Embodiment 1
The embodiment of the present invention provides a kind of signal output method, application and mobile terminal, and as shown in Figure 1, the method can comprise:
101, the power that obtains the first signal of the power amplifier module output of described mobile terminal, obtains the first power.
Wherein, described first signal is to need by the signal of the antenna transmission of mobile terminal after power amplifier module amplifies.In interference field, due to a part of power disturbed source reflection in first signal that exists of interference source, can not launch, the part signal being reflected is secondary signal.
102, obtain the power of the secondary signal being reflected in described first signal, obtain the second power.
In the present embodiment, obtain the first power and obtain the second power and there is no sequencing, after can first obtaining the first power, obtain the second power, or obtain the first power after first obtaining the second power, can also obtain described the first power and the second power, the embodiment of the present invention does not limit this simultaneously.

104, export described first signal according to described matching scheme.
Wherein, according to matching scheme selected in step 103, set the relevant electric capacity of output and/inductance, export described first signal.Because selected matching scheme is the reflection standard that meets reasonable transmitting output signal, or the part that in optional alternative, signal is reflected is minimum, therefore can improve the efficiency that signal is launched, and need not improve constantly power output.
The signal output method that the embodiment of the present invention provides, by obtaining the power of the secondary signal being reflected in the power of first signal of power amplifier module output of described mobile terminal and described first signal, determine the matching scheme of the described first signal of output, only can carry compared with high-power technology according to the instruction of base station with mobile terminal in prior art, the situation that can be reflected according to the first signal of output, adjust the matching scheme of output signal, reduce the ratio that signal is reflected, thereby without the power output that improves simply first signal, can reduce the electromagnetic radiation causing of mobile terminal, and reduce the power consumption of mobile terminal.
The embodiment of the present invention provides a kind of signal output method, application and mobile terminal, and as shown in Figure 2, the method can comprise:
201, pre-configured at least two group alternatives.
