Due to the existence of communication signals in different frequency bands, the coordination and compatibility between long-distance communication signals in different frequency bands are becoming more difficult.

However, since it only coordinates the output order of the signal sources, it fails to solve the compatibility problem of the signal sources and has certain limitations. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides a multi-frequency signal spectrum compatibility method and system based on remote communication, which has the advantages of real-time, accuracy, and high compatibility, and solves the problem of coordination and compatibility between remote communication signals in different frequency bands.

[0006] (2) Technical solution

[0007] In order to solve the technical problem of difficult coordination and compatibility between telecommunication signals in different frequency bands, the present invention provides the following technical solutions:

[0008] This embodiment discloses a multi-frequency signal spectrum compatibility method based on remote communication, which specifically includes the following steps:

[0009] S1. Establishing a remote communication connection through a dynamic communication connection to receive multi-frequency communication signals in real time, and constructing a sample set based on the multi-frequency communication signals received in real time;

[0010] S2. Processing the multi-frequency communication signal in the sample set to obtain a processed multi-frequency communication signal;

[0011] S3. Analyze the processed multi-frequency communication signal to determine the communication signal type of each frequency band in the multi-frequency communication signal;

[0012] S4. Modulate the communication signals of each frequency band in the determined multi-frequency communication signal to be compatible through a signal modulation method.

[0013] The present invention establishes a remote communication connection through a dynamic communication connection mode to receive multi-frequency communication signals in real time, and constructs a sample set based on the multi-frequency communication signals received in real time. At the same time, the multi-frequency communication signals in the sample set are processed, and the processed multi-frequency communication signals are analyzed to determine the communication signal type of each frequency band in the multi-frequency communication signal. Finally, the communication signals of each frequency band in the determined multi-frequency communication signal are modulated and compatible through a signal modulation mode, thereby improving the real-time compatibility and compatibility of the multi-frequency signal spectrum.

[0014] Preferably, establishing a remote communication connection in a dynamic communication connection manner to receive multi-frequency communication signals in real time comprises the following steps:

[0015] S11. Allocate an IP address to each user through the cloud server;

[0016] When users need to communicate, they will apply to the surrounding cloud server nodes;

[0017] After receiving the user's communication application, each cloud server will assign an IP address to the user;

[0018] After receiving the IP addresses assigned by each cloud server, the user will select the first IP address received and provide feedback to the cloud server corresponding to the IP address;

[0019] S12. The user communicates with other users based on the allocated IP.

[0020] Preferably, the user communicating with other users based on the assigned IP includes the following steps:

[0021] S121. User 1 sends a connection request to user 2 based on the IP address of user 2, and specifies the initial sequence number seq1 of the connection request;

[0022] When user 1 sends a connection request to user 2, the synchronization bit SYN of user 1 is set to 1, the initial sequence number seq1 is set to x, and the connection request with SYN=1 cannot carry data, consuming a sequence number;

[0023] S122. After receiving the connection request from user 1, user 2 will feedback the connection request to user 1, setting the initial sequence number seq2 of the feedback connection request to y. At the same time, it will use user 1's sequence number + 1 as the confirmation value to indicate that it has received user 1's connection request.

[0024] S123. After receiving the feedback connection request from user 2, user 1 sends a confirmation request with user 2's sequence number + 1 as the confirmation value, indicating that the feedback connection request from user 2 has been received. At this point, the two parties have established a connection.

[0025] The present invention uses a dynamic IP address allocation method and an IP address-based connection establishment method, determines the IP address through IP application and dynamic selection based on feedback time, and simultaneously establishes a remote communication connection and receives multi-frequency communication signals in real time based on a multi-layer communication request method based on the determined IP address, thereby ensuring the real-time and security of the remote communication connection establishment.

[0026] Preferably, the processing of the multi-frequency communication signal in the sample set to obtain the processed multi-frequency communication signal comprises the following steps:

[0027] S21, performing noise reduction processing on the multi-frequency communication signal in the sample set to obtain a noise-reduced multi-frequency communication signal;

[0028] S22. Decomposing the noise-reduced multi-frequency communication signal by Fourier decomposition based on the noise-reduced multi-frequency communication signal;

[0029] S23: Set the decomposed multi-frequency communication signal as the processed multi-frequency communication signal.

[0030] Preferably, performing noise reduction processing on the multi-frequency communication signals in the sample set comprises the following steps:

[0034]

[0035] Where y(n) represents the data of the nth sampling point after smoothing, x(n) represents the data of the nth sampling point, and n represents the number of sampling points;

[0036] The multi-frequency communication signal is adjusted based on the smoothed data to obtain a noise-reduced multi-frequency communication signal.

[0037] Preferably, decomposing the noise-reduced multi-frequency communication signal by Fourier decomposition comprises the following steps:

[0041] Based on the angular frequency components and periodic variation rules, Y(t) is decomposed and reconstructed. The decomposed and reconstructed Y(t) is as follows:

[0042] Y(t)=D(t)+F(t)+L(t);

[0043] Wherein, D(t) is the periodic component at time t, F(t) is the high-frequency component at time t, and L(t) is the low-frequency component at time t.

[0044] The present invention calculates the data collected at each sampling point in the window by setting a window and using a smoothing processing formula to complete the noise reduction processing of the multi-frequency communication signal in the sample set. At the same time, the noise-reduced multi-frequency communication signal is decomposed and reconstructed by Fourier decomposition, thereby realizing the processing of each component of the multi-frequency communication signal, avoiding interference from other components, and improving the reliability of the multi-frequency signal spectrum processing.
