ratio is less than first threshold, it is determined that the LTE antenna and WLAN antennas
Between exist mutual interference coexists.
Wherein, only the guaranteed adjacent channel leakage is maintained on first threshold, just can ensure that antenna has received
Whole signal if adjacent channel leakage ratio is less than first threshold, illustrates that antenna cannot receive complete signal, determines
Exist between the LTE antenna and WLAN antennas and mutual interference coexists.
Step 102, the LTE antenna and WLAN antennas are detected and emits signal and another with the presence or absence of a side within the same period
One side receives the situation of signal.If so, perform step 103；If it is not, then perform step 104.
Wherein, the LTE antenna emits signal within the same period with WLAN antennas there may be a side and the opposing party connects
The situation of the collection of letters number, it is also possible to exist while emit signal or receive the situation of signal simultaneously.Wherein, if the LTE antenna
Exist between WLAN antennas and mutual interference coexists, if there are side transmitting signals within the same period when LTE antenna and WLAN antennas
And the opposing party receives the situation of signal, for example LTE antenna is in transmitting signal condition, WLAN antennas are in receiving state signal,
Influencing for the LTE signals for the successive bands that the WLAN signal that then WLAN antennas receive can be emitted by LTE antenna, then perform step
Rapid 103.
If when LTE antenna emits signal within the same period or receives signal simultaneously simultaneously with WLAN antennas, two days
Line will not be interfered with each other in sequence at work, can perform step 104.
Step 103, the signal modulation mode of the WLAN antennas is adjusted to the second modulation system from the first modulation system.
The effective bandwidth of wherein described second modulation system is less than the effective bandwidth of first modulation system.
WLAN usually supports multiple standards pattern, such as 802.11b/g/n.Different mode standards is operated in, is modulated
Also difference, the occupied bandwidth of different adjustment modes are also different for mode.For example, by taking table 1 as an example, 802.11b can be adopted
With the modulation system of CCK, either the modulation system of OFDM may be used in 802.11g or 802.11n to 802.11a.For example, same
In one electronic equipment, while support the mode standards such as 802.11b/g/n.
Table 1
For example, under 20MHz protocol bandwidth operating conditions, 802.11b uses the modulation system of CCK, having during work
Effect bandwidth is typically less than 14MHz.Under 20MHz protocol bandwidth operating conditions, 802.11g/n uses OFDM modulation systems, work
Effective bandwidth when making is typically larger than 16MH.The effective bandwidth of CCK modulation systems is less than the effective bandwidth of OFDM modulation systems
Therefore, can modulation system be changed by mode standard when changing WLAN work, to influence work letter
Number effective bandwidth, and then influence to fall spurious signal size in adjacent frequency section.
If when LTE antenna and WLAN antennas, there are the feelings that a side emits signal and the opposing party's reception signal within the same period
The signal modulation mode of the WLAN antennas then can be adjusted to the second modulation system, wherein institute by shape from the first modulation system
The effective bandwidth for stating the second modulation system is less than the effective bandwidth of first modulation system.For example, second modulation system
Can be the CCK modulation systems under 802.11b mode standards, first modulation system can be 802.11g/n mode standards
Under OFDM modulation systems, the effective bandwidth of CCK modulation systems is less than the effective bandwidth of OFDM modulation systems.
According to the working strategies of current WLAN data network and LTE mobile data networks, the field of mutual interference occurs for WLAN and LTE
Jing You：(1) LTE mobile data networks use data traffic, and WLAN data network is not connected with wireless network access point AP but is holding
Row active scan；(2) LTE mobile data networks are in call scene, and WLAN data network connection on wireless network access point
Net performs active scan.
WLAN data network can emit the signal of CCK modulation systems, WLAN data when performing and scan by WLAN antennas
For network when being connected to wireless network access AP online, WLAN antennas may be the signal in transmitting CCK modulation systems, it is also possible to
It is the signal in transmitting OFDM modulation systems.Under general communication strategy, particularly LTE mobile data networks are being in call field
Jing Shi, such as when answering the call or making a phone call, the normal priority of LTE mobile data networks is higher than WLAN data network.Therefore exist
In the embodiment of the present application, when mutual interference coexists in WLAN antennas and LTE antenna, if the working signal of WLAN antennas using
OFDM modulation systems then need to adjust operating mode to 802.11b, i.e., using the modulation system of CCK.

In some embodiments, it if there is no mutual interference coexists between LTE antenna and WLAN antennas, is held according to original strategy
Row, the signal modulation mode of the WLAN antennas is remained unchanged.
In some embodiments, if there is no side transmitting signals within the same period with WLAN antennas for the LTE antenna
And the opposing party receives the situation of signal, then according to original strategy execution, the signal modulation mode of the WLAN antennas is maintained not
Become.
In some embodiments, it is adjusted in the signal modulation mode by the WLAN antennas from the first modulation system
Before second modulation system, further include：
Judge whether the frequency range interval between the working frequency range of the LTE signals and the working frequency range of the WLAN signal is small
In predetermined interval；
If the frequency range interval between the working frequency range of the LTE signals and the working frequency range of the WLAN signal is less than default
Interval, then be adjusted to the second modulation system by the signal modulation mode of the WLAN antennas from the first modulation system.
In some embodiments, it whether there is one within the same period with WLAN antennas in the detection LTE antenna
After side's transmitting signal and the opposing party receive the situation of signal, further include：
If the LTE antenna emits signal there is no a side within the same period with WLAN antennas and the opposing party receives signal
Situation, then the signal modulation mode of the WLAN antennas is remained unchanged.
In some embodiments, it is adjusted in the signal modulation mode by the WLAN antennas from the first modulation system
After second modulation system, further include：
Obtain the signal quality of the WLAN signal of the WLAN antenna transmissions；
If the signal quality of the WLAN signal is less than second threshold, the working channel of the WLAN signal is adjusted to
The channel of LTE signal working frequency range far from LTE antenna transmission.
The alternative embodiment that any combination forms the present invention may be used, herein no longer in above-mentioned all optional technical solutions
It repeats one by one.
Referring to Fig. 3, the another flow that mutual interference processing method coexists for a kind of antenna provided by the embodiments of the present application by Fig. 3 is shown
It is intended to.The method includes：
Step 201, judge between LTE antenna and WLAN antennas with the presence or absence of mutual interference coexists, wherein the LTE antenna with
The position of WLAN antennas is adjacent.If so, perform step 202；If it is not, then perform step 207.
Wherein, step 201 sees step 101, and details are not described herein.
Step 202, the LTE antenna and WLAN antennas are detected and emits signal and another with the presence or absence of a side within the same period
One side receives the situation of signal.If so, perform step 203；If it is not, then perform step 207.
Wherein, the LTE antenna emits signal within the same period with WLAN antennas there may be a side and the opposing party connects
The situation of the collection of letters number, it is also possible to exist while emit signal or receive the situation of signal simultaneously.Wherein, if the LTE antenna
Exist between WLAN antennas and mutual interference coexists, if there are side transmitting signals within the same period when LTE antenna and WLAN antennas
And the opposing party receives the situation of signal, for example LTE antenna is in transmitting signal condition, WLAN antennas are in receiving state signal,
Influencing for the LTE signals for the successive bands that the WLAN signal that then WLAN antennas receive can be emitted by LTE antenna, then perform step
Rapid 203.
If when LTE antenna emits signal within the same period or receives signal simultaneously simultaneously with WLAN antennas, two days
Line will not be interfered with each other in sequence at work, can perform step 207.
Step 203, judge between the frequency range between the working frequency range of the LTE signals and the working frequency range of the WLAN signal
Every whether less than predetermined interval.If so, perform step 204；If it is not, then perform step 207.
Wherein, if the LTE antenna emits signal there are a side within the same period with WLAN antennas and the opposing party receives
The situation of signal, such as LTE antenna are in transmitting signal condition, and WLAN antennas are in receiving state signal, then in two signals
When mutual interference coexists in appearance, the size at the frequency range interval of the working frequency range between two signals is with falling the spurious signal size in adjacent frequency section
It is inversely proportional, the frequency range interval of the working frequency range between two signals is smaller, and the spurious signal fallen in adjacent frequency section is bigger.In WLAN antennas
When mutual interference occurs with LTE antenna, WLAN antennas use OFDM modulation systems, obtain the work that WLAN antennas use OFDM modulation systems
Make the frequency range interval between frequency range and the current working frequency range of LTE, so with obtain occur between WLAN antennas and LTE antenna it is mutual
The maximum frequency interval can be set as the predetermined interval by maximum frequency interval when disturbing.During electronic device works, if
It detects that the frequency range interval of WLAN antennas and the working frequency range of LTE antenna is less than the predetermined interval, illustrates to fall in adjacent frequency section
Spurious signal is larger, and interference is stronger, then needs to perform step 204.If detect the frequency of WLAN antennas and the working frequency range of LTE antenna
It is intersegmental that every not less than the predetermined interval, illustrating to fall, the spurious signal in adjacent frequency section is smaller, and interference is smaller, then can perform step
207。
Step 204, the signal modulation mode of the WLAN antennas is adjusted to the second modulation system from the first modulation system.
During electronic device works, if detect WLAN antennas and the working frequency range of LTE antenna frequency range interval be less than it is described
The operating mode of WLAN antennas is then adjusted to 802.11b (CCK) by predetermined interval, i.e., by the signal modulation of the WLAN antennas
Mode is adjusted to CCK modulation systems from OFDM modulation systems.

Wherein, by the signal modulation mode of the WLAN antennas from the first modulation system be adjusted to the second modulation system it
Afterwards, although reducing effective bandwidth of operation of signal, and then the mutual interference influence between LTE and WLAN, WLAN antennas are reduced
Working frequency range between LTE antenna is still successive bands, and WLAN antennas are it is also possible to there are the low situation of transmission performance, then
Need further to obtain the signal quality of the WLAN signal of the WLAN antenna transmissions, to determine the transmission performance of WLAN antennas
It is good and bad.Such as Signal to Interference plus Noise Ratio SINR (the Signal to Interference plus of detection WLAN antennas
Noise Ratio), Reference Signal Received Power RSRP (Reference Signal Receiving Power), receive signal
Intensity indicates the parameters such as RSSI (Received Signal Strength Indication) to judge the letter of acquisition WLAN antennas
Number quality.
Step 206, if the signal quality of the WLAN signal is less than second threshold, the work of the WLAN signal is believed
Road is adjusted away from the channel of the LTE signal working frequency range of the LTE antenna transmission.
Wherein, for example, the signal quality of the WLAN signal is represented with received signal strength indicator RSSI, such as described
Two threshold values are set as -95dBm, if the RSSI of the WLAN signal is -102dBm, illustrate the signal matter of the WLAN signal
Amount cannot maintain normal signal transmission less than second threshold, the current working channel of the WLAN antennas, then by described in
The working channel of WLAN signal is adjusted away from the channel of the LTE signals working frequency range.For example, the work that the WLAN antennas are current
Make channel as channel 1 (centre frequency 2412MHz), the working channel of LTE signals is B40 (working frequency range 2300-
2400MHz), if the signal quality of the WLAN signal is less than second threshold, by the working channel of the WLAN signal from letter
Road 1 is adjusted to the channel 11 (centre frequency 2462MHz) far from the LTE signals working frequency range, so that WLAN signal
Working frequency range of the working frequency range as possible far from LTE signals, increases isolation between antennae with this.
Step 207, the signal modulation mode of the WLAN antennas is remained unchanged.
In some embodiments, it if there is no mutual interference coexists between LTE antenna and WLAN antennas, is held according to original strategy
Row, the signal modulation mode of the WLAN antennas is remained unchanged.
In some embodiments, if there is no side transmitting signals within the same period with WLAN antennas for the LTE antenna
And the opposing party receives the situation of signal, then according to original strategy execution, the signal modulation mode of the WLAN antennas is maintained not
Become.
