Example one
Referring to fig. 1, a flowchart illustrating steps of a signal control method according to a first embodiment of the present invention is shown.
The signal control method of the embodiment of the invention comprises the following steps:
step 101: under the condition that a first radio frequency module and a second radio frequency module of the electronic device are simultaneously started, a first radio frequency band and first radio frequency transmitting power of a first radio frequency signal transmitted by the first radio frequency module are obtained.
The first radio frequency module and the second radio frequency module may be radio frequency modules corresponding to existing radio frequency bands, for example, the first radio frequency module may be an LTE module, and the second radio frequency module may be a GPS module. In an actual use process, under the condition that the first radio frequency module and the second radio frequency module are simultaneously started, a first radio frequency signal transmitted by the first radio frequency module interferes with a second radio frequency signal transmitted and received by the second radio frequency module.
Suppose that: the signal strength of the first radio frequency signal allowed by the second radio frequency module to enter the second radio frequency module is AdBm; the first radio frequency transmitting power of a first radio frequency signal transmitted by a first radio frequency module is BdBm; the isolation between the first radio frequency module and the second radio frequency module is CdB; the suppression degree of the first radio frequency signal sent by the first radio frequency module on the second radio frequency module path is DdB; if it is to be ensured that the first RF signal does not interfere with the second RF signal, B-C-D is smaller than A. In the embodiment of the invention, the filter switch in the second radio frequency module is controlled to control the first radio frequency signal entering the second radio frequency module, so that the effect of dynamically adjusting the isolation degree on the second radio frequency module channel is achieved, and finally, the influence of the first radio frequency signal on the positioning accuracy of the second radio frequency module is reduced under the condition of not sacrificing the quality of the first radio frequency signal.
Step 102: a first antenna standing wave of a first radio frequency module and a second antenna standing wave of a second radio frequency module are obtained.
The electronic equipment is provided with a standing wave detection circuit, and a first antenna standing wave and a second antenna standing wave of the electronic equipment in the current state are obtained through the standing wave detection circuit.
Step 103: and controlling the switch of a filter in the second radio frequency module according to the acquired first radio frequency band, the acquired first radio frequency transmitting power, the acquired first antenna standing wave and the acquired second antenna standing wave.
The filter is used for adjusting the first radio frequency signal in the second radio frequency module.
The values of A, B, C and D in the above example are determined by the acquired first rf frequency band, the first rf transmitting power, the first antenna standing wave, and the second antenna standing wave, and whether to turn on the filter in the second rf module is determined according to the values of the parameters.
In the signal control method provided by the embodiment of the present invention, under the condition that a first radio frequency module and a second radio frequency module of an electronic device are simultaneously turned on, a first radio frequency band and a first radio frequency transmission power of a first radio frequency signal transmitted by the first radio frequency module are obtained, and a first antenna standing wave of the first radio frequency module and a second antenna standing wave of the second radio frequency module are obtained; according to the first radio frequency band, the first radio frequency transmitting power, the first antenna standing wave and the second antenna standing wave, the first radio frequency signal entering the second radio frequency module is adjusted by controlling the switch of the filter in the second radio frequency module, the interference of the first radio frequency signal transmitted by the first radio frequency module on the second radio frequency signal transmitted and received by the second radio frequency module can be effectively reduced without reducing the first radio frequency power of the first radio frequency signal, and the effect of a communication network can be prevented from being influenced.
Example two
Referring to fig. 2, a flowchart illustrating steps of a signal control method according to a second embodiment of the present invention is shown.
The signal control method of the embodiment of the invention is applied to electronic equipment, and comprises the following steps:
step 201: under the condition that a first radio frequency module and a second radio frequency module of the electronic device are simultaneously started, a first radio frequency band and first radio frequency transmitting power of a first radio frequency signal transmitted by the first radio frequency module are obtained.
In the embodiment of the present invention, the first radio frequency module is an LTE module, and the second radio frequency module is a GPS module. The LTE module provides communication service, the GPS module provides positioning service, and the first radio frequency signal is generated by the LTE module. Under the condition that an LTE module and a GPS module of the electronic equipment are simultaneously started, the first radio frequency signal can cause interference on the GPS signal, namely the second radio frequency signal, and the positioning accuracy of the GPS module is influenced. The control signal method in the embodiment of the invention can effectively reduce the interference of the first radio frequency signal to the GPS signal.
Wherein the first rf transmit power may be represented by symbol B.
Step 202: a first antenna standing wave of a first radio frequency module and a second antenna standing wave of a second radio frequency module are obtained.
The electronic equipment is provided with a standing wave detection circuit, and a first antenna standing wave and a second antenna standing wave of the electronic equipment in the current state are obtained through the standing wave detection circuit. The specific arrangement of the standing wave detection circuit may refer to the related art, which is not particularly limited in the embodiment of the present invention.
Step 203: and determining isolation degree information corresponding to the first radio frequency band, the first antenna standing wave and the second antenna standing wave according to a preset relation table.
The electronic device stores a preset relation table, and the preset relation table comprises corresponding relations of the signal control related parameters under different first radio frequency bands. The corresponding relationship of the relevant parameters in each first radio frequency band is specifically as follows: the isolation degree corresponding to the first antenna standing wave and the second antenna standing wave under the first radio frequency band; the maximum signal intensity of the first radio frequency signal which can be received by the second radio frequency module under the first radio frequency band, and the inhibition degree of the first radio frequency signal by the second radio frequency module. The isolation degree corresponding to the first antenna standing wave and the second antenna standing wave can be represented by symbol C.
Antenna standing wave and isolation information in a preset relation table are tested in a laboratory; under different antenna standing wave states, the isolation degree between the first antenna standing wave and the second antenna standing wave is different. The maximum strength of the first radio frequency signal allowed to enter the second radio frequency module under the first radio frequency band can be obtained through a chip specification of a specific scheme, and the suppression degree of the second radio frequency module on the first radio frequency signal can be obtained through testing by a network analyzer. The relevant parameters in the relation table are determined in the above way and then are added in the preset relation table in advance.
Step 204: and determining a first signal strength and a first suppression degree corresponding to the first radio frequency band according to a preset relation table.
The first signal strength is the maximum signal strength of the second radio frequency module capable of receiving the first radio frequency signal, and the first suppression degree is the suppression degree of the second radio frequency module on the first radio frequency signal. The maximum signal strength of the first rf signal allowed to enter the second rf module can be represented by symbol a, and the suppression level can be represented by symbol D.
Step 205: and controlling the switch of a filter in the second radio frequency module according to the first radio frequency transmitting power, the first isolation degree, the first signal strength and the first suppression degree.
The filter is used for adjusting the first radio frequency signal in the second radio frequency module.
A preferred switching manner for controlling the filter in the second rf module according to the first rf transmitting power, the first isolation, the first signal strength and the first suppression degree is as follows:
firstly, determining a first difference value between a first radio frequency transmitting power and a first isolation degree;
secondly, determining a second difference value between the first difference value and the first inhibition degree;
and thirdly, determining the working state of the switch of the filter according to the second difference and the first signal strength.
Specifically, under the condition that the second difference value is greater than the first signal strength, a switch of the filter is closed, and the working frequency band of the filter is set to be a first radio frequency band; in the case where the second difference is less than or equal to the first signal strength, the switch of the filter is kept in an open state.
That is, by comparing B-C-D (the signal strength of the actual first radio frequency signal entering the second radio frequency module) with a, if B-C-D > a, the switch of the filter is closed, and the working frequency band of the filter is set to the first radio frequency band of the acquired first radio frequency signal; if B-C-D < ═ A, the switch of the filter is kept in the open state.
In the signal control method provided by the embodiment of the present invention, under the condition that a first radio frequency module and a second radio frequency module of an electronic device are simultaneously turned on, a first radio frequency band and a first radio frequency transmission power of a first radio frequency signal transmitted by the first radio frequency module are obtained, and a first antenna standing wave of the first radio frequency module and a second antenna standing wave of the second radio frequency module are obtained; according to the first radio frequency band, the first radio frequency transmitting power, the first antenna standing wave and the second antenna standing wave, the first radio frequency signal entering the second radio frequency module is adjusted by controlling the switch of the filter in the second radio frequency module, the interference of the first radio frequency signal transmitted by the first radio frequency module on the second radio frequency signal transmitted and received by the second radio frequency module can be effectively reduced without reducing the first radio frequency power of the first radio frequency signal, and the effect of a communication network can be prevented from being influenced.
