Point, to limit length of the maximum length of stroke as target packet.
Step 102: obtaining the phase of the data bit in previous the first data packet being transmitted of target packet.
Wherein, the first data packet refers to the last data packet being transmitted before target packet, such as institute in Fig. 3
Show, data packet A and data packet B have been transmitted before target packet, before data packet B, data packet B is data packet A
The data packet being just transmitted, and sorting after data packet B is that target packet preparation starts to transmit, and is obtained in the present embodiment

So that circuit stability is worked, and do not need to increase additional extra order during this realization, is to have in the data of transmission
It data imitated, and then not will cause the loss of data transmission efficiency, thus achieve the purpose that 100% data transmission efficiency.
In one implementation, after obtaining target packet in a step 101 in the present embodiment, can also include with
Lower step, as shown in Figure 4:
Step 105: judge data bit in target packet phase whether be full low level or overall height position phase, if mesh
The phase of data bit is not the phase of full low level or overall height position in mark data packet, then without executing step 102 and step 103,
Phase Processing is not carried out to target packet, target packet can directly be transmitted, data will not be caused to transmit
The extension of stroke length, the and if phase of data bit is the phase of full low level or overall height position in target packet, can be with
Step 102 and subsequent step are continued to execute, front and back data packet is carried out by differentiated with this, on the basis of limiting stroke length

According to efficiency of transmission, and if the phase of data bit is different from the phase of data bit in the first data packet in target packet,
It just no longer needs to execute step 103, Phase Processing is not carried out to target packet, target packet can directly be transmitted,
The extension for the stroke length that data will not be caused to transmit.
In one implementation, step 103 can be accomplished by the following way in specific implementation, as shown in Figure 5:
Step 501: if the phase of data bit and the phase of data bit in the first data packet are complete in target packet
The phase of low level or overall height position, then the phase to data bit in target packet carries out phasing back.
Wherein, the phasing back in the present embodiment refers to, is the phase of overall height position by the phasing back of full low level, or will
The phasing back of overall height position is the phase of full low level.
Step 502: the target packet Jing Guo phasing back being handled, so that target packet has target special

His D1 and D5-D6 is still the high position relative to reference line originally, so that target packet has multilevel phase；
In the case that data bit is full low level in target packet, at least partly data bit in target packet
Phase carries out reduction processing, in Fig. 7, reduces to the phase of the data bit of D3-D4 in target packet, and other D1-
D2 and D5-D6 is still original low level, so that target packet has multilevel phase.
It should be noted that the multilevel phase in the present embodiment is not limited to two-stage phase, it is also even more comprising three-level
The phase setting of grade.
As it can be seen that by the way that multilevel phase multi- is arranged to data bit in the target packet after phasing back in the present embodiment

It should be noted that the specific implementation of each structure of receiver can be with reference to hereinbefore corresponding in the present embodiment
Content and attached drawing, and will not be described here in detail.
Below to transmitting number between TX transmitter (transmitter) and RX receiver (receiver) in the present embodiment
It is illustrated according to the specific implementation of data (data packet):
Firstly, judging in the present embodiment each data packet (T) being sequentially transmitted, if transmission data (N-2)
A T (transmission times of the data of stroke length) is random data (non-all high and non-all low), can be without
Data-signal is passed to Rx from Tx by any processing.
It is the data of all high or all low if transmission data (N-1) a T and (N-2) T is different,
Data signal can also be passed to Rx from Tx without any processing.
If the data of (N) a T transmission is the random data or phase reverse phase of the opposite phase of (N-1) T data
All high or all low data of position, can also be without any processing.
But if data continuously transmits same phase data within the time of (N-1) T and two 2T of (N) T, and this 2 T
Data will lead to run-length (throwing into question to ce circuit characteristic), need to carry out at reversion when transmitting (N) T data at this time
It is transmitted after reason plus multi-level.
As shown in Figure 15, case1-case4 is respectively the normal of (N-2) a T, (N-1) a T and (N) a T
Data transmit when Phase Processing schematic diagram, wherein the data of (N-2) a T be non-full 0 and non-complete 1, (N-1) a T's
Data is full 0 (case1 and case3), and it is initial data, proposed that the data of (N) a T, which is complete 1, normal data,
Data is the data that Phase Processing is crossed, it can be seen that, the signal and all high data or all of multi-level transmission
The data of low data same phase, transmission data will not go out problem of dtmf distortion DTMF, will not lose the transmission efficiency of data.In order to examine
Multi-level out can add 2 contrast circuits for examining multi-level, level in the present embodiment in the receiver
Detection is run under the relatively low frequency of 1/N, consumes electric current and size increases meeting very little.
As shown in Figure 16, in the side Tx, initialization (initialization) process terminates after powering on Power on
Afterwards, the data transmission of Tx to Rx is ready.If (N) is a, (N+1) T is all high or all low, (N+
1) data of a T transmission need to invert, and increase multi-level signal after the data of (N) a T and transmit together.Same side
The data of formula supplement confirmation (N+2) T, determines that the data finally exported is transmitted after confirming 3 packet information altogether.
Shown in original Tx_org and Tx_out in case1 and case2 as shown in Figure 17.Case1 (example 1) is continuous 3T
The transmission example of Tx_out when transmitting identical data in the time, case2 is the identical data of transmission in the continuous 2T time, in the 1T time
The transmission example of Tx_out when transmission reversion data.REF+, REF- are two voltage of level in checking R x
Reference signal.
Correspondingly, as shown in Figure 18, being opened after powering on Power on and initialization initialization in the side Rx
Begin to receive data, if received data has multi-level signal, to all high or all low of corresponding T
Data carries out reversion processing, i.e., resilient original data.
As it can be seen that in circuit, run-length hold time it is longer will lead to ce circuit characteristic issues, be holding circuit
Stablize need limit maximum run-length scheme.All it can increase extra order on original bit number in traditional scheme
Overhead bit, such transmission efficiency can reduce.The multi-level scheme mentioned in the present embodiment does not have additional
RX can be allowed to receive accurate data signal in the increased situation of bit.The case where continuously transmitting same phase there are two the above T
Under reversion transmission carried out to second T data limit run-length.Because by reversion processing transmission signal message with
The information of transmission is initially wanted on the contrary, the information that RX is received is wrong.So being inverted in the present embodiment to second T
Multi-level processing is carried out while processing, and RX is made to learn that this is reversion when receiving the processed information of multi-level
Information afterwards, then inverted, receive data same as initially transmission data.
It should be noted that the multi-level that the application mentions not only can be adapted for data-signal all high or
In the case where person all low, can be used under any any mode (pattern) for influencing circuit stability work with
Upper multi-level scheme handles the data-signal in circuit, to realize corresponding purpose.
