DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] At present, external high-gain antennas improve signal strength by increasing the area for receiving and transmitting signals, but this method is inconvenient to carry and has high requirements for installation location. Signal amplifiers improve communication quality by amplifying weak received signals, but they may introduce additional noise, resulting in unstable signal quality.

[0038] Based on the above problems, the present invention provides a satellite signal enhancement device, which can remove the interference noise introduced by the signal amplifier without the need for an additional external high-gain antenna, thereby improving the stability, accuracy and strength of the satellite mobile phone direct connection signal.

[0039] Combine the following Figure 1-Figure 5 The satellite signal enhancement device of the present invention is described. The satellite signal enhancement device provided by the present invention can be applied to the enhancement of the signal connecting any terminal with a satellite, including but not limited to mobile phones, vehicle-mounted terminals, satellite communication terminals, etc.

[0040] Figure 1 FIG. 1 is one of the structural schematic diagrams of the satellite signal enhancement device provided by the present invention. Figure 1 As shown, the satellite signal enhancement device 100 includes: a signal receiving module 110, a signal processing module 120 and a signal transmitting module 130, wherein:

[0041] The signal receiving module 110 is connected to the signal processing module 120, and the signal processing module 120 is connected to the signal transmitting module 130;

[0042] The signal receiving module 110 is used to amplify the strength of the initial signal sent by the satellite based on the relative position information between the satellite and the signal receiving module 110 to obtain a second signal;

[0043] The signal processing module 120 is used to enhance the information of the second signal to obtain a valid signal;

[0044] The signal transmitting module 130 is used to amplify the strength of the effective signal to obtain a target signal, and send the target signal to the satellite.

[0045] It should be noted that the satellite signal enhancement device 100 can be installed in any terminal that needs to communicate with a satellite, such as a satellite phone.

[0046] It should be noted that, in addition to amplifying the strength of the initial signal sent by the satellite, the signal receiving module 110 can also receive the initial signal transmitted by the satellite.

[0047] It should be noted that the terminal installed with the satellite signal enhancement device 100 can receive the initial signal sent by the satellite only after it is started.

[0048] Here, the satellite may be any suitable type of satellite, such as a low-orbit satellite, a medium-orbit satellite, a high-orbit satellite, etc.

[0049] Here, the strength of the initial signal is a parameter that measures the power level of the satellite signal received by the terminal. It is usually expressed by gain, and the unit of gain is decibel milliwatt (dBm). The gain reflects the ratio between the signal power received by the terminal and the reference power. The higher the gain, the better the received signal strength; the lower the gain, the worse the received signal strength.

[0050] Here, the relative position between the satellite and the signal receiving module 110 may be the relative position between the satellite and the terminal, or the relative position between the satellite and the satellite signal enhancement device 100. The relative position may include an azimuth angle, a phase angle, a distance, and the like.

[0051] It should be noted that the relative position between the terminal and the satellite will change when the terminal or the satellite moves. Therefore, the amplification factor of the initial signal strength by the signal receiving module 110 needs to be continuously adjusted according to the change in relative position.

[0052] Here, the enhancement processing may include filtering processing, extraction processing, and the like.

[0053] Here, a valid signal refers to a signal that contains only accurate information. For example, if the useful information output by user A is "one, two, three", user B will add descriptions during the transmission process and obtain a signal containing other information. Therefore, the signal needs to be enhanced to obtain a valid signal that only contains the useful information "one, two, three".

[0054] It should be noted that the initial signal sent by the satellite may introduce interference noise during the transmission or amplification process, resulting in inaccurate signals. Therefore, the signal needs to be enhanced to obtain a valid signal.

[0055] In an embodiment of the present invention, the signal receiving module 110 amplifies the strength of the initial signal sent by the satellite according to the relative position information between the satellite and the signal receiving module 110 to obtain an amplified signal, thereby improving the strength and accuracy of the signal; then, the signal processing module 120 is used to enhance the amplified signal to obtain a valid signal, remove the interference noise introduced by the signal amplifier, and improve the accuracy and stability of the signal; finally, the signal transmitting module 130 is used to amplify the strength of the valid signal to obtain the target signal, thereby further improving the strength of the valid signal. In this way, the satellite signal enhancement device 100 provided by the present invention can remove the interference noise introduced by the signal amplifier without the need to add an additional external high-gain antenna, thereby improving the stability, accuracy and strength of the satellite mobile phone direct connection signal.

[0056] Figure 2 FIG. 2 is a second structural diagram of the satellite signal enhancement device provided by the present invention. Figure 2 As shown, the signal receiving module 110 includes: a receiving antenna 111 and a preamplifier 112; the relative position information includes: the elevation angle of the satellite relative to the receiving antenna 111 and the azimuth angle of the satellite relative to the receiving antenna 111, wherein:

[0057] The receiving antenna 111 is connected to the preamplifier 112, and the preamplifier 112 is connected to the signal processing module 120;

[0058] The receiving antenna 111 is used to receive the initial signal;

[0059] The preamplifier 112 is used to determine a first amplification value based on the pitch angle and the azimuth angle; determine the gain of the receiving antenna 111; and amplify the strength of the initial signal based on the gain of the receiving antenna 111 and the first amplification value to obtain the second signal.

[0060] In the embodiment of the present invention, after receiving the initial signal transmitted by the satellite, the receiving antenna 111 inputs the initial signal to the preamplifier 112 to amplify the strength of the initial signal to obtain a second signal.

[0061] Here, the first amplification value refers to the value after the initial amplification of the strength of the initial signal, using the pitch angle, azimuth angle and amplification function Calculate the first magnification value, where To enlarge the parameters passed by the function, represents the pitch angle, Indicates the azimuth.

[0062] Here, the gain of the receiving antenna 111 refers to the ratio of the power density of the signal generated by the actual antenna and the ideal radiating unit (such as a point source antenna) at the same point in space under the condition of equal input power. The higher the gain, the better the radiation effect of the receiving antenna 111 in this direction.

[0063] It should be noted that the strength of the second signal can be the first product, which can be the product of the first amplification value, the gain of the receiving antenna 111 and the strength of the initial signal, or it can be the product of the weighted first amplification value, the weighted gain of the receiving antenna 111 and the weighted strength of the initial signal.

[0064] Exemplarily, the strength of the second signal is calculated according to the following formula (1):

[0065] (1)

[0066] in, is the strength of the second signal (i.e., the output power of the preamplifier 112), is the strength of the initial signal (i.e., input power), is the gain of receiving antenna 111, is the first magnification value.

[0067] It should be noted that the receiving antenna 111 adopts a wide-beam antenna, which can receive satellite signals within a larger angle range, greatly improving the adaptability of the satellite phone to changes in satellite position.

[0068] It should be noted that the gain of the preamplifier 112 is dynamically adjusted according to the real-time position of the satellite. When the satellite is at a low elevation angle, the signal propagation path becomes longer and the attenuation becomes more serious. At this time, the gain of the preamplifier 112 will be significantly increased to compensate for the signal attenuation.

[0069] In another embodiment, the operating frequency range and gain characteristics of the preamplifier are carefully adjusted according to the characteristics of different satellite frequency bands and communication protocols. For satellite signals operating in the high frequency band, the bandwidth of the preamplifier is appropriately widened to ensure effective reception of high frequency signals; and for communication protocols with weak signal strength, the gain of the preamplifier is further increased to enhance the reception effect.

[0070] In an embodiment of the present invention, the amplification factor of the preamplifier 112 is dynamically adjusted in real time according to the elevation angle and azimuth angle of the satellite and the receiving antenna 111. Compared with an amplifier with a fixed amplification factor, the signal strength is improved while ensuring the real-time nature of the signal and the accuracy of transmission.

[0071] Figure 3 This is the third structural diagram of the satellite signal enhancement device provided by the present invention. Figure 3 As shown, the enhancement processing includes filtering processing and analyzing processing, and the signal processing module 120 includes: a filtering unit 121 and a digital signal processing unit 122, wherein:

[0072] The filtering unit 121 is respectively connected to the signal receiving module 110 and the digital signal processing unit 122, and the digital signal processing unit 122 is connected to the signal transmitting module 130;

[0073] The filtering unit 121 is used to filter the information of the second signal to obtain a fourth signal;

[0074] The digital signal processing unit 122 is used to analyze and process the fourth signal to obtain the valid signal.

[0075] Here, the function of the filtering unit 121 is to remove out-of-band noise, wherein the filtering unit 121 may be any suitable filter, such as a bandpass filter, a bandstop filter, a notch filter, a filter formed by combining a low-pass filter and a high-pass filter, and the like.

[0076] Exemplarily, the filtering unit 121 adopts a high-performance bandpass filter, whose bandwidth and center frequency are carefully designed to accurately remove out-of-band noise while retaining useful signals to the greatest extent.

[0077] Here, the function of the digital signal processing unit 122 is to perform analysis processing on the fourth signal, wherein the analysis processing may include demodulation processing, decoding processing, etc.

[0078] It should be noted that in order to ensure data security and data transmission rate during the transmission process of satellite signals, the signals need to be modulated and encoded before transmission. Therefore, the signal received by the receiving antenna 111 is a modulated and encoded signal. At this time, the signal needs to be decoded and demodulated.

[0079] In an embodiment of the present invention, the signal receiving module 110 transmits the second signal to the filtering unit 121, and the filtering unit 121 filters the second signal to obtain a fourth signal; the filtering unit 121 transmits the fourth signal to the digital signal processing unit 122, and the digital signal processing unit 122 analyzes (such as demodulates, decodes) the fourth signal to obtain a valid signal.

[0080] In the embodiment of the present invention, the amplified signal is filtered and analyzed by the filtering unit 121 and the digital signal processing unit 122 to remove out-of-band filtering, retain useful signals to the greatest extent, and improve the accuracy of the data. At the same time, the data is analyzed and processed to restore the signal and improve the quality of the satellite signal.

[0081] Further, the analysis process includes demodulation processing and extraction, and the digital signal processing unit 122 includes: a demodulation subunit and an extraction model, wherein:

[0082] The demodulation subunit is respectively connected to the filtering unit 121 and the extraction model, and the extraction model is connected to the signal transmission module 130;

[0083] The demodulation subunit is used to demodulate the fourth signal to obtain a digital signal;

[0084] The extraction model is used to extract the effective signal from the digital signal based on the characteristics of the digital signal; the extraction model is trained based on the time domain characteristics, frequency domain characteristics and phase characteristics of the sample signal.

[0085] Here, the demodulation subunit modulates the received analog signal into a digital signal, and the demodulated signal will contain the original binary information, such as time domain information, frequency domain information, phase information, etc. The demodulation subunit can use any suitable demodulation algorithm, such as binary phase shift keying (BPSK), amplitude shift keying demodulation, frequency shift keying demodulation, four-phase phase shift keying, etc.

[0086] Exemplarily, the demodulation algorithm used by the demodulation subunit is BPSK demodulation. Assuming that the fourth signal is , then the demodulated signal The calculation is as follows formula (2):

[0087] (2)

[0088] in, The reference signal used for coherent demodulation that is in phase with the carrier signal is: is the carrier frequency, is the phase shift, It's time.

[0089] Then, the high-frequency components are removed by a low-pass filter, and the resulting baseband signal can be expressed as follows:

[0090] (3)

[0091] in, is the signal amplitude, is the original binary data (value is ±1), It's noise.

[0092] Here, the extraction model can extract useful information from the signal, wherein the extraction model can be any suitable model, such as a convolutional neural network (CNN), a recurrent neural network (RNN),

[0093] Here, the extraction model may be pre-trained using sample signals or downloaded from a server.

[0094] Exemplarily, the training steps of the extraction model include: using the traditional BPSK demodulation algorithm to demodulate the received signal into a digital signal, and the demodulated signal will contain the original binary information; extracting features from the demodulated signal to obtain a vector representation that can represent the signal features, which may include time domain features, frequency domain features, and phase features; inputting the features of each BPSK signal (such as time domain features, frequency domain features, phase features) and the corresponding information labels into the initial model to obtain prediction information; determining the loss information based on the prediction information and the information label, and continuously optimizing the parameters through the loss information to learn the mapping relationship between the signal and the information until the loss information converges to obtain the extraction model. After the extraction model is trained, the BPSK signal is input into the extraction model, and the useful information corresponding to the signal is directly output to achieve end-to-end prediction.

[0095] In the embodiment of the present invention, a suitable demodulation algorithm is used to demodulate the fourth signal to obtain original binary information, and the original binary information is input into the extraction model to directly extract the corresponding valid signal of the signal.

[0096] In another embodiment, adaptive filtering technology can be applied before or after the extraction module. Adaptive filtering can monitor the distortion during signal transmission in real time and automatically adjust the equalization parameters to compensate for the amplitude and phase of the signal, thereby effectively reducing the impact of factors such as multipath propagation and frequency selective fading on signal quality, so as to better adapt to different signal environments and further enhance signal quality and extraction accuracy.

[0097] In the embodiment of the present invention, the demodulation subunit demodulates the signal to improve the accuracy of signal demodulation; then, the extraction model is used to extract useful information from the demodulated signal, and end-to-end is achieved, which improves the speed of extracting the signal, thereby improving the rate of signal transmission. At the same time, the extraction model can adjust parameters through autonomous learning to improve the accuracy of the signal.

[0098] Figure 4 FIG. 4 is a schematic diagram of the structure of the satellite signal enhancement device provided by the present invention. Figure 4 As shown, the signal processing module 120 further includes: a gain control unit 123, wherein:

[0099] The gain control unit 123 is connected to the digital signal processing unit 122 and the signal transmitting module 130 respectively;

[0100] The gain control unit 123 is used to determine the gain of the strength of the effective signal based on the strength of the effective signal.

[0101] Here, the gain of the strength of the effective signal may be understood as the amplification factor of the second amplifier in the transmitting module.

[0102] It should be noted that the gain control unit 123 only determines the gain in the second amplifier in the transmitting module, and does not amplify the signal. Here, the gain control unit 123 determines a higher gain when the strength of the effective signal is low, and determines a lower gain when the strength of the effective signal is high.

[0103] Here, the gain adjustment coefficient of the gain control unit 123 can be calculated by the following formula (4):

[0104] (4)

[0105] in, is the input signal (i.e. the above-mentioned effective signal) strength, is the reference signal strength, is the adjustment factor, where Can be pre-set.

[0106] In the embodiment of the present invention, after the digital signal processing unit 122 outputs the valid signal, the gain control unit 123 determines the gain of the strength of the valid signal according to the strength of the valid signal.

[0107] In the embodiment of the present invention, the gain control unit 123 monitors the strength of the effective signal in real time and keenly, and quickly calculates the adjustment coefficient, thereby achieving dynamic and precise adjustment of the gain, thereby improving the accuracy and strength of the signal.

[0108] Figure 5 FIG. 5 is a structural schematic diagram of the satellite signal enhancement device provided by the present invention. Figure 5 As shown, the signal transmission module 130 includes: a second amplifier 131 and a transmitting antenna 132, wherein:

[0109] The second amplifier is connected to the gain control unit 123, the digital signal processing unit 122 and the transmitting antenna;

[0110] The second amplifier is used to amplify the strength of the effective signal based on the gain of the strength of the effective signal to obtain the target signal;

[0111] The transmitting antenna is used to send the target signal to the satellite.

[0112] Exemplarily, the intensity of the target signal is calculated as follows:

[0113] (5)

[0114] in, is the input power (i.e. the strength of the effective signal), is the gain of the second amplifier, where With the above gain adjustment factor The second amplifier may be a linear amplifier.

[0115] It should be noted that the transmitting antenna is a directional antenna. Through precise beamforming technology, the transmitted signal is concentrated in the direction of the satellite, which significantly improves the signal transmission efficiency and transmission distance.

[0116] In the embodiment of the present invention, after the digital signal processing unit 122 outputs the valid signal, the second amplifier amplifies the strength of the valid signal to obtain the target signal, and the transmitting antenna sends the target signal to the satellite. Before amplifying the strength of the valid signal, the second amplifier can modulate and encode the valid signal to facilitate subsequent signal transmission and ensure the security and rate of signal transmission.

[0117] In the embodiment of the present invention, the second amplifier of the signal transmission module 130 can adopt a high-efficiency linear amplifier, which can provide sufficiently powerful and stable transmission power while ensuring the linearity of the signal, and ensure that the signal has enough energy to overcome various attenuation and interference during the transmission process. The transmitting antenna adopts a highly directional directional antenna, and through precise beamforming technology, the transmission signal is concentrated in the direction of the satellite, which significantly improves the transmission efficiency and transmission distance of the signal.

[0118] In another embodiment of the present invention, by adopting low-power chips and intelligent power management technology, the energy consumption of the satellite signal enhancement device can be significantly reduced without affecting the signal enhancement performance, thereby extending the life of the satellite terminal. At the same time, the heat dissipation design of the satellite signal enhancement device can be improved to ensure that the system can still operate stably under long-term high-power working conditions without performance degradation or failure due to overheating.

[0119] Through the continuous optimization of satellite signal enhancement devices, the communication performance of satellite terminals directly connected to satellites has been significantly improved. Whether in remote areas with weak signal strength or in complex and changeable electromagnetic environments, it can provide users with clear, stable, and high-speed satellite communication services to meet users' communication needs in special scenarios such as emergency rescue, field exploration, and ocean voyages.

[0120] The present invention can significantly improve the signal strength and stability of a satellite terminal directly connected to a satellite, improve the communication quality, and provide users with more reliable satellite communication services by optimizing the signal receiving module, signal processing module and signal transmitting module and combining accurate gain control and signal processing algorithms.

[0121] The satellite signal enhancement method provided by the present invention is described below. The satellite signal enhancement method described below and the satellite signal enhancement device 100 described above can correspond to each other.

[0122] Figure 6 FIG. 1 is a flow chart of the satellite signal enhancement method provided by the present invention. Figure 6 As shown, the satellite signal enhancement method is applied to a satellite signal enhancement device, and the satellite signal enhancement method includes:

In this way, without the need to add an additional external high-gain antenna, the interference noise introduced by the signal amplifier can also be removed, thereby improving the stability, accuracy and strength of the satellite mobile phone direct connection signal.
