Description
Technical field
The present invention relates to network communication technology field, more particularly to a kind of ultrashort wave radio set Hopping frequencies distribution method.
Background technology
The wavelength of ultrashort wave radio set is 1-10 meters, and its working frequency is located between 30M -300M, in recent years, ultrashort wave electricity
Platform is widely used in civilian and tactical environment, and a large amount of due to ultrashort wave radio set use, and its frequency available resources is limited how
It is a large amount of while the ultrashort wave radio set subnet dividing frequency of work is also an important research class in effective frequency range
Topic.
It is contemplated that a kind of distribution method of ultrashort wave radio set Hopping frequencies is provided, for solving the big rule of ultrashort wave radio set
Frequency interference issue during module net, improves the efficiency of ultrashort wave radio set communication.
The content of the invention
With the large-scale application of ultrashort wave radio set, how each radio station subnet is given by limited frequency resource allocation, it is ensured that
Each radio station subnet normal work in the case where not interfereing with each other, as industry pain spot.
The present invention devises a set of frequency allocation method worked well to solve the problem.To make the elaboration of the present invention
Definitely, clearly, simple illustrate is made on the basic condition of frequency utilization to ultrashort wave radio set first.Ultrashort wave radio set can work
Work is determining frequency, two kinds of frequency modes of frequency hopping；Distribution for surely frequent rate is by a relatively simple, not as accented term in the present invention
It is illustrated, key is the distribution of Hopping frequencies.
Ultrashort wave frequency hopping work refers to that operationally frequency is according to certain hopping pattern from frequency hopping table to ultrashort wave radio set
Case communicated from different frequencies, thus resists interference, while improving the confidentiality of communication data.Ultrashort wave frequency hopping table
In being a networking activity, the working frequency collection table of some radio station subnet deposits radio station subnet this task in the table
When all Frequency points；A kind of order mechanism of frequency selection when frequency hopping pattern is ultrashort wave radio set work, he determines ultrashort
The frequency selecting sequence of ripple radio station operationally, frequency hop sequences typically have higher security classification, do not disclose to external world, typically
Radio station under same system its frequency hopping pattern under a certain identical mode of operation is identical.
The present invention proposes a kind of ultrashort wave radio set Hopping frequencies distribution method, first with means such as frequency monitoring equipment
Collect certain once in movable radio station networking region frequency resource available situation, an available frequency point set is formed, from can
Extraction frequency is concentrated to form the completely self-contained frequency meter of several frequencies with Frequency point（Original frequency table）；Then according to collect this

Attributes of network, multiple frequency meters are extended to by each original frequency table in the way of time-domain multiplexed；Combine on this basis
The real work geographical position of radio station subnet carries out the channeling of regional space, thus improves the frequency profit of ultrashort wave radio set
With rate.
Effectively to implement the advantageous effects of the present invention, the frequency for radio station subnet is distributed, and the present invention follows following
Several principles：
Frequency can use principle：Due to being restricted by circuit design and correlation technique reason, the working frequency of ultrashort wave radio set is often
There is certain restrictive requirement, required such as requiring that working frequency is similar for 0.5MHZ integral multiple, in frequency initial extraction
When, it is necessary to assure each frequency will meet this requirement, therefore in the case where not considering any other factor, ultrashort wave electricity
Frequency in the frequency meter of platform must be 30Mhz, 30.5Mhz, 31Mhz, 31.5Mhz, 32Mhz ... 299.5Mhz,
300Mhz } in frequency, the frequency such as 35.025Mhz, 39.075Mhz is then just unsatisfactory for available principle.The another of principle can be used
Show as on one side on the basis of basic frequency meets demand, it is necessary to consider the factors such as frequency interferences, disabling frequency range, such as
In some special region 60Mhz-this band frequency of 68Mhz because magnetic interference is unavailable, this band frequency of 150Mhz-200Mhz
Because military activity is prohibitted the use of, then disabled frequency must be weeded out by being concentrated in the initial sets point of frequency, and only retaining can
Use frequency.
Frequency equiblibrium mass distribution principle：The working frequency interval of ultrashort wave radio set is 30M -300M, in building for original frequency table
Frequency point should be allowed effectively to be distributed in 30M -300M each interval in vertical, some during frequency usage are thus avoided
The problem of station telecommunication effect caused by temporary factors is poor.By outside interim for example within some work region some periods
Property interference cause low band frequency communication efficiency bad, if the frequency that is operated in the frequency meter of the radio station subnet of the region is whole
For low section of frequency, then the interference that the radio station subnetwork communicating is subject to is just very big, station telecommunication effect is had a strong impact on, if frequency meter
Each frequency range is effectively covered, due to radio station frequency rapid jumping, then influence of the interference to station telecommunication can be greatly lowered.
Frequency point is extracted to be concentrated from frequency using random value principle in the present invention, the usable frequency point set J of such as this networking=
{ 30Mhz, 30.5Mhz, 31Mhz, 31.5Mhz, 32Mhz ... 299.5Mhz, 300Mhz } has N=1000 frequency, ultrashort wave electricity
Platform frequency hopping table B is K=100 frequency specification, then the method for forming an original frequency table is as follows：
M = N;{ having the available frequency in M=1000 }
For I :=0 to K-1 do { frequency table size is 100 frequencies, is that frequency table chooses each frequency }
Begin
R=take random digit 0--M from available frequency points；
I-th frequency in frequency meter B randomly selects R from available frequency point set J；
The R frequency taken is weeded out from available frequency point set J；
M = M -1；Available frequency point quantity reduces one；
End;
Be operated according to the method described above frequency meter set up to be formed B [100]=35.5Mhz, 280Mhz, 75.5Mhz,
21Mhz……178Mhz、36Mhz、225.5Mhz、59.5Mhz}.According to the probability distribution principle of random number, the Frequency point of the table
Also it is substantially distributed in each interval of the high, medium and low frequency range of frequency set.But the original frequency hopping table limited amount being consequently formed, press
1000/100=10 original frequency table of generation is merely able to according to above-mentioned scene.
Synchronized orthogonal frequency time-domain multiplexed principle：According to above-mentioned it is assumed that ultrashort wave radio set is when frequency hopping works, its frequency hopping table
In have 100 Frequency points, the Frequency point in its working frequency table is numbered according to 1-100 for we, the sequence in its frequency meter
Number as shown in frequency hopping table 1 in Fig. 1；Assuming that the frequency hopping pattern in this ultrashort wave radio set subnet is frequency hopping pattern A, according to frequency hopping pattern
A frequency hop sequences become frequency hopping pattern A in one group of new sequence such as Fig. 1 after frequency hopping table 1 is resequenced（From 1 take-off）, due to
The limitation of frequency resource, to ensure that multiple subnets have available frequency resources, therefore considers synchronized orthogonal networking frequency application, will
The Hopping frequencies ski-jump of ultrashort wave radio set makees appropriate interval cyclic shift one new frequency hopping table of formation, by frequency hopping in Fig. 1
Pattern A（From 1 take-off）Frequency meter light saltus step into frequency hopping pattern A in such as Fig. 1 from the 6th（From 6 take-offs）.Due to radio station synchronization onwards
Jump, frequency hopping pattern A in Fig. 1 is had found by analysis（From 1 take-off）With frequency hopping pattern A in Fig. 1（From 6 take-offs）Two frequency meters are at certain
The frequency at one moment is completely different, it can thus be assumed that being two completely brand-new frequency meters, as long as being spaced 1 frequency in theory
Take-off can just form a new frequency meter, according to the frequency distribution principle of synchronized orthogonal networking, can be by an original frequency
Rate table（100 frequencies）Form N=100（Frequency meter frequency specification）/1（Synchronized orthogonal displacement frequency interval）=100 frequency meters,
Full frequency band can form 10（Original frequency table number）*100（Synchronized orthogonal divides frequency meter number）=1000 frequency meters, by
This greatly improves the utilization rate of frequency, and how much synchronized orthogonal frequency meter frequency can be determined according to subnet quantity in real work
Space-number.
Frequency hopping pattern different classifications distribution principle：The frequency distribution of ultrashort wave radio set can be according to synchronized orthogonal group net principle
Frequency meter expansion is carried out, but with the proviso that the frequency hopping pattern of these ultrashort wave radio sets is identical, if the frequency hopping of ultrashort wave radio set
Pattern is different, then can not be distributed unitedly using the method.If the frequency hopping pattern of a certain class ultrashort wave radio set is frequency hopping
Pattern B, equally using the frequency hopping table 1 in Fig. 1 as its working frequency table, then according to frequency hopping pattern B frequency hop sequences by frequency hopping table 1
Become frequency hopping pattern B in one group of new sequence such as Fig. 1 after rearrangement（From 1 take-off）, the frequency hopping pattern B from Fig. 1（From 1 take-off）
With frequency hopping pattern A（From 1 take-off）, frequency hopping pattern A（From 6 take-offs）In frequency 7, frequency 35, frequency 23, frequency 25 ... frequency
15th, frequency 6 etc. all has frequency conflicts.If entering line frequency in the way of synchronized orthogonal networking under same original frequency table
Rate table is distributed, and the radio station subnet used is more, then the possibility of frequency conflicts is bigger, it is therefore desirable to ensure different hopping patterns
Case should carry out laggard line frequency distribution of classifying.For example there is the networking simultaneously of 200 radio station subnets, wherein there are 100 subnets to be jump
Frequency pattern A, another 100 subnets are frequency hopping pattern B, then 5 in 10 original frequency tables can be distributed into frequency hopping pattern A's
Subnet, synchronizes orthogonal networking distribution and 5 frequency meters is expanded into 500 frequency meters again after its classification.Same hopping pattern
Case B 100 radio station subnets share the original frequency hopping table of other 5, and 500 frequencies are expanded in the same way
Table.
Frequency regional space is multiplexed principle：The frequency resource of ultrashort wave radio set is very limited, can in some actual environments
It dividing frequency can be still not able to meet all frequency distribution requirements in the way of synchronized orthogonal networking, then now just use
Frequency regional space is multiplexed principle.Assuming that the frequency influence scope of some ultrashort wave radio set subnet is 30KM, its frequency used
Rate table may be reused again outside 30KM, thus realize the multiplexing of frequency regional space.The multiplexing of frequency regional space
The geographical position of some radio station subnet can not be merely only depended on, but to combine all radio station in surrounding enviroment
Net distribution situation come plan as a whole calculate.
Because the covering of radio station member region is relatively broad in ultrashort wave radio set subnet, algorithm of the invention is a kind of rough mould
The type means of abstraction carries out pool distribution, when calculating the frequency regional impact coverage of radio station subnet, takes main in subnet（It is logical
The central area that main is located at subnet in the case of often）To be calculated, while the coverage of region and the work of radio station subnet
Power（High-power, middle power, small-power）Determined with corresponding radio station characteristic, the parameter can be by user according to actual use
Radio station characteristic is provided, such as high power work frequency influence radius 30KM, middle power operating frequency influences radius 20KM, small-power
Operating frequency influences radius 10KM.
The method have the benefit that：Ultrashort wave radio set is had been widely used in civilian and tactical environment, due to
The a large amount of of ultrashort wave radio set use, and its frequency available resources is limited, often leads to ultrashort wave radio set subnet and goes out in use
Show frequency conflicts, interfere, have a strong impact on the service efficiency of ultrashort wave radio set.The present invention combines the work of ultrashort wave radio set
Feature, it is random from available frequency band to extract frequency formation Hopping frequencies table, will with reference to the characteristic of ultrashort radio station synchronized orthogonal networking
One Hopping frequencies table is effectively decomposed into multiple frequency meters, in conjunction with the work region of ultrashort wave radio set subnet, from regional space
Dimension frequency meter is multiplexed, thus improve the utilization rate of frequency resource, reduce the frequency interferences between each radio station subnet,
Effectively lift the communication performance of ultrashort wave radio set subnet large-scale network-estabilishing.
