Description

Electronic device for anti-jamming and its operation method {ELECTRONIC APPARATUS FOR ANTI-JAMMING AND OPERATION METHOD THEREOF}

Embodiments of the present specification relate to an electronic device for anti-jamming and a method of operating the same. Specifically, an embodiment of the present specification relates to an adaptive anti-jamming satellite communication system, and when a jamming signal is applied to a satellite, not only the receiving node but also the transmitting node can receive a signal containing the same jamming signal. This is about a technique for responding with a pattern promised in a jamming response engine using .

The satellite communication system is a system that provides simultaneous service to multiple subscribers located in wide areas such as land/mountains/sea, regardless of terrestrial infrastructure, and is used in a variety of ways in the military and private sectors. Satellite communication has a very wide communication range that a single satellite can service, has few restrictions on geographical location, has relatively uniform communication quality, and can transmit using radio waves in the several GHz to tens of GHz bands. Additionally, broadcasting, which can distribute the same information to multiple points at the same time, and multiple access, which can set up lines between multiple points, are possible. On the other hand, there are also disadvantages such as transmission delay due to long-distance transmission, reduced reception signal strength, weak security due to the ease of reception method, and being affected by climate such as rainfall attenuation and solar interference due to the use of high frequencies. In particular, since the specifications of satellite communication repeaters (for example, altitude, latitude, longitude, and frequency of use, etc.) are public, they are vulnerable to jamming, and in times of war or emergency, they are considered the number one source of disturbance for warring countries.

In general, in a communication system, when other radio waves invade some bands within the signal band, they cause interference and the communication quality deteriorates. Anti-jamming technology is a technology that protects satellite navigation from external jamming signals. Anti-jamming techniques in satellite communication to prevent signal jamming include the use of active repeaters or satellite repeater antenna nulling techniques. Antenna nulling is a technique to intentionally exclude interference signals by removing jamming signals coming from a satellite repeater in a specific area. Compared to a typical repeater that consists of a simple RF reception/amplification/transmission structure of a receiver, amplifier, and transmitter, an active repeater provides RF reception, down-conversion, signal processing at IF or baseband (jamming signal nulling, etc.), up-conversion, amplification, It consists of transmission. However, the existing active repeater or antenna nulling technique can only be utilized by implementing the technique during satellite design and production, so its application to commercial broadcasting/communication satellites and communication satellites already in service may be limited.

Therefore, an adaptive anti-jamming satellite communication system that can effectively respond to jamming signals while interoperating with communication satellites already in service is required.

The embodiment of the present specification is proposed to solve the above-mentioned problem by detecting a jamming signal from a signal received from an electronic device and generating a waveform change command for anti-jamming based on the characteristic information of the detected jamming signal. The purpose is to build a stable satellite communication system capable of immediate response to jamming signals.

According to an embodiment of the present specification, the receiver includes a first receiver for receiving the second signal and a second receiver for receiving a loopback signal of the first signal by a satellite, and the jamming signal is transmitted to the second signal. It is characterized in that it is detected from at least one of a signal and the loopback signal.

According to an embodiment of the present specification, the control unit: determines whether the network is synchronized based on the network performance information, and when the network is not synchronized, the bandwidth of the jamming signal is compared to the bandwidth of the received signal. Determine whether the ratio exceeds the first threshold, and if it is determined that the ratio exceeds the first threshold, transmit a spread spectrum waveform change command to the receiver based on characteristic information of the jamming signal. It is characterized in that it is further configured to do so.

If a jamming signal exists in an existing satellite communication system, communication quality may deteriorate or communication may be interrupted due to interference from other radio waves within the signal band. Response to jamming signals may be desirable to eliminate the source of the jamming signal, but maintaining communication links through immediate response is difficult. According to an embodiment of the present specification, when a jamming signal is detected in the receiver, the control unit of the electronic device determines the characteristics of the jamming signal in a situation where communication is not possible even after removal of the jamming signal source, and changes the waveform of the transceiver to respond to the jamming signal. By responding immediately, a stable satellite communication system can be established.

1 is a diagram schematically showing each configuration of an anti-jamming system according to an embodiment of the present specification.

Referring to FIG. 1, an anti-jamming system including electronic devices 100 and 110 and a communication satellite 120 is shown. The anti-jamming system may be referred to as an adaptive anti-jamming satellite communication system. The electronic devices 100 and 110 can perform wireless communication to transmit and receive information through the communication satellite 120, and the communication satellite 120 travels to the Earth for the purpose of relaying communication signals between the electronic devices 100 and 110. May include orbiting satellites. In one embodiment, the jamming signal may be applied directly to the electronic devices 100 and 110 and the communication satellite 120.

The electronic device 100 may include a transmitter 101 that transmits a signal, a receiver 103 that receives a signal, and a control unit 102 that controls the transmitter 101 and the receiver 103. In one embodiment, the receiving unit 103 may detect a jamming signal that reduces communication quality or disrupts communication from a received signal, and transmits information about the detected jamming signal and network performance information to the control unit 102. The control unit 102 may include an engine that performs an anti-jamming technique in response to the characteristics of the detected jamming signal. In one embodiment, the control unit 102 integrates the jamming signal information and network performance information received from the receiver 103 and feeds back a waveform change command for anti-jamming to the transmitter 101 and/or the receiver 103. , a transmission output level change command can be fed back to the transmitter 101. This can be equally applied to the electronic device 110 including the transmitter 111, the control unit 112, and the receiver 113.

In one embodiment, the receiving unit 103 of the electronic device 100 receives a signal transmitted from the transmitting unit 111 of the electronic device 110 (dotted arrow) and a signal transmitted from the transmitting unit 101 of the electronic device 100 ( A loopback signal (solid arrow) can be received. One of the characteristics of satellite communication is that the signal it transmits can be received through satellite relay. Utilizing these characteristics, the receiver 103 of the electronic device 100 provides a loopback function in which signals transmitted from the electronic device 100 as well as signals transmitted from other electronic devices 110 are returned via the communication satellite 102. Signals can be received together. In other words, the signal (solid arrow) transmitted from the transmitting unit 101 of the electronic device 100 is a signal transmitted to the receiving unit 113 of the electronic device 110 via the communication satellite 120, and the communication satellite 120 It may be composed of a satellite loopback signal that returns to the receiving unit 103 of the electronic device 100, and each receiving unit 103, 113 of the electronic device 100, 110 determines the characteristics of the jamming signal through the same received signal. You can check it.

For example, when a jamming signal is detected in the electronic device 110 and changes the waveform of the transmission signal, the electronic device 100 that transmits and receives the signal to the electronic device 110 changes the waveform of the electronic device 110. Smooth communication can be performed only when information is recognized and the same waveform change command is issued to the receiver 102 of the electronic device 100. At this time, the electronic device 100 receives not only a signal transmitted from another electronic device 110 (dotted line arrow) among the signals received by the receiver 102, but also a satellite loopback signal (solid line arrow) of the signal transmitted from the electronic device 100. By obtaining waveform change command information of the electronic device 110, corresponding commands can be issued to the transmitter 101 and the receiver 102 of the electronic device 100, and thus You can immediately respond to jamming signals by receiving loopback signals.

FIG. 2 is a diagram schematically showing each configuration of an electronic device according to an embodiment of the present specification.

Referring to FIG. 2 , the electronic device 200 may include a transmitter 201, a control unit 202, and a reception unit comprised of a first reception unit 203 and a second reception unit 204. The first receiver 203 may include a receiver configured to receive a signal (red dotted line) transmitted from another node or electronic device, and the second receiver 204 may be transmitted from the transmitter 201 of the electronic device 200. It may include a loopback receiver configured to receive a loopback signal from a satellite (solid blue line).

In one embodiment, the first receiver 203 detects jamming signals that cause communication quality deterioration or communication disruption by applying a notch filter-based anti-jamming algorithm to the received signal and performs notch filtering on the jamming signal. can do. The first receiver 203 receives characteristic information of the jamming signal, such as the bandwidth of the jamming signal and the jamming-to-signal ratio (JSR), whether it is synchronized, and the bit error rate (BER) from the received signal. ) can be checked and transmitted to the control unit 202.

In one embodiment, the second receiver 204 detects a jamming signal by applying a notch filter-based anti-jamming algorithm to the loopback signal transmitted from the transmitter 201 of the electronic device 200 and returned through a communication satellite. Notch filtering can be performed on The second receiver 204 may check the jamming signal characteristic information and network performance information from the loopback signal and transmit them to the control unit 202.

In one embodiment, the control unit 202 may check jamming characteristics based on information obtained from the first receiver 203 or the second receiver 204 and perform the role of an engine corresponding thereto. In one embodiment, the control unit 202 may feed back a command for waveform change to the first receiver 203 based on the characteristic information of the jamming signal and network performance information received from the first receiver 203. In one embodiment, the control unit 202 sends a command for waveform change based on the characteristic information and network performance information of the jamming signal received from the second receiver 204 to the transmitter 201 as well as the second receiver 204. Feedback can be provided (green solid line). In one embodiment, the control unit 202 may feed back a transmission output level change command to the transmitter 201 based on the characteristic information and network performance information of the jamming signal received from the second receiver 204 (green solid line). . In this way, the control unit 202 can process the other node transmission signal received from the first reception unit 203 and the own node transmission loopback signal received from the second reception unit 204 in parallel.

For example, the waveform change command fed back from the control unit 202 to the receiving unit and/or the transmitting unit may be based on an adaptive modulation and coding (AMC) technique. The AMC technique is a link adaptation technique that can dynamically change the modulation technique and coding technique according to the propagation status of the channel in wireless communication. When communication quality deteriorates due to jamming, the characteristic information of the jamming signal confirmed by the receiver is used. Based on this, communication quality can be improved by changing the waveform of the signal transmitted or received by the transmitter or receiver, respectively. For example, if communication is not possible due to a jamming signal in a transceiver using the 8PSK modulation method with a coding rate of 3/4, the control unit 202 transmits and receives a waveform using the QPSK modulation method with a coding rate of 3/4 to prevent jamming. You can command the transmitter and receiver to change. In this way, when a jamming signal is detected in the receiving unit, the control unit of the electronic device determines the characteristics of the jamming signal in a situation where communication is not possible even after the jamming signal source is removed, and immediately responds to the jamming signal by changing the waveform of the transceiver to ensure stable operation. A satellite communication system can be built.

Figure 3 is a flowchart showing a process for checking and responding to jamming characteristics of a control unit for a received signal according to an embodiment of the present specification. Each step of FIG. 3 may be performed by the control units 102 and 112 of FIG. 1 and the control unit 202 of FIG. 2, and the received signal may be received by the first receiver 203 of FIG. 2.

In step 301, the control unit may collect jamming signal information confirmed by the receiver and check the characteristics of the jamming signal.

In step 302, the control unit determines whether a jamming signal is detected in the received signal, and if no jamming signal is detected, the control unit moves to step 303 to maintain the current network.

If the control unit determines that a jamming signal is detected, the control unit may proceed to step 304 to determine whether the network is synchronized. If the control unit determines that network synchronization is secured, even if a jamming signal is detected, the control unit determines that there is no serious problem with communication and moves to step 303 without additional action to maintain the network.

If the control unit determines in step 304 that the received signals are not synchronized, that is, if it is determined that the frequencies between the received signals are different and the phase relationship cannot be accurately controlled, in steps 305 to 307, the control unit determines that the received signals are not synchronized. You can command to change the form to an anti-jamming waveform. In one embodiment, the control unit may transmit a change command to the same waveform to the transmitter based on jamming signal information confirmed by the loopback receiver (e.g., the second receiver 204 in FIG. 2).

In step 305, if it is determined that the network is not synchronized, the control unit may determine whether the ratio of the bandwidth of the jamming signal to the bandwidth of the signal received from the receiver exceeds the first threshold. If it is determined that the ratio exceeds the first threshold, the control unit may generate a spread spectrum waveform change command based on the characteristic information of the jamming signal in step 307 and transmit it to the receiver. If the ratio of the bandwidth of the jamming signal to the bandwidth of the received signal exceeds the first threshold, the control unit determines it is wideband jamming and can change the waveform of the receiver to a spread spectrum waveform to ensure robustness of communication. . Meanwhile, if the control unit determines that the ratio of the bandwidth of the jamming signal to the bandwidth of the received signal does not exceed the first threshold, it determines narrowband jamming and instructs the receiver to change the waveform to a lower modulation and coding level in step 306. You can command. In this way, the electronic device can stably manage the data transmission rate and secure communication robustness by adaptively determining a waveform change command for anti-jamming based on the ratio of the bandwidth of the jamming signal.

Figure 4 is a flowchart showing the process of checking and responding to jamming characteristics of a control unit for a loopback reception signal according to an embodiment of the present specification. Each step of FIG. 4 may be performed by the control units 102 and 112 of FIG. 1 and the control unit 202 of FIG. 2, and the loopback reception signal may be received by the second receiver 204 of FIG. 2. .

In step 401, the control unit may collect jamming signal information from the loopback signal confirmed by the receiver and check the characteristics of the jamming signal.

In step 402, the control unit determines whether a jamming signal is detected in the loopback reception signal, and if no jamming signal is detected, the control unit moves to step 403 to maintain the current network.

If the control unit determines that a jamming signal is detected, the control unit moves to step 404 and can determine whether the network is synchronized. If it is determined in step 404 that the network is not synchronized, the control unit may command the transmitter to change the waveform to an anti-jamming waveform in steps 405 to 407 to secure network synchronization.

In step 405, if it is determined that the network is not synchronized, the control unit may determine whether the ratio of the bandwidth of the jamming signal to the bandwidth of the signal received at the receiver exceeds the first threshold. If it is determined that the ratio exceeds the first threshold, the control unit may generate a spread spectrum waveform change command based on the characteristic information of the jamming signal in step 407 and transmit it to the transmitter. If the ratio of the bandwidth of the jamming signal to the bandwidth of the received signal exceeds the first threshold, the control unit determines it is wideband jamming and can change the waveform of the transmitter to a spread spectrum waveform to ensure robustness of communication. . Meanwhile, if the control unit determines that the ratio of the bandwidth of the jamming signal to the bandwidth of the received signal does not exceed the first threshold, it determines narrowband jamming and instructs the transmitter to change the waveform to a lower modulation and encoding level in step 406. You can command. In this way, the electronic device can stably manage the data transmission rate and secure communication robustness by adaptively determining a waveform change command for anti-jamming based on the ratio of the bandwidth of the jamming signal. Additionally, the electronic device can reduce overhead by configuring an adaptive algorithm through receiving its own loopback signal without separate wireless feedback information.

Meanwhile, the control unit may determine whether the network is synchronized in step 404, and if it is determined that the network is synchronized in step 404, it may determine whether the network performance is satisfactory in step 408. This can be determined based on network performance information obtained from the receiver that receives the loopback signal, and the network performance information may include information on bit error rate, synchronization, etc. If the control unit determines that the network performance is satisfied in step 408, even if a jamming signal is detected, the control unit determines that there is no serious problem with communication and moves to step 403 without additional action to maintain the network. Meanwhile, if the control unit determines in step 408 that the network performance is not met (for example, if the bit error rate exceeds the threshold), in step 409, the control unit issues a transmission level adjustment command from the transmitter to ensure stable communication performance. It is generated and transmitted to the transmitter, thereby securing the margin of signal-to-noise ratio. In one embodiment, the control unit may check the bit error rate of the network based on network performance information, and if the bit error rate exceeds the second threshold, generate a transmission level improvement command and transmit it to the transmitter.

In one embodiment, the waveform change command of the controller may be generated based on at least one of the bandwidth of the jamming signal, jamming signal strength (JSR), and synchronization technique. The synchronization technique may be related to the type of code used during initial synchronization of the network and may include, for example, a synchronization technique based on Reed-Muller codes. In this way, the control unit considers the characteristic information and network performance information of the jamming signal obtained from the receiver and transmits a waveform change command appropriate to the current situation to the receiver and/or transmitter to immediately respond to the jamming signal and establish a stable satellite communication system. It can be built.
