Description
Technical field
The present invention relates to wireless communication technique more particularly to a kind of Communication Jamming measurement methods, device and system.
Background technique
With being constantly progressive for radio technology, various radio traffics are emerged in multitude, and radio traffic institute
The frequency spectrum resource of support is limited, and is continuously increased in face of people to bandwidth demand, and frequency spectrum resource shows extremely nervous
Situation；And on the other hand under traditional fixed frequency spectrum allocation model, the utilization rate of frequency spectrum resource is not but high.In a sense
It says, being this fixed allocation causes the extremely nervous situation of frequency spectrum resource to the frequency spectrum distribution system of authoring system.And it recognizes
Radio technology has just broken traditional frequency spectrum fixed allocation system, and frequency spectrum is dynamically distributed between system, is improved
The utilization efficiency of frequency spectrum.Typically, simple voice such as has been not content with the continuous improvement of people's periodic traffic demand
Data communication, specific gravity of the video stream media business in people's communication life are continuously increased, this requires bigger bandwidth as branch
Support, it is nervous that International Mobile (International Mobile Telecom, IMT) system shows unprecedented frequency spectrum
Situation, and for radio data system (Television, TV) for, largely there is available for frequency spectrum resource
Space, such as certain radio data system frequency spectrums in certain areas and are not used by；Certain radio data system frequency spectrums are in somewhere
Though there is covering, certain moment are not used, and overall utilization rate is relatively low.And the fixed frequency spectrum method of salary distribution make it is above-mentioned not by
The frequency spectrum resource used can not re-use, such as can not be for used in IMT system.It is logical by cognitive radio technology IMT system
The acquisition to radio data system information is crossed, waits for an opportunity to occupy Broadcast and TV system not used frequency spectrum resource on room and time, i.e.,
TV blank frequency spectrum (TV White Space, TVWS), to improve the utilization rate of radio data system frequency spectrum, improves IMT system
The situation for frequency spectrum anxiety of uniting.
This subsystem waits for an opportunity to occupy the frequency spectrum usage mode of main system frequency spectrum resource, it is necessary to assure effective to primary user
Ground protection cannot cause harmful interference to main system user when that is, subsystem uses main system frequency spectrum resource, this is cognition nothing
The precondition that line power technology can be realized.In order to reach such purpose, subsystem optionally utilizes frequency spectrum perception technology
Monitor the appearance of primary user, so as to when finding that the primary user on frequency spectrum resource occupied by subsystem reappears, in time
The frequency spectrum resource is exited, the interference to primary user is avoided.
The prior art is the limitation by maximum transmission power, realizes the protection to main system, i.e., main system is by secondary
System interference in a certain range, by taking DTV (Digital Television, DTV) system as an example, it is considered that DTV system
Location probability loss of uniting is as noiseless lower than 0.1%.If maximum power limitation is wide, principal series blanket insurance may be cannot achieve
Shield；If maximum power limitation is excessively stringent, may cause subsystem does not have TVWS frequency spectrum available.Therefore, how accurately
Know subsystem base station to main system coverage area reference point interference relationships become an inevitable basic fundamental
Problem is the accurate premise for obtaining maximum transmission power limitation.The reference point of subsystem base station and main system coverage area
Relationship is shown in Figure 1.But currently available technology can't accurately know subsystem base station to main system coverage area
The interference relationships of reference point.
In addition, another necessary condition that TVWS can be used is that each subsystem can be total in the realization on TVWS
It deposits, it is non-interfering to use TVWS resource, i.e., it interferes in tolerance to each other.Interference between each subsystem base station is closed
Be it is shown in Figure 2, due to configuration TVWS running parameter before, system can not be known between each cell (cell) each other in advance
Interference relationships and then not can guarantee subsystem minizone therefore, it is impossible to accurately formulate frequency spectrum distribution, power distribution decision
Coexist each other.
