Specific implementation mode
In the prior art, the physical port of the DSLAM in xDSL systems and the physical port of CPE pass through multiple twisted-pair feeders pair Connection, wherein multiple twisted-pair feeder can also be to be held together to that can be the multiple twisted-pair feeders pair being arranged in same cable Multiple twisted-pair feeders.Following application documents are with the physical port of the physical port of DSLAM and CPE by including 4 twisted-pair feeders pair Cable connection for illustrate.
The physical port of DSLAM include 4 logic ports, it is assumed that 4 logic ports be respectively TXP1, TXP2, TXP3, TXP4.For the inside DSLAM, each logic port corresponds to an xTU-Os in DSLAM, for the cable being connect with DSLAM, Each logic port corresponds to a twisted-pair feeder pair of cable.Correspondingly, the physical port of CPE includes 4 logic ports, it is assumed that should 4 logic ports are respectively RXP1, RXP2, RXP3, RXP4.For the inside CPE, each logic port corresponds to one in CPE XTU-Rs, for the cable being connect with CPE, each logic port corresponds to a twisted-pair feeder pair of cable.In this way, make The each xTU-Rs being located on CPE is obtained to connect with an xTU-Os on DSLAM by a twisted-pair feeder pair.
The corresponding channel transfer matrices H of the corresponding channel transfer matrices H and CPE of DSLAM for example can be such as following formula (1) It is shown：
Wherein, hijIndicate twisted-pair feeder to j to twisted-pair feeder to the transmission equation of i.I, j is positive integer, and is less than or equal to 4.When hijIn j with i differences when, the hijIndicate twisted-pair feeder j twisted-pair feeder the far-end cross talk caused by i.
According to the H-channel transmission matrix it is found that DSLAM and CPE is when by network cable transmission signal, each of cable is double Twisted wire can cause far-end cross talk to other twisted-pair feeders to the signal transmitted to the signal transmitted.Therefore, in order to ensure institute The quality of the signal of transmission, DSLAM and CPE can pass through multiple-input and multiple-output (Multiple-Input Multiple- Output, MIMO) technology eliminates the far-end cross talk, so that h different with i j in above-mentioned H-matrixijIt is 0.Wherein, it uses The DSL system that MIMO technology eliminates far-end cross talk can be referred to as mimo system.
By taking sender, recipient as an example, how DSLAM and CPE are carried out to eliminate the far-end cross talk by MIMO technology Explanation.Wherein, sender can be DSLAM, recipient CPE, alternatively, sender is CPE, recipient DSLAM.
Transmission signal sequence x is expressed as to one 4 × 1 channel input vector.That is, the transmission signal sequence packet Include 4 subsequences, wherein each subsequence can be that the logic port of sender is sent to the signal of recipient.This 4 Subsequence in sending signal sequence put in order with sender send the subsequence logic port put in order it is identical. Receive the channel output vector that signal sequence y is expressed as one 4 × 1.That is, the reception signal sequence includes 4 sub- sequences Row, wherein each subsequence can be the signal received by the logic port of recipient, which is receiving In signal sequence put in order with recipient receive the subsequence logic port put in order it is identical.N is one 4 × 1 noise vector.Then the transmission equation between sender and recipient can be as shown in following formula (2)：
Y=Hx+n (2)
Sender can introduce a pre-coding matrix P, so that sender when sending signal sequence, can believe sending After number sequence x carries out precoding processing, by the transmission signal sequence after precodingIt is sent to channel up.It shouldIt can adopt It is indicated with following formula (3)：
Recipient can introduce a crosstalk cancellation matrix W, so that recipient is when receiving signal sequence, it can be to receiving Coded treatment after signal sequence y is carried out, the reception signal sequence after being encoded after obtainingIt shouldFollowing formula (4) table may be used Show：
Above-mentioned formula (3) is substituted into above-mentioned formula (2), then above-mentioned formula (2) is substituted into formula (4), then above-mentioned (4) into Following formula (5) expression may be used in one step：
In order to make other h in matrix H in addition to diagonal lineijIt is 0, that is to say, that in order to make in above-mentioned H-matrix H different with i jijIt is 0.Above-mentioned matrix W and P can be that progress to channel transfer matrices H certain decomposed form is (such as unusual Value is decomposed etc.) after obtained matrix so that after WHP is multiplied, the h that keeps j different with iijIt is 0, to eliminate twisted-pair feeder to j Twisted-pair feeder caused by i far-end cross talk, ensure the transmission quality of signal.
Since matrix P used in above-mentioned sender is that sender decomposes obtained matrix according to channel transfer matrices H, Matrix W and P used in recipient are that recipient decomposes obtained matrix according to channel transfer matrices H.Therefore, in order to It is correctly received signal, sender and recipient need to use same channel transfer matrices H when handling signal.
Currently, sender can determine transmission square according to the line sequence for the twisted-pair feeder pair being connect with its 4 logic ports Battle array H, correspondingly, recipient can determine channel transfer matrices according to the line sequence for the twisted-pair feeder pair being connect with its 4 logic ports H.When the cable for connecting the physical port of physical port and recipient of sender is straight-through network cables, that is, it is located at the cable both ends 4 twisted-pair feeders pair line sequence it is identical, that is to say, that inside the cable, 4 twisted-pair feeders are not to intersecting.At this point, this 4 Used line sequence when 4 logic ports of a twisted-pair feeder to connecting sender, with 4 twisted-pair feeders to connecting the 4 of recipient Used line sequence is identical when a logic port.

At this point, sender's identified channel under the line sequence of 4 twisted-pair feeders pair of the cable being connect with its physical port Transmission matrix H, and, recipient's identified channel under the line sequence of 4 twisted-pair feeders pair of the cable being connect with its physical port Transmission matrix H is identical, which can be indicated with following formula (6)：
When the cable for connecting the physical port of physical port and recipient of sender is crossover network cables, that is, it is located at the net The line sequence of 4 twisted-pair feeders pair at line both ends is different, that is to say, that inside the cable, which intersects to producing. At this point, used line sequence when 4 logic ports of 4 twisted-pair feeders to connecting sender, connects with 4 twisted-pair feeders to connecting Used line sequence is different when 4 logic ports of debit.

In view of the above situation, the processing method of intersection line sequence provided herein, it is intended to which solving MIMO technology can not The technical issues of suitable for using DSLAM and CPE for intersecting line sequence connection.
The technical solution of the application is described in detail with specifically embodiment below.These specific implementations below Example can be combined with each other, and same or analogous concept or process may be repeated no more in some embodiments.
Fig. 3 is a kind of flow diagram of processing method for intersecting line sequence provided by the present application.As shown in figure 3, this method May include：
S101, the first equipment obtain the mapping of multiple logic ports of the first equipment and multiple logic ports of the second equipment Relationship.
Specifically, in the present embodiment, above-mentioned first equipment and the second equipment can be the equipment in mimo system.Its In, the physical port of the first equipment is connect by cable with the physical port of the second equipment, the physical port of the first equipment and The physical port of two equipment includes multiple logic ports, and cable includes multiple twisted-pair feeders pair corresponding with multiple logic interfacings, Multiple twisted-pair feeders are to multiple logic ports using the first line sequence the first equipment of connection, and multiple twisted-pair feeders using the second line sequence to being connected Connect multiple logic ports of the second equipment.When specific implementation, when the first equipment can be above-mentioned described DSLAM, at this point, second Equipment can be above-mentioned described CPE.Alternatively, the first equipment can be above-mentioned described CPE, at this point, the second equipment can be Above-mentioned described DSLAM.
According to aforementioned exemplary description it is found that when the cable for connecting the first equipment and the second equipment is crossover network cables, first The mapping relations of multiple logic ports of equipment and multiple logic ports of the second equipment, with, connection the first equipment and second set When standby cable is straight-through network cables, the mapping relations of multiple logic ports of the first equipment and multiple logic ports of the second equipment It is different.Therefore, in the present embodiment, the first equipment can first obtain the mapping relations, so that the first equipment can pass through The mapping relations judge whether the cable of the first equipment of connection and the second equipment is crossover network cables, i.e. multiple twisted-pair feeders pair of cable Whether the first line sequence and the second line sequence of the second equipment of connection for connecting the first equipment are different.
Wherein, the present embodiment does not limit the mode that above-mentioned first equipment obtains above-mentioned mapping relations.Optionally, the first equipment The signal that can be sent in each logic port according to the second equipment determines the multiple logic ports and the second equipment of the first equipment Multiple logic ports mapping relations.The above-mentioned mapping relations that first equipment can also be sent by receiving the second equipment, come Obtain the mapping relations etc..
S102, the first equipment determine whether the first line sequence intersects with the second line sequence according to mapping relations.
Specifically, the first equipment is in the multiple logic ports for getting the first equipment and multiple logic ports of the second equipment Mapping relations after, the first equipment can be known by the mapping relations, and each logic port of the first equipment passes through its company The twisted-pair feeder pair connect, it is corresponding with which logic port of the second equipment, so that the first equipment is each patrolled according to the first equipment Collect the logic port of corresponding second equipment in port, it may be determined that First Line of the multiple twisted-pair feeders of cable to the first equipment of connection Whether sequence and the second line sequence of the second equipment of connection are different.
By taking the first equipment is above-mentioned DSLAM, the second equipment is above-mentioned CPE as an example, if the mapping relations that DSLAM is got For：The RXP1 of TXP1 and CPE of DSLAM is corresponding, and the RXP2 of TXP2 and CPE of DSLAM is corresponding, the TXP3's and CPE of DSLAM RXP3 is corresponded to, and the RXP4 of TXP4 and CPE of DSLAM is corresponding.At this point, the twisted-pair feeder in the cable for passing through connection DSLAM and CPE, So that the sequence of each logic port of DSLAM in dslam, and, CPE's corresponding with the logic port of DSLAM patrols It is identical to collect the sequence of port in the cpe.Illustrate multiple twisted-pair feeders in cable to connecting the first line sequence of the first equipment and connecting Second line sequence of the second equipment is identical, that is, the first line sequence and the second line sequence are not intersected.
If the mapping relations that DSLAM is got are：The RXP3 of TXP1 and CPE of DSLAM is corresponding, the TXP2 and CPE of DSLAM RXP2 correspond to, the RXP1 of TXP3 and CPE of DSLAM is corresponding, and the RXP4 of TXP4 and CPE of DSLAM is corresponding.At this point, passing through company Connect the twisted-pair feeder in the cable of DSLAM and CPE so that the sequences of the logic port TXP1 of DSLAM in dslam, and, with The sequences of the logic port RXP3 of the corresponding CPE of DSLAM logic ports TXP1 in the cpe are different.The logic port TXP3 of DSLAM Sequence in dslam, and, the sequence of the logic port RXP1 of CPE corresponding with DSLAM logic ports TXP3 in the cpe It is different.Illustrate multiple twisted-pair feeders in cable to connecting the first line sequence of the first equipment and connecting the second line sequence of the second equipment not Together, that is, the first line sequence and the second line sequence have intersection.
It is to be passed that S103, the first equipment adjust the first equipment when the first line sequence is intersected with the second line sequence, according to the second line sequence The position of subsequence in the first defeated signal sequence, obtains second signal sequence.
If specifically, according to foregoing description it is found that intersect since the first line sequence and the second line sequence exist, if at this point, first By the synchronous transmission training sequence signal of the line sequence intersected between equipment and the second equipment, then the first equipment is received by Training sequence signal and the second equipment received by training sequence signal it is different so that the first equipment and the second equipment Channel transfer matrices H accessed by different training sequence signals is different.In this way, the first equipment and the second equipment are in base When different channel transfer matrices H handles signal sequence to be transmitted so that make in the first equipment and the second equipment Will be unable to correctly get reception signal sequence for the equipment of recipient, cause the first equipment and the second equipment can not normally into Row communication so that MIMO technology can not be suitable for intersecting the first equipment and the second equipment of line sequence connection.
Therefore, in the present embodiment, the first equipment is determining that the first line sequence and the second line sequence have friendship according to mapping relations When fork, the position of the subsequence in the first equipment the first signal sequence to be transmitted can be adjusted according to the second line sequence, to To second signal sequence.In the second signal sequence each subsequence put in order for：Conduct in first equipment and the second equipment Multiple logic ports of the equipment of recipient signal received under the second line sequence puts in order.Wherein, above-mentioned described Each subsequence in first signal sequence can be：Each of equipment in first equipment and the second equipment as sender is patrolled Collect the signal that port is sent.
Optionally, if the first equipment is sender, the second equipment is recipient.Then the first equipment can be according to the second line Sequence is adjusted to according to tactic first signal sequence of multiple logic ports of the first equipment according to the more of the second equipment A tactic second signal sequence of logic port.Optionally, if the first equipment is recipient, the second equipment is sender, Then the first equipment can be according to the second line sequence, will be according to multiple logic ports of the first equipment tactic to be transmitted first Signal sequence is adjusted to the tactic second signal sequence of multiple logic ports according to the second equipment.In this way, in the first He When equipment and the second equipment transmit the second signal sequence, which passes through the cable that there is intersection line sequence and passes to After the equipment of recipient so that the cable that there is intersection line sequence can intersect second signal sequence again, so that The signal sequence received by the equipment as recipient is obtained, it is identical as the first signal sequence to be transmitted.When specific implementation, It can be adjusted according to the first signal sequence of mapping relations pair by the second equipment, can specifically be set according to the first equipment and second Standby negotiation result determines, is repeated no more to this.
If at this point, the first signal sequence to be transmitted be training sequence signal, such as：Orthogonal sequence or pseudo- orthogonal guide frequency sequence It arranges, then the first equipment and the mode of the second equipment through this embodiment so that recipient is used as in the first equipment and the second equipment Equipment can obtain training sequence signal identical with the first signal sequence transmitted by sender so that the first equipment It is based on the identical training sequence signal with the second equipment, obtains identical channel transfer matrices H.
Optionally, if the first equipment is sender, the second equipment is recipient, then the first equipment is according to the first signal sequence Obtained channel transfer matrices H, the obtained signal sequence of second signal sequence sent according to the first equipment with the second equipment It is identical as the first signal sequence, so that the second equipment is set based on the channel transfer matrices H that the signal sequence obtains with first Standby obtained channel transfer matrices H is identical.Optionally, if the first equipment is recipient, the second equipment is sender, then first The channel transfer matrices H that equipment is obtained according to second signal sequence, with the first equipment according to the signal sequence for being sent to the first equipment Arrange that obtained signal sequence is identical as second signal sequence, so that the channel that the second equipment is obtained based on the signal sequence Transmission matrix H is identical as the obtained channel transfer matrices H of the first equipment.
In this way, the first equipment and the second equipment can be negotiated, so that one subsequently in transmitting business signal sequence with both sides Side can be adjusted signal sequence to be transmitted according to mapping relations, so that the signal sequence after adjustment is by first After recipient in equipment and the second equipment receives, obtained signal sequence and the signal sequence phase transmitted by sender Together, and two signal sequences are matched with the first equipment and the used channel transfer matrices H of the second equipment.In this way, first sets Standby and the second equipment can be based on identical channel transfer matrices H to letter to be transmitted in transmitting business signal sequence process Number sequence is handled, and is connect so that can correctly be got as the equipment of recipient in the first equipment and the second equipment Receive signal sequence so that MIMO technology can be adapted for the first equipment and the second equipment of intersecting line sequence connection.Wherein, it first sets How standby and the second equipment is based on training sequence signal, obtains channel transfer matrices H, may refer to the prior art, no longer to this It repeats.
Illustratively, by taking the first equipment is above-mentioned DSLAM, the second equipment is above-mentioned CPE as an example, wherein DSLAM is to send Side, CPE is recipient.First signal sequence to be transmitted is { S1, S2, S3, S4 }, multiple logic ports of DSLAM and CPE's The mapping relations of multiple logic ports are：The RXP3 of TXP1 and CPE of DSLAM is corresponding, RXP2 pairs of the TXP2 and CPE of DSLAM It answers, the RXP1 of TXP3 and CPE of DSLAM is corresponding, and the RXP4 of TXP4 and CPE of DSLAM is corresponding.
Then DSLAM, can be according to the second line sequence, by the first signal sequence when determining that the first line sequence is intersected with the second line sequence In the sequence of subsequence be adjusted, the position of S1 and the S3 transmitted by TXP3 that script is transmitted by TXP1 are replaced, Second signal sequence is obtained, i.e. { S3, S2, S1, S4 }.In this way, the second signal sequence is being passed through 4 logic ports by DSLAM When being sent to CPE, i.e., S3 is sent to the RXP3 of CPE by TXP1, S2 is sent to the RXP2 of CPE by TXP2, is passed through S1 is sent to the RXP1 of CPE by TXP3, S4 is sent to the RXP4 of CPE by TXP4, i.e., by the line sequence of the intersection to signal After being intersected again, so that the signal sequence received by CPE is { S1, S2, S3, S4 }, with the first signal sequence phase Together.
By this adjustment, the signal sequence that the first signal sequence and CPE of DSLAM transmissions receive is identical, if at this point, The signal sequence is training sequence signal, then DSLAM is based on the channel transfer matrices H accessed by the first signal sequence, with, CPE is identical according to the channel transfer matrices H that the signal sequence received is got.In this way, DSLAM and CPE are based on identical When channel transfer matrices H handles signal sequence to be transmitted so that CPE, which can correctly be got, receives signal sequence Row so that MIMO technology can be adapted for the DSLAM and CPE that intersect line sequence connection.It should be noted that, although this example with DSLAM is sender, and CPE is the explanation carried out for recipient, it will be appreciated by those skilled in the art that When DSLAM is recipient, CPE is sender, it is equally applicable to this example, the technique effect reached is identical.
The processing method provided by the present application for intersecting line sequence is used in the first equipment and the second equipment with intersection line sequence When multiple twisted pair line connections, the first equipment can be according to multiple twisted-pair feeders pair that multiple logic ports with the second equipment are connect Line sequence relationship adjusts the position of the subsequence in the first signal sequence to be transmitted, obtains second signal sequence, so that the One equipment and the second equipment can be based on which, training sequence signal be sent, so that in the first equipment and the second equipment The first signal sequence that equipment as sender is sent, and, the signal sequence that the equipment as recipient receives is identical, into And so that sender and recipient are based on the identical signal sequence, identified channel transfer matrices H is identical, solves MIMO skills Art can not be suitable for the technical issues of using the first equipment and the second equipment for intersecting line sequence connection.
