Description
Technical field
The present invention relates to wireless communication technology, particularly relate to a kind of Communication Jamming method of measurement, device and system.
Background technology
Along with the continuous progress of radiotechnics, various radio traffic emerges in multitude, and the frequency spectrum resource that radio traffic is relied on is limited, and in the face of people are to the continuous increase of bandwidth demand, frequency spectrum resource shows very nervous situation; And on the other hand under traditional fixed frequency spectrum allocation model, the utilance of frequency spectrum resource is but not high.Saying in a sense, is that this fixed allocation causes the very nervous situation of frequency spectrum resource to the spectrum allocation may system of authoring system.And cognitive radio technology has just broken traditional frequency spectrum fixed allocation system, by frequency spectrum dynamic assignment between system, improve the utilization ratio of frequency spectrum.Typically, as improving constantly along with people's periodic traffic demand, be not content with simple voice data communication, the proportion of video stream media business in people's communication life constantly increases, this requires that larger bandwidth is as support, International Mobile (International Mobile Telecom, IMT) system shows the nervous situation of unprecedented frequency spectrum, and for radio data system (Television, TV), frequency spectrum resource also exists available space to a great extent, as some radio data system frequency spectrum is not used in certain areas, though some radio data system frequency spectrum has covering in somewhere, some moment is not used, and overall utilization rate is on the low side.And fixing spectrum allocation may mode makes above-mentionedly cannot not re-used by the frequency spectrum resource used, such as, cannot be that IMT system is used.By cognitive radio technology IMT system by the acquisition to radio data system information, wait for an opportunity to take Broadcast and TV system untapped frequency spectrum resource on room and time, i.e. TV blank frequency spectrum (TV White Space, TVWS), thus improve the utilance of radio data system frequency spectrum, improve the situation of IMT system spectrum anxiety.
This subsystem waits for an opportunity to take the frequency spectrum usage mode of main system frequency spectrum resource; must ensure effectively to protect primary user; namely, during subsystem use main system frequency spectrum resource, can not cause harmful interference to main system user, this is the precondition that cognitive radio technology can realize.In order to reach such object, subsystem optionally utilizes frequency spectrum perception technology to monitor the appearance of primary user, when finding that the primary user on frequency spectrum resource shared by subsystem reappears, exiting described frequency spectrum resource in time, avoiding the interference to primary user.
Prior art is the restriction by maximum transmission power; realize the protection to main system; namely main system is subject to subsystem interference within the specific limits; with Digital Television (Digital Television; DTV) system is example, it is generally acknowledged that the loss of DTV alliance probability is noiseless lower than 0.1%.If maximum power restriction is wide, then possibly cannot realize main system protection; If maximum power restriction is too strict, then subsystem may be caused not have TVWS frequency spectrum to use.Therefore, how accurately knowing that subsystem base station becomes an inevitable basic technique problems to the interference relationships of the reference point of main system coverage, is the prerequisite accurately obtaining maximum transmission power restriction.The relation of the reference point of subsystem base station and main system coverage is shown in Figure 1.But currently available technology accurately can't know the interference relationships of subsystem base station to the reference point of main system coverage.
In addition, TVWS operable another one necessary condition is that each subsystem can coexist in the realization on TVWS, and non-interfering use TVWS resource, namely disturbs in tolerance to each other.Interference relationships between each subsystem base station is shown in Figure 2, due to before the running parameter of configuration TVWS, system cannot to know between each community (cell) interference relationships each other in advance, therefore, accurately cannot formulate spectrum allocation may, power division decision-making, and then coexisting each other of subsystem minizone cannot be ensured.
