In link.
Balun is power diversity device of the single-ended signal to double-end signal.Balun has three ports, including an input,
Two differential ends (i.e. the first differential ends and the second differential ends), input and differential ends impedance value may be unequal, but two differences
Divide terminal impedance value equal, realize input and output impedance mapping function.Balun simulates letter in communication of mobile terminal link
Number Interference Suppression System framework, forms transmission signal S after modulates baseband signals to radio frequency domains carrier waveIN, by balun linear transformation
Power diversity, is divided into that amplitude is equal, the first transmission signal S of opposite in phaseOUT1With the second transmission signal SOUT2, formula is as follows：
Wherein, the first transmission signal SOUT1With the second transmission signal SOUT2Amplitude is allFirst transmission signal SOUT1It is logical
Cross the transmitting antenna and be transmitted into space, the second transmission signal SOUT2Entered into receives link with after reception Signal averaging, by
It is in phase differenceThe time overhead of regulation phase is eliminated, convergence signal speed is accelerated.
Alternatively, Fig. 3 will be connect in the step of a kind of signal processing method according to an exemplary embodiment includes
The collection of letters number is input into a flow chart for receives link with secondary signal, as shown in figure 3, the second differential ends of the balun are connected to decay
Device, is provided with the combiner for being connected to the attenuator in the receives link.The reception letter that the reception antenna is received
It is input into receives link after number being superimposed with the secondary signal, is comprised the following steps.
In step S231, the secondary signal is input into the attenuator, so that the secondary signal is according to target
Attenuation ratio is decayed.
In step S232, by decay after the secondary signal and combiner described in the reception signal input in.
As the transmission signal SINIt is divided into the first transmission signal S by balunOUT1With the second transmission signal SOUT2Afterwards, first
Transmission signal SOUT1Receive to form self-interference signal by reception antenna again after the transmitting antenna is transmitted into space, this mistake
Journey can decay, therefore, the second transmission signal S offseted with self-interference signalOUT2Need to be by attenuator, according to target
Attenuation ratio decays into signal Scancel, ScancelThe the first transmission signal S received with reception antennaOUT1Belong on frequency spectrum same
Frequency band signals, the two can be offseted after being superimposed in combiner, you can to eliminate self-interference signal.

In step S43, the target attenuation ratio is determined.
In step S44, the secondary signal is input into the attenuator, so that the secondary signal declines according to target
Subtract ratio decay.
In step S45, by decay after the secondary signal and combiner described in the reception signal input in.
In order to determine the target attenuation ratio, as shown in figure 5, described determine the target attenuation ratio, including it is following
Step.
In step S431, the attenuator is controlled to decay successively the secondary signal with M different attenuation ratio.
In step S432, the M secondary signal after being decayed with differential declines ratio sequentially inputs the combining
In device, so that the reception signal and the M secondary signal export M output signal after being sequentially overlapped.
In step S433, the M output signal is converted into corresponding DC voltage numerical signal.
In step S434, the minimum target DC voltage numerical signal of DC voltage numerical value, the target direct current are obtained

In, M=2N.Such as, the attenuator has six toggle switch to control different attenuation degrees, then have 26, that is, have 64
Different attenuation ratios.
For example, as the transmission signal SINIt is divided into the first transmission signal S by balunOUT1With the second transmission signal
SOUT2Afterwards, the first transmission signal SOUT1Space, the second transmission signal S are transmitted into by transmitting antennaOUT2By after attenuator, pressing
Decay into different signal S according to different attenuation ratioscancel, different ScancelThe first transmitting for being received with reception antenna successively
Signal SOUT1After being superimposed in the combiner, can be for transmission to wave detector in, to realize that signal power is changed into different direct currents
Pressure numerical signal Svoltage, the different DC voltage numerical signal S that processor can be gatheredvoltageStore.Assuming that decay
When device has six toggle switch, processor can be by the toggle switch control signal S of 6 bit digitals ' 0 ', ' 1 ' of outputDijitalCome
Six break-makes of toggle switch of regulated attenuator, with control respectively different weight (0.5dB, 1dB, 2dB, 4dB, 8dB,
16dB) realize different attenuation ratios, processor control toggle switch is realized from 000000~111,111 2 totally6Secondary different groups
Close traversal one time, different d. c. voltage signal S are corresponded to respectivelyvoltage, then processor is from 26Individual different d. c. voltage signal
SvoltageIn, select the toggle switch control signal S corresponding to the numerical value of minimumDijital, now corresponding toggle switch control
Signal SDijitalBe exactly the target attenuation ratio of attenuator, i.e., the toggle switch control signal S corresponding to minimum numerical valueDijital
It is exactly the optimum value of control elimination communication link analog domain self-interference signal.
The disclosure travels through regulation process to determine the target attenuation ratio of attenuator by digital self-adapting, and then according to
The target attenuation ratio is decayed secondary signal, then by decay after the secondary signal and receive signal input combiner,
So as to eliminate self-interference signal, Communication System Design complexity and time complexity are reduced, reduce interference signal elimination algorithm
Time overhead, for eliminate mobile terminal noise jamming a kind of signal quick regulation scheme is provided.
