Description
【Technical field】
The invention belongs to the communication technologys, are related to a kind of data carrier identity method.
【Background technology】
In wireless data transmission network, co-channel interference, more antennas, which often occur, cannot cooperate situation, existing
In wireless communication system, the signal that wireless receiver receives is a unknown combination signal, this combination signal is wirelessly connecing
The initial time for coming from which transmitter, not knowing radiofrequency signal, existing wireless receiver are not known before the demodulation of receipts machine
It is the demodulation ability that receiver is reacted by signal-to-noise ratio parameter, that is to say, that the demodulation of the lower wireless receiver of signal-to-noise ratio is more tired
Difficulty, particularly homogenous frequency signal, which interfere with each other, can make wireless receiver that can not demodulate effective information.
【Invention content】
To solve the deficiencies in the prior art, it the object of the present invention is to provide a kind of data carrier identity method, is penetrating
Frequency input phase is known that the identity and initial time for receiving radiofrequency signal, and the interference processing for radiofrequency signal provides condition.
To solve the above-mentioned problems, the present invention adopts the following technical scheme that：
Data carrier identity method, includes the following steps：
Step 1: selection subcarrier；
Step 2: wireless data communication carrier wave identity information is carried on subcarrier；
Step 3: subcarrier is sent to receiving terminal before data communication carrier；
Step 4: immediately following subcarrier transmission data communication carrier.
Further, the step 2 subcarrier chooses orthogonal frequency, and carrying information；
Further, wireless data communication carrier wave identity information includes data transmission carrier receiving device id information and data pass
Defeated carrier wave sending device id information.
Further, subcarrier is demodulator or carrier wave detection unit, is sent for detecting transmitter with subcarrier
Identity information.
Further, identity information is carried on subcarrier using subcarrier system.
The data carrier identity method of the present invention, using subcarrier system banner data carrier identity, makes to connect
Receipts machine has been known that whether signal is oneself useful signal when data carrier radiofrequency signal reaches, in this way can be by specified
Algorithm solve wireless data communication with frequency, simultaneously, duplex transmission, multiple antennas collaboration, it is wireless anti-interference the problems such as.
Subcarrier carries the receiving device id information that data transmission carrier is sent to and data transmission carrier sends out and sets
Standby id information, the identity and initial time for receiving radiofrequency signal are known that in radio frequency input phase, are at the interference of radiofrequency signal
Offer condition is provided.
【Description of the drawings】
Fig. 1 is the workflow block diagram of the embodiment of the present invention 1
【Specific embodiment】
Provide present pre-ferred embodiments below in conjunction with the accompanying drawings, with the technical solution that the present invention will be described in detail, but not because
This is limited the present invention among the embodiment described range.
The data carrier identity method of the present invention, includes the following steps：
Step 1: selection subcarrier；
Step 2: wireless data communication carrier wave identity information is carried on subcarrier；
Step 3: subcarrier is sent to receiving terminal before data communication carrier；
Step 4: immediately following subcarrier transmission data communication carrier.
It will be appreciated by those skilled in the art that subcarrier can be detected by orthogonal manner, they can with carrying information,
It will be obvious to a person skilled in the art that wireless communication networks have reserved many carrier frequency points for compatibility, such as 4G networks in order to which compatibility is set
3G, 2G detection frequency point are reserved in standby, we can use 2G, 3G frequency point as subcarrier.
It will be appreciated by those skilled in the art that it can be used for detaching same frequency carrier wave after carrier wave identity.
One subcarrier can choose orthogonal frequency, and carrying information；
Secondly subcarrier bearer data transmission carrier wave receiving device id information；
Thirdly subcarrier bearer data transmission carrier wave sending device id information.
Embodiment 1：
As shown in Figure 1, the data carrier identity method flow of the present embodiment is as follows：
S101a, selection subcarrier scheme；
S102a, carrier wave identity information is edited on subcarrier, including sending device id information, receiving device id information；
S103a, setting subcarrier and data carrier transmission time interval；
S104a, subcarrier is sent；
S105a, transmission data carrier wave；
S106a, end of identification is sent.
Data carrier identity method of the present invention identifies the identity of a data transmission carrier with one group of subcarrier,
Designation date carrier wave receiving device, sending device information, it be solve wireless data communication with frequency, simultaneously, duplex transmission, more days
Line cooperates with, it is wireless anti-interference the problems such as key technology, one carrier wave identity used one group of subcarrier；Secondly auxiliary
Carrier identification data carrier sending device ID, receiving device id information.
Such as multiple antennas association processing：Wireless signal is in external space propagation because of transmission range, signal reflex, scattering etc.
Factor, the time for reaching different antennae is different, and when having radio frequency identity marking and time identifier, we can be incited somebody to action by delayer
All antenna radio-frequency signal phase adjustments pass through the enhancing that arithmetic unit realizes signal to consistent.
Such as co-channel interference is eliminated：For homogenous frequency signal, it is contemplated that the amplitude of data carrier is held with phase in data communication
Data information is carried, amplitude and Phase Continuation in ordinary circumstance carrier wave duration, carrier wave duration, carrier frequency are
Know parameter, then we are received by subcarrier identity recognizing technology and subcarrier time identifier technology in very short time
To noiseless radiofrequency signal, its amplitude and phase are calculated, it is possible to extrapolate the amplitude and phase of interference signal, pass through algorithm
Eliminate interference.
Complete specific statement is carried out to the technical solution in the present invention herein, still, example described herein is only
It is a part of example, is not whole examples.On the basis of the present invention, those skilled in the art are not making innovative work
Other examples obtained under the premise of work belong to the scope that the present invention protects.
