It should be noted that transmission power measurement and control system shown in Fig. 1 is only described in the embodiment of the present invention
One of calibration method application example, the calibration method there may also be other implementations, those skilled in the art can root
According to actual needs, system referring to fig. 1 is implemented.
Below with reference to Fig. 2, describe in detail to the calibration method of transmission power described in the embodiment of the present invention.Such as Fig. 2
Shown, the method may include following steps:
Step 21, the actual emission power value of signal when obtaining transmitter transmitting nth data packet, n is positive integer.
In wireless communications, the data carried in signal are transmitted in the form of data packet, and each signal may include
Multiple data packets, the actual emission power value of signal may be identical when emitting different data packets, it is also possible to different.In the present invention
Embodiment in, the nth data packet can be a signal nth data packet, can also with two or more letter
Number data packet carry out it is accumulative after nth data packet.
It should be noted that in an embodiment of the present invention, the transmitter be can by signal according to certain frequency into
The device of row transmitting, can be applied in the wireless telecom equipments such as TV, broadcast, mobile unit, user terminal.Also, it is described
The communication pattern of wireless telecom equipment can be LTE mode, WLAN (Wireless Local Area Network,
WLAN) mode, global mobile communication (Global System For Mobile, GSM) mode, TD SDMA
(Time Division-Synchronous Code Division Multiple Access, TD-SCDMA) mode, code point are more
Location (Code Division Multiple Access, CDMA) 2000 modes etc..
Step 22, by the actual emission power value of signal when emitting the nth data packet and the transmitting nth data
The objective emission performance number of signal is compared when packet.
In specific implementation, the objective emission performance number of signal can deposit in advance when the transmitter transmitting different data packet
Storage is in target power table Table-1.The target power table Table-1 is the objective emission performance number by detection data packet
What the corresponding relationship between actual emission power value obtained.The target power value information of different data packet is stored in Table-1,
And with the one-to-one actual emission power value information of target power value.Emit nth data when getting the transmitter
The actual emission power value P1 of signal when packetnAfterwards, corresponding objective emission power is obtained from the target power table Table-1
Value P2n, and by the P1nWith P2nIt is compared.Enable err=P1n-P2n, err is comparison result.
Step 23, the gain of signal when determining that the transmitter emits (n+1)th data packet according to comparison result.
Step 24, signal to school when emitting (n+1)th data packet to the transmitter according to identified gain
Quasi- transmission power level is calibrated.
About step 23 and 24, in specific implementation, the gain for emitting signal is related to the working condition of transmitter, and sends out
The working condition for penetrating machine is related to the situation of change that it is loaded, and the situation of change of transmitter load is different, determines the transmitter
The gain of signal is also just different when emitting (n+1)th data packet.Therefore, (n+1)th data packet of the transmitter transmitting is being determined
When signal gain when, can determine the work of transmitter when emitting (n+1)th data packet first according to the comparison result
State determines the transmitter transmitting further according to the working condition of transmitter transmitter when emitting (n+1)th data packet
The gain of signal when (n+1)th data packet finally emits (n+1)th data to the transmitter according to identified gain
The transmission power level to be calibrated of signal is calibrated when packet.
In one embodiment of this invention, as shown in figure 3, according to the situation of change of transmitter load, by the transmitter
Working condition be divided into: first state sta0 and the second state sta1.Wherein, the first state sta0 is to the transmitter
Whether load changes the state detected, and the second state sta1 is the shape of power blockage after transmitter load variation
State.
Specifically, by setting first threshold th1 and second threshold th2, to be divided to the working condition of transmitter,
Wherein, th1 < th2.When working condition when the transmitter emits the nth data packet is first state, if err <
When th1, i.e., transmitter transmitting nth data packet when signal actual emission power and objective emission difference power away from smaller, it is described
Transmitter is in the second state sta1 when emitting (n+1)th data packet, otherwise remains first state sta0.When the transmitting
When working condition when machine emits the nth data packet is the second state, if transmitter emits nth when err >=th2
According to the actual emission power and objective emission difference power of signal when packet away from larger, the transmitter is in (n+1)th data packet of transmitting
When be in first state sta0, otherwise remain the second state sta1.
In the working condition according to transmitter transmitter when emitting (n+1)th data packet, the transmitter is determined
When emitting (n+1)th data packet when the gain of signal, if working condition of the transmitter when emitting (n+1)th data packet with
Working condition when emitting nth data packet is identical, then the gain of signal when the transmitter directly being emitted nth data packet
Gain as transmitter signal when emitting (n+1)th data packet.
If work when working condition of the transmitter when emitting (n+1)th data packet and transmitting nth data packet
State is different, on the one hand can first obtain the transmission power level to be calibrated of signal when the transmitter emits (n+1)th data packet
P1n+1, according to P1n+1Corresponding gain pointer Base_idx is obtained from preset transmission power mapping table Table-2n+1；It is another
Aspect can calculate the calibration parameter Δ PPC calibrated to (n+1)th data packet according to the value of errn+1, wherein Δ
PPCn+1=err+ Δ PPCn.Finally to Base_idxn+1And Δ PPCn+1Summation obtains calibration pointer；According to calibration pointer from pre-
If gain pointer maps table Table-3 in obtain emit (n+1)th data packet when signal target gain pointer
indexn+1, and according to indexn+1Corresponding gain is obtained from preset gain map table Table-4, it may be assumed that
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, described as shown in figure 4, in addition to first state sta0 and the second state sta1
The working condition of transmitter can be with: third state sta2.Wherein, the third state sta2 is to lose in the transmitter power
After lock, the state that first state sta0 or the second state sta1 are confirmed is in the transmitter.
Specifically, when the working condition when the transmitter emits the nth data packet is first state sta0, if
