Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of satellite communication, and particularly relates to a communication and perception integrated adaptive anti-jamming satellite communication system. BACKGROUND

[0002] The communication and perception integration refers to an information processing technology for realizing coexistence, fusion and cooperation of communication and perception functions based on sharing of software and hardware resources. By realizing mutual benefits of communication and perception in the same system, the communication and perception integration can significantly improve the spectrum efficiency and hardware utilization efficiency of the system.

[0003] The adaptive anti-jamming satellite communication is a typical application of the communication and perception integration. In order to cope with diversified electromagnetic threats of different levels and intensities, the satellite communication should have an adaptive anti-jamming capability, that is, the communication waveform is adaptively adjusted according to the current communication state and the perception result.

[0004] Commonly used anti-jamming communication waveforms include a direct spread waveform and a frequency hopping waveform. The direct spread waveform takes a direct sequence spread spectrum technology as a core, and combines coding, modulation, burst and other technical means to realize anti-jamming communication. The frequency hopping waveform takes a frequency hopping technology as a core, and combines coding, modulation, diversity and other technical means to realize anti-jamming communication. The direct spread waveform and the frequency hopping waveform are variable according to the information rate grading, and each rate grade has different interference tolerances under different interference patterns, and the specific values can be determined in advance. At present, the coupling degree of the communication waveform and the interference perception is low, and the adaptive capability is not strong, and the satellite anti-jamming capability needs to be further improved. SUMMARY

[0005] The application aims at the defects and deficiencies of the prior art, and provides a communication and perception integrated adaptive anti-jamming satellite communication system to realize improvement of the satellite anti-jamming communication capability.

[0006] The application realizes the following technical scheme:

[0007] A communication and perception integrated adaptive anti-jamming satellite communication system comprises:

[0008] A communication subsystem is used for completing signal processing functions from service access to service output; a sending end of the communication subsystem sends corresponding data frames in a burst time slot according to a set rate grade according to control subsystem signaling, and a receiving end of the communication subsystem realizes adaptive reception by analyzing guide area information of the data frames, and simultaneously reports a communication state to the control subsystem;

[0009] A perception subsystem is used for completing interference detection and identification; the perception subsystem performs interference perception after extracting interference signals, and reports a perception result to the control subsystem;

[0010] The control subsystem formulates corresponding anti-interference strategies according to the communication state and the sensing result and issues the execution; the anti-interference strategies include interference suppression strategies and interference avoidance strategies; the interference suppression strategies achieve the anti-interference purpose by adjusting the rate profile; the interference avoidance strategies achieve the anti-interference purpose by adjusting the frequency hopping pattern.

[0011] Further, in the signal processing of the communication subsystem, the direct spread waveform and the frequency hopping waveform adopt the same frame structure design, and data transmission is performed in the form of bursts; each burst time slot corresponds to a frame; each frame is composed of a guide area, a data area and a protection area; the guide area includes a synchronization code, a unique word and a mode word, which are used to identify the frame start position, eliminate phase ambiguity and indicate the data area rate profile respectively; the data area includes a plurality of coding blocks, which are set to different lengths according to the corresponding information rate profile; wherein the frequency point hopping of the frequency hopping waveform is completed in the protection area.

[0012] Further, the sensing subsystem extracts the interference signal according to the consistency of the sensing bandwidth and the communication bandwidth, as follows:

[0013] When the communication subsystem adopts the direct spread waveform, signal acquisition is completed in the protection period of each time slot, and the separation of the interference signal is realized in the time domain; when the frequency hopping waveform is adopted, signal acquisition is performed according to the frequency hopping period interval after the completion of the frequency point switching, and then the power spectrum is calculated and smoothed after the collected signal is transformed into the frequency domain, and the separation of the interference signal is realized in the frequency domain.

[0014] Further, the sensing subsystem performs interference sensing after extracting the interference signal and reports the sensing result to the control subsystem; the sensing result includes the interference pattern, the jam-to-noise ratio and the available frequency point bitmap;

[0015] The available frequency point bitmap is a binary sequence with M components, which divides the communication frequency band into M intervals at equal intervals, and each interval corresponds to one component, and M is a positive integer; let m = 1, 2, …, M, if the mth component takes the value 0, it means that the mth interval does not exist interference, otherwise the mth interval exists interference; the available frequency point bitmap is used to generate the frequency hopping pattern, and the frequency set corresponding to the frequency hopping pattern will avoid the corresponding interval of the component with value 1 in the available frequency point bitmap, i.e. avoid the frequency band interval with interference.

[0016] Further, the communication state includes the rate profile, the communication bandwidth and the signal-to-noise ratio; the communication bandwidth of the direct spread waveform is the signal bandwidth, while the communication bandwidth of the frequency hopping waveform is the frequency hopping bandwidth;

[0017] The rate profile of the direct spread waveform corresponds to the information rate, the coding efficiency, the modulation order and the spreading ratio, while the rate profile of the frequency hopping waveform corresponds to the information rate, the coding efficiency, the modulation order and the diversity number; the frequency point switching rule of the frequency hopping waveform is determined by the frequency hopping pattern.

[0018] Further, the decision of the direct spread waveform is mainly based on interference suppression, and the specific steps are as follows:

[0019] Step 101, after the control subsystem completes the initialization of the default configuration, periodically receives the communication state and the sensing result from the communication subsystem and the sensing subsystem;

[0020] Step 102, according to the rate grade reported by the communication subsystem and the interference pattern reported by the sensing subsystem, the interference tolerance is converted through table lookup;

[0021] Step 103, according to the rate grade reported by the communication subsystem, the signal-to-noise ratio and the interference-to-noise ratio reported by the sensing subsystem, the interference-to-signal ratio is calculated,

[0022] JSR = JNR - Eb / N0 - 10 x log10(rate x log2(mode)) + 10 x log10(ssr)

[0023] Wherein, Eb / N0 is the signal-to-noise ratio, JNR is the interference-to-noise ratio, JSR is the interference-to-signal ratio, and the units of the three are dB, rate is the coding efficiency, mode is the modulation order, and ssr is the spread spectrum ratio;

[0024] 4) Determine whether the interference-to-signal ratio is less than the interference tolerance: if yes, keep the current rate grade; otherwise, select the rate grade whose interference tolerance is greater than the interference-to-signal ratio;

[0025] 5) Issue the rate grade configuration to the communication subsystem.

[0026] Further, the decision of the frequency hopping waveform is mainly based on interference avoidance and supplemented by interference suppression, and the specific steps are as follows:

[0027] Step 201, after the control subsystem completes the initialization of the default configuration, periodically receives the communication state and the sensing result from the communication subsystem and the sensing subsystem;

[0028] Step 202, according to the rate grade reported by the communication subsystem and the interference pattern reported by the sensing subsystem, the interference tolerance is converted through table lookup;

[0029] Step 203, according to the rate grade reported by the communication subsystem, the communication bandwidth Band and the signal-to-noise ratio, the interference-to-signal ratio is calculated;

[0030] JSR = 10 x log10(Band) - Eb / N0 - 10 x log10(Rb) - 10 x log10(rate x log2(mode)) + 10 x log10(dn),

[0031] Wherein Eb / N0 is signal to noise, JSR is dry signal ratio, both units are dB, Rb is information rate, rate is coding efficiency, mode is modulation order, and dn is diversity number;

[0032] Step 204, it is judged whether the interference pattern is full-band interference, if yes, the available frequency point bitmap is a full 0 sequence, and the frequency hopping pattern is generated;Otherwise, according to the available frequency point bitmap reported by the sensing subsystem, the frequency hopping pattern is generated;

[0033] Step 205, it is judged whether the interference pattern is full-band interference: if yes, when the signal to noise ratio is less than the interference tolerance, the current rate shelf is maintained, when the signal to noise ratio is greater than or equal to the interference tolerance, the rate shelf is adjusted so that the interference tolerance is greater than the signal to noise ratio;Otherwise, the maximum information rate corresponding to the rate shelf is selected;

[0034] Step 206, the rate shelf and the frequency hopping pattern configuration are issued to the communication subsystem.

[0035] Compared with the prior art, the beneficial effects of the present application are:

[0036] Focusing on the typical application scene of communication and sensing integration, combined with the anti-interference waveform physical layer system, the interference signal is effectively separated and extracted in time domain or frequency domain, the coupling degree of communication waveform and interference sensing is enhanced, and the satellite anti-interference communication capability is improved.

[0043] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below combined with embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not used to limit the present application.

[0044] Reference Figure 1The embodiment includes a communication sub-system, a sensing sub-system and a control sub-system.

[0045] The implementation of the communication sub-system is as follows:

[0046] The communication sub-system completes all signal processing functions from service access to service output.

[0047] For the communication sub-system, the direct spread waveform and the frequency hopping waveform adopt a unified frame structure design, data transmission is performed in the form of bursts, and each burst time slot corresponds to a frame. Each frame is composed of three sections, i.e., a pilot section, a data section and a guard section, as shown in FIG. 1. The pilot section contains a synchronization code, a unique word and a mode word, which are used to identify the starting position of the frame, eliminate phase ambiguity and indicate the data section rate, respectively; the data section contains a plurality of coding blocks, which are set to different lengths according to the corresponding information rate; and the guard section does not transmit data, and the frequency point hopping of the frequency hopping waveform is completed in the guard section. Figure 2

[0048] The sending end of the communication sub-system transmits corresponding data frames in the burst time slot according to the set rate and the signaling of the control sub-system. The rate is variable in each burst time slot. The rate of the direct spread waveform corresponds to the information rate, the coding efficiency, the modulation order and the spreading ratio, while the rate of the frequency hopping waveform corresponds to the information rate, the coding efficiency, the modulation order and the diversity number. In addition, the frequency point switching rule of the frequency hopping waveform is determined by the frequency hopping pattern.

[0049] The receiving end of the communication sub-system realizes adaptive reception by analyzing the pilot section information, and simultaneously reports the communication state to the control sub-system. The communication state includes the rate, the communication bandwidth and the signal-to-noise ratio. The communication bandwidth of the direct spread waveform is the signal bandwidth, while the communication bandwidth of the frequency hopping waveform is the frequency hopping bandwidth.

[0050] The burst time slot is T slot =T pre +T data +T suf , where T pre , T data , T suf represent the pilot section, the data section and the guard section time length, respectively. The direct spread waveform considers two rates, which are denoted as G S (1) and G S (2), respectively; the information rate, the coding efficiency, the modulation order and the spreading ratio thereof are Rb(G S (g)), rate(G S (g)), mode(G S (g)) and ssr(G S (g)), respectively, g∈{1,2}; and the interference tolerance of G S (1) is greater than that of G S .(2) The interference tolerance. The frequency hopping waveform also considers two speed levels, which are respectively denoted as G H (1) and G H (2), its information rate, coding efficiency, modulation order and diversity multiplicity are Rb(G H (g))、rate(G H (g))、mode(G H (g)) and dn(G H (g)), g∈{1,2}; G H (1) The interference tolerance is greater than G H (2) Interference tolerance.

[0051] In direct spread spectrum communication, the transmitter initially selects G S (2); When frequency hopping waveform communication is used, the transmitter initially selects G H (2) The receiving end implements adaptive reception by parsing the pilot zone information and reports the communication status to the control subsystem. The communication status includes the rate level, communication bandwidth Band, and signal-to-noise ratio Eb / N0.

[0052] (2) The implementation of the perception subsystem is as follows:

[0053] The perception subsystem completes interference detection and identification.

[0054] For the perception subsystem, the perception bandwidth is consistent with the communication bandwidth. Due to the openness of the satellite channel, the communication signal and the interference signal will be mixed together at the receiving end, so measures must be taken to extract the interference signal.

[0055] When using the DS waveform, combined with its burst characteristics, signal acquisition is completed within the protection period of each time slot, such as Figure 3 As shown, the interference signal can be separated in the time domain.

[0056] When using a frequency hopping waveform, combined with its carrier frequency hopping characteristics, signal acquisition is performed according to the frequency hopping period interval after the frequency switching is completed, such as Figure 4 As shown, the collected signal is transformed into the frequency domain, the power spectrum is calculated and smoothed, and the interference signal can be separated in the frequency domain.

[0057] After extracting the interference signal, the perception subsystem performs interference perception and reports the perception results to the control subsystem. The perception results include the interference pattern, interference-to-noise ratio, and available frequency bitmap. The available frequency bitmap is a binary sequence with M components, which divides the communication frequency band into M equally spaced intervals, with each interval corresponding to one component. If the mth component is 0, then there is no interference in the mth interval; otherwise, there is interference in the mth interval. The available frequency bitmap is used to generate a frequency hopping pattern. The frequency set corresponding to the frequency hopping pattern will avoid the corresponding intervals in the available frequency bitmap where the component is 1.

[0058] Under the DS waveform condition, the sensor collects Node points at a sampling rate of Fs during the protection period of each burst time slot, and the data obtained is a time domain sequence x = (x1,…,x Node ). Under baseband sampling conditions, x is a complex sequence. Fs should satisfy Fs×T suf ≥Node and Fs≥Band, where T suf Represents the protection zone duration. Perform fast Fourier transform on x to obtain the frequency domain sequence X=(X1,…,X Node ), where X n is a complex number, i is an imaginary unit. The power spectrum corresponding to x is S=(S1,…,S Node ),in Establishment

[0059] Under the frequency hopping waveform condition, the sensor collects Node points at a sampling rate of Fs in each hopping period according to the frequency hopping period. The data obtained by sampling the hth hop is the time domain sequence x(h)=(x1(h),…,x Node (h)). Under baseband sampling conditions, x(h) is a complex sequence. Fs should satisfy Fs×T slot ≥Node and Fs≥Band. Perform fast Fourier transform on x(h) to obtain the frequency domain sequence X(h)=(X1(h),…,X Node (h)), where X n (h) is a complex number, i is an imaginary unit. The power spectrum corresponding to x(h) is S(h)=(S1(h),…,S Node (h)), where Establishment The frequency hopping pattern is optimized to ensure that the frequency points of adjacent H hops do not overlap. Take the power spectrum set corresponding to adjacent H hops S(h+1),…,S(h+H)}. Take the median of each component of {S(h+1),…,S(h+H)} to filter out the frequency hopping signal, and get S=(S1,…,S Node ),in Established S n =median{S n(h+1),…,S n (h+H)}.

[0060] The power spectrum S only retains the interference signal related information. By analyzing the power spectrum S, the sensing results such as the interference pattern, the jam-to-noise ratio, and the available frequency point bitmap can be obtained.

[0061] 1) The trained classifier is used to identify the interference type according to the power spectrum S. The classifier input is the power spectrum S, and the output is the interference pattern. The interference pattern supports four types of single tone, multi-tone, partial band, and full band.

[0062] 2) The interference power and the jam-to-noise ratio where PN is the noise power, which can be calibrated in advance.

[0063] 3) A threshold TB is set to binarize the power spectrum S into a binary sequence BS=(BS1,…,BS Node ), that is, when S n >TB, BS n =1, and when S n ≤TB, BS n =0. Each component of BS corresponds to a frequency, and the conversion relationship between the component index n and the frequency freq is freq(n)=f c +(n-Node)*f r , where f r =Fs / Node is the frequency resolution, and f c is the center frequency of the communication bandwidth. When BS n =0, freq(n) does not exist interference; when BS n =1, freq(n) exists interference. The available frequency point bitmap bitmap=(b1,…,b M ) is also a binary sequence, where b m ∈{1,0}. The available frequency point bitmap bitmap divides the communication bandwidth Band into M equal intervals, and b m corresponds to the interval The conversion relationship between bitmap and bs is as follows. If there exists an index n such that and BS n =1 is true, then b m =1; otherwise, b m =0.

[0064] After completing the interference detection and identification, the sensing subsystem reports the sensing results to the control subsystem. The sensing results include the interference pattern, the jam-to-noise ratio JNR, and the available frequency point bitmap bitmap.

[0065] (3) Control subsystem

[0066] The control subsystem formulates corresponding strategies and issues execution according to the communication state and the sensing result.

[0067] For the control subsystem, the anti-interference strategy is divided into interference suppression and interference avoidance. Interference suppression achieves the purpose of anti-interference by adjusting the rate bin. Interference avoidance achieves the purpose of anti-interference by adjusting the frequency hopping pattern.

[0068] The decision of the direct spread waveform is mainly interference suppression, and the flow is as shown in Figure 5 The specific steps are described as follows:

[0069] S101, after the control subsystem completes the initialization of the default configuration, it periodically receives the communication state and the sensing result from the communication subsystem and the sensing subsystem. The communication state is the rate bin G S (2), the communication bandwidth Band, and the signal-to-noise ratio Eb / N0. The sensing result is the interference pattern and the jam-to-noise ratio JNR.

[0070] S102, according to the rate bin G S (2) and the interference pattern, it is converted into the interference margin TJS through table lookup. The relationship between the rate bin, the interference pattern, and the interference margin can be determined in advance.

[0071] S103, according to the rate bin G S (2), the signal-to-noise ratio Eb / N0, and the jam-to-noise ratio JNR, the jam-to-signal ratio JSR is calculated as JSR = JNR - Eb / N0 - 10xlog10(rate(G S (2))xlog2(mode(G S (2))) + 10xlog10(ssr(G S (2)).

[0072] S104, it is judged whether the jam-to-signal ratio JSR is less than the interference margin TJS: if yes, the current rate bin G S (2) is maintained; otherwise, the rate bin G S (1) is selected.

[0073] S105, the rate bin configuration is issued.

[0074] The decision of the frequency hopping waveform is mainly interference avoidance, supplemented by interference suppression. The flow is as shown in Figure 6 The specific steps are described as follows.

[0075] S201, after the control subsystem completes the initialization of the default configuration, it periodically receives the communication state and the sensing result from the communication subsystem and the sensing subsystem. The communication state is the rate bin G H(2) Signal-to-noise ratio Eb / N0. The sensing result is an interference pattern, a jam-to-noise ratio JNR, and a bitmap of available frequency points.

[0076] S202, according to the rate grade G H (2) and the interference pattern, the jamming margin TJH is converted by table lookup. The relationship between the rate grade, the interference pattern, and the jamming margin can be determined in advance.

[0077] S203, according to the rate grade G H (2), the communication bandwidth Band and the signal-to-noise ratio Eb / N0, the jam-to-signal ratio JSR is calculated

[0078] JSR=10*log10(Band)-Eb / N0-10*log10(Rb(G H (2))-10*log10(rate(G H (2))*log2(mode(G H (2))+10*log10(dn(G H (2)).

[0079] S204, if the interference pattern is full-band interference, the bitmap of available frequency points is a full 0 sequence, and a frequency hopping pattern is generated; if the interference pattern is single-tone, multi-tone or partial-band interference, a frequency hopping pattern is generated according to the bitmap of available frequency points bitmap reported by the sensing subsystem;

[0080] S205, if the interference pattern is full-band interference, when the jam-to-signal ratio JSR is less than the jamming margin TJH, the current rate grade G H (2) is maintained, and when the jam-to-signal ratio JSR is greater than or equal to the jamming margin TJH, the rate grade G H (1) is selected; if the interference pattern is single-tone, multi-tone or partial-band interference, the rate grade G H (2) is selected.

[0081] S206, the rate grade and the frequency hopping pattern configuration are issued.

[0082] In summary, the embodiment adopts a communication and sensing integrated architecture, combines an anti-jamming waveform physical layer system, effectively realizes separation and extraction of interference signals in time domain or frequency domain, and realizes improvement of satellite anti-jamming communication capability.

[0083] It should be noted that the above only describes the preferred application examples of the present application, and is not used to limit the protection scope of the present application. Any technical solution with equivalent substitution or equivalent transformation is within the protection scope of the present application.
