Embodiment
With reference to the accompanying drawings embodiments of the invention are elaborated.
Fig. 1 is take on the sly the pie graph of mobile communication terminal of camera detection function of lift-launch of the present invention.As shown in the figure, it comprises following content: antenna 100, construct wireless network with the wireless connection device between the base station; Duplexer portion 101 carries out transmitt or receive signal with above-mentioned antenna 100; Power amplifier module (poweramplifier module:PAM) 102 is in order to output to received signal the electric power of duplexer portion 101 amplifying signals; Low noise amplifier (low noise amplifier:LNA) 103 amplifies received signal; Lifting converter 104 comprises the signal that transmits to the base station and is upgraded to rising converter and being reduced to the converter that falls of base wave band from the signal that antenna 100 receives of suitable output frequency wave band; Data processing division 105 receives data conversion or send for being fit to; The 1st regional oscillator (local oscillator) 106 is adjusted into to signal that is input to above-mentioned lifting converter 104 and the suitably used frequency band of output signal; FIR filter 109 is searched the frequency band that leaks in the camera of taking on the sly; The 2nd regional oscillator 107, the frequency band of control FIR filter 109; Area oscillator control part (to call the LO control part in the following text) 108 is controlled 106,107 operations of above-mentioned the 1st, 2 regional oscillator; Timing control part 110, relevant duplexer portion 101 and the data processing division of whether believing with signal transmitting and receiving 105 of control; Handling procedure portion 111 determines operating time of the 1st, 2 regional oscillators 106,107.
Receive the camera seeking requirement of taking on the sly by the keypad of mobile communication terminal, the 111 meeting perception of handling procedure portion are in order to search the leakage frequency executable operations of the camera of taking on the sly.The detection principle of camera of taking on the sly is, the scope of application of the camera of taking on the sly mainly is 348Mhz-2400Mhz, so perception is equivalent to these frequency, and the camera of taking on the sly around just knowing.
At first, the control LO of handling procedure portion 111 control parts 108, the phase of taking on the sly machine testing in order to allow the 2nd regional oscillator 107 search to take on the sly camera to leak frequency, are regulated FIR filter 109 and are scanned high frequency band from low frequency wave bands constantly.That is, frequency band is risen gradually, be raised to the leakage frequency of the camera of taking on the sly.
On the other hand, wireless network control utilizes LO control part 108 controls the 1st regional oscillator 106 constantly once more, and the leakage frequency band of the camera of taking on the sly is converted to the wireless network wave band.At this moment, data processing division 105 utilizes the control signal of timing control part 110 to handle the wireless network signal in lifting converter 104.
The effect of lifting converter 104 is to utilize the signal wireless network frequency band figure signal of the 1st regional oscillator 106.When data processing division 105 sends, conversion position digital signal behind the incoming speech signal, do Digital Signal Processing after, rises converter 104 and transmits, the use signal of handling when unlimited output.
On the contrary, after doing Digital Signal Processing from the signal that falls converter 104 inputs, be transformed to analog signal and export during reception with loud speaker.
In addition, above-mentioned handling procedure portion 111 is implemented as in the middle of the operation that detects the camera of taking on the sly also from wireless network and sends signal for paging receiving channel (paging channel), the moment of paging receiving channel, after wireless network frequency band and its corresponding level of power be suitable for wireless network once more and recover, handle the leakage that continues to detect the camera of taking on the sly behind the draft.
That is, as shown in Figure 2, use complete dual communication and half duplex communication system with, do not have service terminal also can apply flexibly the camera detection function of taking on the sly when utilizing receipt of call by wireless network or paging channel.
Here, the half mutual rightabout of dual communication is communicated by letter, when not overlapping in time, promptly, communication the time, cannot communicate by letter on the other hand conversely on the one hand, just can communicate by letter in the other direction after having only the communication of end in the past, complete dual communication sends and receives and can carry out simultaneously when time-interleaving is feasible.
Utilize full duplex communication system in wireless network control field, (idle time) utilized half dual mode when shut down wireless network control signal transmitting-receiving back, scanned the operation of the leakage frequency band of the camera of taking on the sly once more repeatedly.
When the leakage frequency band of camera is taken in detection on the sly, utilize the signal fast fourier transform (FFT:fast fourier transform) that is input to FIR filter 109 to find frequency, will send to handling procedure portion 100 to it.
FFT is the algorithm for the Fourier transform of discrete data, and its speed is more and more faster in calculating process, so utilize it.
Can reference, send enlarging section PAM102, send from rising the small-signal of converter input; Receive enlarging section LNA103, allow and fall the signal of converter processing from antenna 100 inputs.
In detailed description as above, utilize to the present invention relates to have when taking the mobile communication terminal of camera on the sly, for detection take on the sly the camera receiving and transmitting signal during also can use the mobile communication service, increased user convenience.Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
