The Relation acquisition of amount impedance value corresponding with difference, obtains the first impedance value.Wherein, the first impedance value is also possible to the control of terminal
Make what organic above-mentioned steps obtained.
Based on previous embodiment, the embodiment of the present invention provides a kind of Poewr control method, as shown in figure 4, above-mentioned be based on
Two adjustment information adjust the second signal to be processed power, obtain the method for the second output signal the following steps are included:
Step 106a, terminal is according to first control signal, by the way that the corresponding impedance value of the second signal to be processed is subtracted
One impedance value obtains the second output signal to reduce the power of the second signal to be processed.

Impedance value.In this way, the reverse impedance variable due to impedance-tumed system tunes system worked well, so terminal is by by second
First impedance value of the corresponding impedance value reduction of signal to be processed obtains to realize that the power to the second signal to be processed reduces
To the second output signal.
Based on previous embodiment, the embodiment of the present invention provides a kind of Poewr control method, as shown in figure 5, the present invention is implemented
For example when to be mainly used in preset threshold be second threshold, difference is less than the application scenarios of second threshold, then it is above-mentioned according to difference with
Preset threshold, obtain second adjustment information method the following steps are included:
If step 103c, difference is less than second threshold, terminal generates second control signal.
Wherein, preset threshold is second threshold, and less than zero, second control signal is used to indicate terminal and increases the second threshold
The power of two signals to be processed.

It is connected to impedance variable tuning system, increase processing is carried out to the corresponding impedance value of the second signal to be processed to realize.Meanwhile eventually
Third resistance value is also sent to forward impedance variable tuning system by the controller at end, to inform that forward impedance variable tuning system has
The impedance value that body need to increase be the second impedance value, in this way, by increase second processing signal impedance value come realize by second to
The power for handling signal increases, and obtains the second output signal.
In this way, terminal executes step 103a-103b and step 106a or step 103c-103d and step 106b, due to the
The power of two signals to be processed is very close to predetermined power, if continuing through the mode of adjust gain to the second signal to be processed
Power be adjusted, then be not easily adjusted as predetermined power value, thus can by way of adjusting impedance value to second to
The power of processing signal is finely adjusted, and the power of the second signal to be processed is rapidly accurately adjusted to predetermined power by realization,
Improve the adjusting efficiency for adjusting the output signal power of terminal.
Based on previous embodiment, the embodiment of the present invention provides a kind of Poewr control method, obtains the side of the first adjustment information

State the method that the first adjustment information is obtained according to difference and preset threshold the following steps are included:
If step 104a, difference is greater than first threshold, terminal generates third and controls signal.
Wherein, preset threshold is first threshold, and first threshold is greater than zero, and third control signal is used to indicate terminal reduction and puts
The gain of big first signal power to be processed.
Specifically, since first threshold is greater than zero, so the power of the first output signal is greater than predetermined power, in order to reduce
The power of terminal output signal, terminal generate the control letter for being used to indicate the gain of adjustment the first signal power to be processed of amplification
Number, i.e. the controller of terminal, which can be generated, is used to indicate the of the gain that terminal reduces the first signal power to be processed of current amplification
Three control signals, and third control signal is sent to power amplifier.
Step 104b, terminal obtains the first gain corresponding with difference according to the relationship of difference and gain variables.
Wherein, the first adjustment information includes that the first gain and third control signal.
Specifically, difference and the relationship of gain variables can be and pre- first pass through many experiments acquisition and need to adjust different outputs letters
When difference number between power and predetermined power, what is obtained need to be adjusted the gain of the first signal to be processed of amplification
The relationship of gain variables, difference and gain variables can be the list about difference and gain variables, can be stored in advance in end
In end.The relationship of difference and gain variables is also possible to based on the calculation formula between power and gain, in this way, using the power
The difference of calculation formula between gain, power and predetermined power to the first output signal calculates, and obtains corresponding
Yield value is realized as the first gain.
For example, the controller of terminal is using calculation formula between power and gain, to the first power and predetermined power it
Between difference calculated, obtain yield value corresponding with the difference, be the first gain, and the first gain be sent to power and is put
Big device.
Based on previous embodiment, the embodiment of the present invention provides a kind of Poewr control method, as shown in figure 8, above-mentioned be based on
One adjustment information adjust the first signal to be processed power, obtain the method for the second signal to be processed the following steps are included:
Step 105a, terminal controls signal according to third, and the corresponding gain of the first signal to be processed is reduced the first gain,
Obtain the second gain.
Specifically, the corresponding gain of the first signal to be processed can be fixedly installed in terminal for be processed to first
The gain that the power of signal amplifies.For example, the power amplifier of terminal controls signal according to the third received, to power
The gain of amplifier setting carries out turning processing down, specifically turns the first gain down, obtains the second gain.
Step 105b, terminal amplifies the power of the first signal to be processed based on the second gain, obtains the second signal to be processed.
Specifically, due to the second gain be less than last time the power of the first signal to be processed is amplified it is first to be processed
The corresponding gain of signal obtains the second letter to be processed so terminal amplifies the power of the first signal to be processed based on the second gain
Number, for the power for amplifying the first signal to be processed based on the gain of the first signal to be processed compared to last time at this time, obtain the
The power of two signals to be processed has reduced.It should be noted that terminal amplifies the power of the first signal to be processed based on the second gain
Afterwards, the second gain can be set to the corresponding gain of the first signal to be processed, but in application scenes, terminal is based on the
After the power of the first signal to be processed is amplified in two gains, restoring gain is the corresponding gain of the first signal to be processed.
