[0077] refer to figure 2 , shows a schematic structural diagram of a signal interference device in Embodiment 2 of the present invention. Such as figure 2 As shown, the signal interference device may include: a receiving link 10 , a programmable interference source module 20 , a transmitting link 30 and a phase locked loop (PLL, Phase Locked Loop) 40 .

[0078] in,

[0079] The receiving chain 10 includes: a first antenna 101, a limiter 104, a third switch 102, at least one filter link and a direct link, a second switch 103, a low noise amplifier (LNA, Low Noise Amplifier) ​​connected in sequence ) 105, a first switch 106, a first mixer 107, a first filter 109, a first amplifier 110 and an analog-to-digital converter (A / D, Analog-to-Digital Converter) 111, and, with the first A mixer 107 is connected to a first oscillator 108 .

[0080] The transmission chain 30 includes: a digital-to-analog converter (D / A, Digital-to-AnalogConverter) 308, a second mixer 306, a second fi...

Embodiment 3

[0100] Based on the same inventive concept as the above device embodiment, refer to image 3 , shows a flow chart of steps of a signal interference method in Embodiment 3 of the present invention. In this embodiment, the signal interference method includes:

[0101] Step 302: Receive an air signal through a receiving link, convert the air signal into a digital signal, and send the digital signal to a programmable interference source module.

[0102] Step 304: Perform desynchronization processing on the digital signal through the programmable interference source module, generate a transmission modulation signal according to the desynchronization processing result, and send the transmission modulation signal to a transmission link.

[0103] Step 306: Receive the transmit modulation signal through a transmit link, convert the transmit modulated signal into a modulated interference signal, and radiate the modulated interference signal into the air.

[0104] It can be seen that i...

Abstract

The invention provides a signal interference device and method. The device comprises a receiving link which is used for receiving an air signal and converting the air signal into a digital signal, andsending the digital signal to a programmable interference source module; the programmable interference source module which is used for carrying out de-synchronization processing on the digital signal, and generating a transmission modulation signal according to the de-synchronization processing result, and transmitting the transmitting modulating signal to a transmitting link; the transmitting link which is used for receiving the transmitting modulating signal, converting the emission modulating signal into a modulation interference signal, and radiating the modulation interference signal tothe air. According to the invention, the problem that a terminal signal interference device in the prior art is high in power requirement and relatively large in power consumption, and cannot completely block the terminal communication.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a signal interference device and method. Background technique [0002] With the rapid development of the mobile communication industry, the connectivity between people has increased dramatically, but at the same time, convenient communication methods have also increased the number of venues that have special requirements for interoperability (such as examination rooms, confidential meetings, Operational difficulty of signal interference from prisons, etc. [0003] The terminal signal jammer is mainly aimed at various examination rooms, schools, gas stations, churches, courts, libraries, conference centers (rooms), theaters, hospitals, governments, finance, prisons, public security, military centers and other places where the use of terminals for communication is prohibited . Through the terminal signal jammer, the terminal can be in the state of searching the network, no...
