Description
Technical field
The present invention relates to technical field of micro communication, more particularly to a kind of application CCDP (Co-Channel Dual
Polarized, single channel dual polarization) and XPIC (Cross-Polarisation Interference
Counteracter, cross polarization interference canceler) microwave transmission when the method and device that avoids interference.
Background technology
Microwave communication is widely used now as a kind of means of communication, due to increasing sharply for business and bandwidth,
Frequency resource seems more and more wellr sold and in short supply, and one can be applied using the polarization interference cancellation techniques of CCDP and XPIC
The frequency two-way business simultaneous transmission different to polarised direction avoids interfering, and improves the service efficiency of frequency.
CCDP refers to use horizontal polarized wave and vertically polarized wave transmitting two paths of signals in a channel.CCDP
2 tunnels be orthogonal signalling with frequency microwave signal, because two paths of signals is transmitted using perpendicular mode,
So will not disturb therebetween.
XPIC is cross polarization interference canceler, is a kind of technology for coordinating CCDP to use.CCDP utilizes two-way
Between orthogonal polarized wave transmission signal realizes that transmission capacity is doubled, and XPIC is then used for eliminating two-way polarized wave
Cross jamming.Ideally, 2 of CCDP are orthogonal signalling with frequency microwave signal, therebetween will not
Disturb, but under the conditions of Practical Project, regardless of two orthogonalities of signal, always to receive antenna
XPD (Cross Polarization Discrimination rate, cross polarization discrimination) and channel are passed
The influence of defeated deterioration, it is impossible to which interference between the signals is deposited in the meeting for avoiding.In order to offset these interference, it is necessary to
Use XPIC technologies.The general principle of XPIC technologies is to receive signal from horizontal and vertical two polarised directions,
And the two is carried out into certain treatment so as to recover primary signal from disturbed signal.
Overall procedure the Modem Horizontal and Modem of CCDP and XPIC as can be seen from Figure 1
Vertical sends the two-way business that two-way is designated thick lines and hachure respectively, and two-way business passes through CCDP
Transmitted using orthogonal two paths of signals, opposite end receive be isolated by filtration out after the two paths of signals of doping interference it is dry
Disturb and recover original two-way business with after another road signal cancellation after signal.
When the method for application CCDP+XPIC is transmitted, if the veneer of business breaks down because of weather all the way
Reason receives signal and is deteriorated and leads to not receive and can be led in the case of providing offseting signal without another road of normal direction
Cause all disabled situation of two-way business.

Transmitting element on off state：Transmitting element opens or closes state where business.
Second step (continues always for a period of time when the detection module of transmission unit detects the lasting losing lock of the road business
It is out-of-lock condition, transmission unit thinks current business failure) after, the radio-frequency module of correspondence transmission unit is closed,
And start Timed Recovery according to the time that time series produces into algorithm generation.
Time series generating algorithm unit is the second：
T (1)=10
T (n+1)=T (n) * (n+2) (n=1,2,3,4)
T (n)=T (n-1) (n>=6)
3rd step when being timed to after attempt opening the radio-frequency module t of transmission unit, and signal companion transmission unit
The out-of-lock detection time is adjusted into 2t, and (it is always out-of-lock condition to continue 2t, and transmission unit thinks current business event
Barrier), if then rear partner's transmission unit is lock-out state to t, failure business recovery successfully removes timer,
If if t then after partner's transmission unit be out-of-lock condition failure business recovery fail, closing radio-frequency module,
Waited according to time series restarting timing and attempt next time recovering.
Radio-frequency module is opened after transmission unit detects locking.
That is, be two transmission units by the different two-way business configuration of polarised direction, when H (V) is passed
The transmission unit that defeated unit detects H when current business breaks down (V) direction can be automatically switched off radio-frequency module,
The normal work in its interference V (H) direction is prevented, after H (V) transmission unit closes radio-frequency module, can be according to
The time series of special algorithm generation opens radio-frequency module and attempts recovering, if business recovery success Flow ends,
Future time point is waited to continue to attempt to recover until business recovery success if recovering unsuccessfully closing radio-frequency module.
Implementation of 4 to the accompanying drawing 6 to technical scheme below in conjunction with the accompanying drawings is described in further detail：

State is losing lock；
2nd, losing lock closes radio-frequency module after reaching 2S.
That is, transmission unit detect this transmission unit current business whether losing lock, when detecting this biography
, it is necessary to close the radio frequency unit of this transmission unit during the current business losing lock of defeated unit.
Fig. 5 is provided in an embodiment of the present invention according to time series trial recovery flow chart, as shown in figure 5,
Start the time startup generated according to time series generating algorithm in recovery process and recover timer, timer is then
The service transmitting unit of transmission unit is opened afterwards, starts timer, timing length t, and signal companion transmission is single
Unit's startup is anti-tampering, and (partner's transmission unit does not turn off transmission list after detecting traffic failure within a certain period of time
Unit).Check whether current business is health status after when t is timed to, if business is health status, failure
Business recovery success, Flow ends, if service condition is unhealthy, are generated next according to time generating algorithm
Time starts timer and continues to attempt to recover, until the success of failure business recovery.
Fig. 6 be it is provided in an embodiment of the present invention detect business recovery health treatment flow chart, as shown in fig. 6,
Business recovery health treatment flow is detected during business recovery, when business recovery health is detected, is checked
Whether it is closed mode that current business sends, if business is sent as open mode, and handling process does not terminate, if
Current business is closed mode, the service transmitting unit of opening transmission unit, startup timer, timing length t,
And signal companion transmission unit startup 2t is anti-tampering, and (partner's transmission unit detects business event within a certain period of time
Transmitting element is not turned off after barrier).Check whether current business is health status after when t is timed to, if industry
It is health status to be engaged in, the success of failure business recovery, and Flow ends, if business is unhealthy condition, close hair
Send unit, Flow ends.
Foregoing duration t can be set according to system situation in the range of 2~5s.
In sum, the present invention has following technique effect：
Present invention application CCDP with XPIC when being transmitted when business all the way in the different two-way business of polarised direction
