In addition, frequency division duplex refers in mode of frequency division duplexing, that is, fdd mode used by the frequency duplex communications interface
The transmission of uplink and downlink carries out over different frequencies respectively.
In the first and second generation cellular system, it is substantially using FDD technology and realizes duplex transmission.Especially
In generation cellular system, what it is due to transmission is continuous baseband signal, it is necessary to the uplink and downlink of duplex is provided with different frequencies
Link channel.When transmitting continuous information using FDD technology in first generation cellular system, transmitting-receiving both ends must all have generation different
The frequency synthesizer of carrier frequency must also have one to prevent transmitting signals leakiness to the duplex filtering of receiver in receiving end
Device.In addition, certain frequency interval will be had by receiving and dispatching between carrier frequency for the ease of the production of duplexer.In the second generation
In the systems such as GSM, IS-136 and IS-95, FDD technology is also used.In such systems, due to information be with slotted mode into
Row transmission, transmitting-receiving can carry out in different time slots, and the transmitting signal of mobile station or base station will not generate this receiver
Interference.So although with FDD technology, do not need expensive duplexer filter yet.
The characteristics of fdd mode is the system on two symmetrical frequency channels of separation (uplink and downlink frequency interval 190MHz)
It is received and is transmitted, reception and transmission channel are separated with protection frequency range.
Using technologies such as packet switch, the bottleneck of two generations development can be broken through, realizes high-speed data service, and frequency spectrum benefit can be improved
With rate, increase power system capacity.But FDD must use pairs of frequency, i.e., third generation business is provided in the bandwidth of every 2x5MHz.
Which can make full use of the frequency spectrum of uplink and downlink when supporting symmetrical service, but in asymmetrical packet switch (internet) work
When making, the availability of frequency spectrum then substantially reduce (due to low ascending load, the availability of frequency spectrum is caused to reduce about 40%), in this regard,
The advantage that tdd mode has FDD incomparable.

Benefit manages image and the band logical retains image, and the gain process image and the band logical are retained image integration to obtain simultaneously
Image after output integration；
Suspect's authentication equipment is connect with described image integration equipment, for receiving image after the integration, for based on default
Human facial profile from each spectators' facial area is identified after the integration in image, to each spectators' facial area execute with
Lower operation: the facial characteristics for being based respectively on each suspect carries out suspect's identification to spectators' facial area, and is reflecting
Not Cheng Gong when, issue the wanted circular number of corresponding suspect.
2. auditorium identity as described in claim 1 scene identification system, it is characterised in that:
In the automatic gain equipment, the DYNAMIC DISTRIBUTION range of the bandpass filtering image is wider, to the bandpass filtering figure
As the gain process dynamics executed is smaller.
3. auditorium identity as claimed in claim 2 scene identification system, which is characterized in that the system also includes:
Frequency duplex communications interface is connect with suspect's authentication equipment, and the wanted circular for that will correspond to suspect is numbered wireless
It is sent at nearest police service control centre server.
4. auditorium identity as claimed in claim 3 scene identification system, it is characterised in that:
In the pre-processing device, intensification processing is carried out to each target shape detected, to obtain at corresponding intensification
Reason image includes: to obtain each pixel that each target shape is formed in the target image to be processed, and what be will acquire is each
The pixel value of pixel is reduced to 60 the percent of itself numerical value.
5. auditorium identity as claimed in claim 4 scene identification system, it is characterised in that:
In the region corrective, numerical value adjustment is carried out to each region segmentation threshold value based on the whole segmentation threshold
It include: that the size of the difference based on whole segmentation threshold to each region segmentation threshold value carries out the region segmentation threshold value
Numerical value adjustment.
6. auditorium identity as claimed in claim 5 scene identification system, it is characterised in that:
The parameter preset threshold range is made of parameter preset upper limit threshold and parameter preset lower threshold；
Wherein, the parameter preset upper limit threshold is less than the parameter preset lower threshold.
7. auditorium identity as claimed in claim 6 scene identification system, it is characterised in that:
In the region corrective, the size of the difference pair based on the whole segmentation threshold to each region segmentation threshold value
The region segmentation threshold value carry out numerical value adjustment include: region segmentation threshold value adjusted be the region segmentation threshold value with it is described
The sum of difference a quarter.
8. auditorium identity as claimed in claim 6 scene identification system, it is characterised in that:
In the region corrective, the size of the difference pair based on the whole segmentation threshold to each region segmentation threshold value
The region segmentation threshold value carry out numerical value adjustment include: region segmentation threshold value adjusted be the region segmentation threshold value with it is described
The sum of difference half.
