Description

Technical Field

[0001] The present invention belongs to the field of communication technology, and in particular relates to a signal enhancement method and system based on Beidou 5G fusion. Background Art

[0002] With the rapid development of the marine economy, offshore operations are expanding, and offshore distances are increasing. Traditional land-based base stations are unable to cover distant seas, leading to problems such as unstable signals and insufficient bandwidth for maritime communication equipment. This is especially true when a vessel is in a dynamic environment, where the swaying of the hull can cause shifts in antenna position and orientation, exacerbating fluctuations in communication quality.

[0003] Currently, improving the maritime communication environment primarily relies on increasing the number of base stations or boosting transmission power. However, these approaches are difficult to implement in remote areas and may negatively impact marine ecosystems. Furthermore, existing 5G communication technologies lack effective signal enhancement or compensation mechanisms for dynamic ship hull rolling, resulting in unstable network connections and a poor user experience.

[0004] Ultra-long-distance 5G communications typically use the 700MHz low-band 5G NR network, which performs best at the center frequency of the Bandwidth Part (BWP). However, the dynamic motion of ships operating at sea (such as violent shaking and tilting) can cause periodic changes in the position and orientation of the antenna. Defined by phase Here, ω0 is the angular velocity, ω0 = 2πf0. It can be seen that the rotational angular velocity generated by the periodic rolling of the ship causes changes in the antenna phase. Furthermore, when the ship is rolling, changes in antenna position can lead to fluctuations in signal strength, beam direction deviations, and frequent cell ID switching, which in turn reduces network connection stability and data transmission efficiency, ultimately affecting the quality of 5G communication signals. Therefore, a 5G communication terminal signal enhancement method that can adapt to complex maritime environments is urgently needed to improve the quality of 5G communications in the open sea and ensure the stability of network connections.

[0005] Chinese patent publication number CN119355758A discloses a hierarchical control system and method for satellite navigation signals based on time division multiplexing, including the following steps: S1, signal source selection: selecting satellite navigation signal sources to form a signal source set; S2, time allocation: allocating time for the selected signal sources; S3, signal enhancement based on multimodal data fusion: performing signal enhancement based on a multimodal data fusion algorithm; S4, signal quality assessment: performing real-time quality assessment on the enhanced signal; S5, signal retransmission optimization: analyzing the packet loss rate and delay in signal transmission, and based on the analysis results, intelligently selecting signal sources for retransmission, and optimizing the timing and frequency of retransmission. The method described in this invention optimizes signal quality through means such as time division multiplexing and multimodal data fusion. However, in dynamic environments, especially in multipath propagation or environments with strong signal interference, the location and propagation conditions of the signal source may change. This method lacks an adaptive beamforming algorithm to dynamically adjust the weight vector of the antenna array, which will receive more noise or interference signals, causing signal interference problems and efficiency loss. Summary of the Invention

[0006] The purpose of the present invention is to provide a signal enhancement method and system based on Beidou 5G fusion to solve the problems of the existing 5G communication technology lacking an effective signal enhancement mechanism when dealing with dynamic hull shaking, resulting in unstable network connection and poor user experience.

BRIEF DESCRIPTION OF THE DRAWINGS

[0055] Figure 1It is an overall flow chart of the signal enhancement method based on Beidou 5G fusion described in the present invention. DETAILED DESCRIPTION

[0056] In order to make the objectives, technical solutions and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in combination with specific embodiments of the present application and with reference to the accompanying drawings.

[0057] Example 1

[0058] This embodiment provides a signal enhancement method based on BeiDou 5G fusion to improve the quality of ship receiving signals and maintain network stability, achieving signal enhancement in dynamic environments. Figure 1 As shown, the following steps are included:

[0059] The real-time latitude and longitude coordinate information and timestamp of the ship are obtained through the Beidou positioning module.

[0060] The velocity vector of the vessel is calculated based on the acquired real-time latitude and longitude coordinate information to evaluate the motion state of the vessel including the swing amplitude and swing frequency.

[0061] As a preferred implementation of this embodiment, the speed vector of the vessel is calculated based on the acquired real-time latitude and longitude coordinate information as follows:

[0062] For any two consecutive time points t p , t p+1 , Convert the acquired real-time latitude and longitude coordinate information into position vectors in a three-dimensional Cartesian coordinate system The conversion formula is specifically:

[0063] x=R·cos(lat)·cos(lng)

[0064] y=R·cos(lat)·sin(lng)

[0065] z=R·sin(lat)

[0066] Where (x, y, z) is the position vector in the three-dimensional Cartesian coordinate system; lat is the latitude; lng is the longitude; and R is the average radius of the Earth (about 6371 km).

[0067] The relative displacement vector of the vessel is calculated based on the position vector. The calculation formula of the relative displacement vector is specifically as follows:

[0068]

[0069] Where Δx, Δy, and Δz are the relative displacements of the position vector on the x-axis, y-axis, and z-axis, respectively.

[0070] The velocity vector of the ship is calculated by the relative displacement vector of the ship as follows:

[0071]

[0072] Where, is the velocity vector of the ship; Δt=t p+1 -t p .

[0073] As a preferred implementation of this embodiment, the motion state of the vessel including the swing amplitude and the swing frequency is evaluated as follows:

[0074] For any three consecutive time points t p , t p+1 , t p+2 , Calculate the velocity vector of the corresponding ship respectively

[0075] velocity vector of the passing vessel The calculation of the ship's swing amplitude is as follows:

[0076]

[0077] Where A is the swing amplitude of the ship; || is the modulus value.

[0078] The swing frequency is calculated using the average time interval as follows:

[0079]

[0080] Where f is the ship's swing frequency; N is the number of sampled ship motion cycles; T i is the duration of the i-th ship motion cycle, where i = 1, 2, …, n. A motion cycle is the time required for a ship to complete a complete rolling, pitching, or up-and-down motion (e.g., a wave cycle). A motion cycle is the time interval from one peak to the next.

[0081] The beam pointing angle of the antenna array element of the Beidou 5G integrated communication equipment of the ship is determined according to the motion state of the ship, and the weight of the antenna array element is derived through the beam pointing angle to obtain the weight vector of the antenna array.

[0082] As a preferred implementation of this embodiment, the beam pointing angle of the antenna array element of the Beidou 5G converged communication device of the ship is calculated based on the motion state of the ship. This allows the ship's antenna to adjust its pointing angle in real time to compensate for the ship's motion when the ship is constantly swaying. It can be expressed as:

[0083] θ k =αAsin(2πft+φ)

[0084] Where θ k is the beam pointing angle of the kth antenna element; α is the proportional coefficient, which is a coefficient related to the system response. In order to improve the adaptability, a feedback control mechanism is introduced, that is, the quality of the communication signal (the ship receiving signal strength P) is continuously monitored through the closed-loop control system. rx ). And according to the actual effect, α is continuously adjusted in the feedback control mechanism so that the beam pointing angle of the antenna array element is θ k It is approximately synchronized with the change in the ship's swing angle to compensate for the movement of the hull and optimize the communication signal quality. A is the swing amplitude of the ship; t is time; f is the swing frequency; and φ is the initial phase angle.

[0085] As a preferred implementation of this embodiment, the weights of the antenna elements are calculated by the beam pointing angle to obtain the weight vector of the antenna array:

[0086]

[0087] Where w k is the weight of the kth antenna element in the antenna array, w k ∈W, W is the weight vector of the antenna array; j is the imaginary unit; f k_d is the frequency of the target direction of the kth antenna array element; d is the spacing between antenna array elements; θ k is the beam pointing angle of the kth antenna element; M is the total number of antenna elements, k = 1, 2, ..., M, and the total number of antenna elements M must satisfy at least two independent elements 2T2R; f k is the frequency in the direction of the kth antenna element.

[0088] Furthermore, to meet the needs of long-distance 5G communication at sea, a 700MHz band 5G network is usually used, where the wavelength λ of the 700MHz band is:

[0089]

[0090] To ensure beamforming performance, avoid grating lobes interfering with main lobe performance, and reduce mutual coupling, the antenna element spacing d is usually designed to be half a wavelength, that is:

[0091]

[0092] This embodiment uses a multi-antenna configuration to improve communication quality and anti-interference capabilities. When the ship's rolling motion causes the antenna position to change, the beam pointing angle θ of the antenna array is dynamically adjusted based on the ship's (antenna's) motion model to ensure the beam is pointed in the target direction. The beamforming weight vector W is further dynamically adjusted to avoid beam direction deviation, reduce signal strength fluctuations, and mitigate the "ping-pong effect" caused by unstable network signals and frequent cell ID switching due to rolling motion, thereby improving network connection stability and data transmission efficiency.

[0093] Using the adaptive beamforming algorithm, the weight vector of the antenna array is dynamically adjusted to optimize the received signal strength of the ship's Beidou 5G integrated communication equipment.

[0094] As a preferred implementation of this embodiment, the objective function of the adaptive algorithm is defined as:

[0095] P rx =W H GW

[0096] Where, P rx The signal strength received by the ship is obtained by capturing radio signals. In practical applications, it can be measured and obtained through a 5G communication module. The command to query the 5G network signal quality is usually AT+CESQ. For example, if the FM650 Fibercom 5G communication module equipped with the Unisoc V510 chip is used, AT+CESQ is used to obtain the signal strength (including the SINR approximation); G is the channel response matrix; W is the weight vector of the antenna array; W H is the conjugate transpose of W.

[0097] Furthermore, the base station transmitter with 5G signal coverage in the sea area sends a known training sequence. The receiving end of the BeiDou 5G integrated communication equipment on the ship uses the received signal and training sequence to calculate the channel response matrix G through the least squares method, compressed sensing and other methods. Specifically, it is:

[0098] To estimate the channel response matrix G, the transmitter of the 5G signal coverage base station in the sea area sends a known training sequence (also known as a pilot signal). These training sequences are usually carefully designed signals with good correlation, such as pilot symbols in orthogonal frequency division multiplexing (OFDM), pseudo-random sequences (such as Gold sequence or M sequence), etc.

[0099] The training sequence is expressed as:

[0100] x train =[x1,x2,…,x R ] T

[0101] Where x trainis the training sequence; R is the number of transmitting antennas, r=1,2,…,R.

[0102] The signal received by the receiving end of the ship's Beidou 5G converged communication equipment is the superposition of the transmitted signals after passing through the channel, and also contains noise and interference. Assuming that the receiving end of the ship's Beidou 5G converged communication equipment has S antennas, the signal received by the sth receiving antenna is:

[0103]

[0104] Where y s is the signal vector received by the sth receiving antenna; s=1,2,…,S; G s,r is the channel response from the rth transmitting antenna to the sth receiving antenna; z s is the noise and interference of the sth receiving antenna.

[0105] If all received signals are expressed in matrix form, the signal vector received by the receiver is:

[0106] y=Gx train +z

[0107] Where y is the received signal vector; G is the S×R channel response matrix; and z is the noise and interference of the receiving antenna.

[0108] If the channel is sparse (for example, only a small number of paths have a significant impact on signal transmission), compressed sensing techniques can be used to estimate G.

[0109]

[0110] Where τ is the regularization parameter, which is used to balance the data fitting term and sparsity, and can be obtained through cross-validation, heuristic rules, Bayesian and other methods; ‖‖1 is the L1 norm.

[0111] In practical applications, the channel is time-varying (e.g., in mobile communications). Therefore, the receiver needs to periodically send a new training sequence and re-estimate G to maintain beamforming accuracy.

[0112] As a preferred implementation of this embodiment, based on the motion state of the vessel, combined with an adaptive beamforming algorithm, the beamforming weight vector is dynamically adjusted to reduce signal strength fluctuations, avoiding the "ping-pong effect" caused by shaking, which leads to unstable signal reception and frequent switching of the vessel's cell ID, thereby reducing network connection stability and data transmission efficiency. The adaptive beamforming algorithm is used to dynamically adjust the antenna array weight vector as follows:

[0113] Derivative the objective function of the adaptive algorithm:

[0114]

[0115] Iteratively update the weight vector of the antenna array:

[0116]

[0117] Where W (n+1) is the weight vector of the n+1th generation antenna array; W (n) is the weight vector of the n-th generation antenna array; μ is the learning rate.

[0118] The weight vector is normalized after each iterative update:

[0119]

[0120] When the objective function changes less than the preset threshold, the iteration stops and the optimal weight vector is output.

[0121] Example 2

[0122] Accordingly, this embodiment provides a signal enhancement system based on Beidou 5G fusion. The system is used to implement the signal enhancement method based on Beidou 5G fusion as described in Example 1 of the present invention, including a Beidou positioning module, a motion state analysis module, a weight vector derivation module, and a received signal strength optimization module.

[0124] The motion state analysis module is used to calculate the velocity vector of the vessel based on the acquired real-time latitude and longitude coordinate information to evaluate the motion state of the vessel including the swing amplitude and swing frequency.

[0125] The received signal strength optimization module is used for the weight vector derivation module, which is used to determine the beam pointing angle of the antenna array element of the ship's Beidou 5G integrated communication equipment according to the motion state of the ship, and derive the weight of the antenna array element through the beam pointing angle to obtain the weight vector of the antenna array.
