Continue.As shown in Fig. 2 methods described may include steps of：
Step 21, obtains the actual emission power value of signal when emitter launches nth data bag, and n is
Positive integer.
In wireless communications, the data for being carried in signal are transmitted in the form of packet, each signal

On step 23 and 24, in specific implementation, the gain of transmission signal and the working condition of emitter
Correlation, and the working condition of emitter is related to the situation of change that it is loaded, the change feelings of transmitter load
Condition is different, and the gain of signal is also just different when determining that the emitter launches (n+1)th packet.Therefore,
When it is determined that the emitter launches (n+1)th packet during the gain of signal, can first according to the ratio
Relatively result, it is determined that launch (n+1)th packet when emitter working condition, further according to the hair
The working condition of machine emitter when (n+1)th packet is launched is penetrated, the emitter transmitting (n+1)th is determined
The gain of signal during individual packet, finally according to identified gain to emitter transmitting described (n+1)th

The working condition of the emitter is divided into：First state sta0 and the second state sta1.Wherein, described
Whether one state sta0 is to change the state for being detected to the transmitter load, the second state sta1
It is the state of power blockage after transmitter load change.
Specifically, by setting first threshold th1 and Second Threshold th2, to the working condition of emitter
Divided, wherein, th1 ＜ th2.Work shape when the emitter launches the nth data bag
When state is first state, if during err ＜ th1, i.e., the actual hair of signal when emitter launches nth data bag
Power and objective emission difference power are penetrated away from smaller, the emitter is in when (n+1)th packet is launched
Second state sta1, otherwise remains first state sta0.When the emitter launches the nth data
When working condition during bag is the second state, if during err >=th2, emitter transmitting nth data Bao Shixin
Number actual emission power and objective emission difference power away from larger, the emitter is launching the (n+1)th number
First state sta0 is in during according to bag, the second state sta1 is otherwise remained.
In the working condition according to emitter emitter when (n+1)th packet is launched, institute is determined
When stating the gain of signal when emitter launches (n+1)th packet, if the emitter is in transmitting (n+1)th
Working condition during individual packet is identical with working condition when launching nth data bag, then directly by institute
The gain of signal is launching the (n+1)th number as the emitter when stating emitter transmitting nth data bag
The gain of signal during according to bag.
If working condition of the emitter when (n+1)th packet is launched and transmitting nth data bag
When working condition it is different, on the one hand can first obtain when the emitter launches (n+1)th packet and believe
Number transmission power level P1 to be calibratedn+1, according to P1n+1From default transmission power mapping table Table-2
Obtain corresponding gain pointer Base_idxn+1；On the other hand, can be calculated to the according to the value of err
The calibration parameter Δ PPC that n+1 packet is calibratedn+1, wherein, Δ PPCn+1=err+ Δs PPCn.Finally
To Base_idxn+1And Δ PPCn+1Summation, obtains calibration pointer；According to calibration pointer from default gain
The target gain pointer of signal when launching (n+1)th packet is obtained in pointer maps table Table-3
indexn+1, and according to indexn+1Corresponding gain is obtained from default gain map table Table-4, i.e.,：
Table-4 (n+1)=Table-3 (indexn+1)=Table-3 (Base_idxn+1+ΔPPCn+1)=Table-3
(Base_idxn+1+err+ΔPPCn)。
In another embodiment of the invention, as shown in figure 4, removing first state sta0 and the second state sta1
Outward, the working condition of the emitter can be with：Third state sta2.Wherein, the third state sta2
It is after the transmitter power losing lock, first state sta0 or the second state sta1 to be in the emitter
The state for being confirmed.
Specifically, the working condition when the emitter launches the nth data bag is first state
During sta0, if err ＜ th1, i.e. emitter transmitting nth data bag when signal actual emission power and mesh
Mark transmission power gap is smaller, and the emitter is in the second state when (n+1)th packet is launched
Sta1, otherwise remains first state sta0.Work when the emitter launches the nth data bag
When making state for the second state sta1, if during err ＞ th3, signal during emitter transmitting nth data bag
Actual emission power and objective emission difference power away from excessive, the emitter is launching (n+1)th data
Third state sta2 is in during bag, the second state sta1 is otherwise remained.When emitter transmitting described the
When working condition during n packet is third state sta2, if err >=th2, emitter is launched n-th
Away from larger, the emitter is in transmitting for the actual emission power of signal and objective emission difference power during packet
First state sta0 is in during (n+1)th packet, is otherwise the second state sta1.Wherein, th1 ＜ th3
＜ th2.
It is understood that when whether the specific working condition for judging emitter shifts, th1, th2 and th3
Itself it is a boundary value, state transfer can be carried out when err is equal to corresponding preset value, it is also possible to small
State transfer is carried out when corresponding preset value.In other words, in the work of emitter described in boundary value
Whether making state can shift, it is also possible to not shift, specifically shift, and can voluntarily be set by technical staff.
Whether however, performing transfer, such scheme is within the scope of the present invention.
In the working condition according to emitter emitter when (n+1)th packet is launched, institute is determined
When stating the gain of signal when emitter launches (n+1)th packet, if the emitter is in transmitting (n+1)th
Working condition during individual packet is identical with working condition when launching nth data bag, then directly by institute
The gain of signal is launching the (n+1)th number as the emitter when stating emitter transmitting nth data bag
The gain of signal during according to bag.
