[0043] Figure 6 This is a schematic diagram of another wireless signal transceiver system in the embodiments of this disclosure. Detailed Implementation

[0044] To enable those skilled in the art to better understand the technical solutions of the embodiments of this disclosure, the following describes in further detail a wireless signal transceiver system and method, and a communication device provided by the embodiments of this disclosure, in conjunction with the accompanying drawings and specific implementation methods.

[0045] Embodiments of this disclosure will be described more fully below with reference to the accompanying drawings; however, the embodiments shown may be embodied in different forms and should not be construed as limited to the embodiments set forth in this disclosure. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will enable those skilled in the art to fully understand the scope of this disclosure.

[0046] This disclosure is not limited to the embodiments shown in the accompanying drawings, but includes modifications to the configuration based on the manufacturing process. Therefore, the areas illustrated in the drawings are schematic, and the shapes of the areas shown illustrate specific shapes of the areas, but are not intended to be limiting.

[0047] To improve the coverage of wireless communication in maritime areas, several solutions have been proposed, such as using high-power base stations, increasing the number of base stations, and using satellite communication. However, these solutions all have their limitations. High-power base stations and increasing the number of base stations are not only costly but also limited by the terrain and weather conditions of the sea area, making it difficult to achieve comprehensive coverage. Although satellite communication has a wide coverage area, it is greatly affected by weather and has high communication costs, hindering its widespread application. Therefore, how to design an economical and efficient maritime coverage system to solve the problems of poor communication quality and limited coverage in maritime areas has become an urgent technical problem to be solved in the field of wireless communication.

[0048] To address the aforementioned problems in the related technologies, in a first aspect, embodiments of this disclosure provide a wireless signal transceiver system, such as... Figure 1 and Figure 2 As shown, it includes: a first wireless signal transceiver module 1, configured to receive signals transmitted by a base station within a 360° range in the horizontal plane and transmit signals to the base station; the first wireless signal transceiver module 1 receives and transmits a first radio frequency (RF) signal; a first RF front-end 2, electrically connected to the first wireless signal transceiver module 1, configured to process the first RF signal for receiving and transmitting; a processing module 3, electrically connected to the first RF front-end 2, configured to perform mutual conversion between the first RF signal and a first digital signal; perform frequency offset calibration, transmission and reception synchronization, and filtering processing on the first digital signal; perform real-time monitoring of the signal strength of the first wireless signal transceiver module 1 within a 360° range in the horizontal plane; and perform forwarding and control of the first RF signal based on the signal strength of the first wireless signal transceiver module 1 within a 360° range in the horizontal plane.

[0049] The first RF front-end 2 is a multi-channel RF front-end, which can be used to amplify selected signals and improve signal strength. The first RF front-end 2 includes signal amplifiers (such as preamplifiers and power amplifiers), which can effectively amplify weak signals while maintaining signal linearity and stability; the first RF front-end 2 also includes filters to filter out unwanted frequency band signals. The processing module 3 is responsible for signal processing, control, and management. The processing module 3 includes a signal processor, a controller, and a memory, which can process and store signal data in real time and execute control commands.

[0050] The wireless signal transceiver system in this embodiment can be applied to wireless signal coverage in the sea area. By setting up a first wireless signal transceiver module 1, a first radio frequency front-end 2, and a processing module 3, the gain and stability of wireless signal coverage in the sea area can be significantly improved. At the same time, the anti-interference capability of the wireless signal transceiver system is also enhanced, realizing a wider coverage range and a more stable communication connection for wireless signal transmission and reception. This wireless signal transceiver system is not only suitable for scenarios such as maritime communication, maritime navigation, and maritime rescue, but can also provide stable and reliable communication guarantees for fields such as marine scientific research and marine resource development.

[0051] In some embodiments, such as Figure 3 As shown, the first wireless signal transceiver module 1 includes multiple sector antennas 10, which are arranged in a ring in the horizontal plane; any two adjacent sector antennas 10 are spaced apart from each other.

[0052] Each sector antenna 10 is responsible for receiving and transmitting base station signals in a specific direction. Multiple sector antennas 10 are installed in a ring layout, with each sector antenna 10 covering a certain angular range. The advantage of the ring layout is that it can provide omnidirectional signal coverage and reduce signal blind spots. By using multiple sector antennas 10 in a ring layout, the antenna gain can be increased, improving signal reception and transmission capabilities. Appropriate spacing should be maintained between adjacent sector antennas 10 to reduce mutual interference; the specific spacing can be optimized according to the type and operating frequency of the sector antenna 10. For example, for antennas operating in the microwave band, the spacing between adjacent sector antennas 10 can be set to approximately half a wavelength (i.e., 1 / 2 of its operating frequency wavelength).

[0053] In some embodiments, such as Figure 3 As shown, there are 8 sector antennas 10, and each sector antenna 10 receives and transmits the first radio frequency signal within a 45° angle range in the horizontal plane.

[0054] In some embodiments, the sector antenna 10 includes a directional antenna, which may include a planar antenna, a horn antenna, or a parabolic antenna.

[0055] The sector antenna 10 employs a high-gain directional antenna, which improves both the antenna's gain and directivity. The selection of a high-gain directional antenna requires consideration of factors such as antenna size, weight, cost, and performance.

[0056] In some embodiments, the wireless signal transceiver system further includes a second wireless signal transceiver module 4, configured to receive and transmit signals from a near-field terminal; the second wireless signal transceiver module 4 receives and transmits a second radio frequency (RF) signal; a second RF front-end 5, electrically connected to the second wireless signal transceiver module 4, is configured to receive and transmit the second RF signal; a processing module 3, also electrically connected to the second RF front-end 5, is further configured to perform mutual conversion between the second RF signal and a second digital signal; perform frequency offset calibration, transmission and reception synchronization, and filtering on the second digital signal; and forward the second RF signal based on the signal strength of the first wireless signal transceiver module 1 within a 360° range on the horizontal plane.

[0057] The second wireless signal transceiver module 4 employs a near-end coverage omnidirectional antenna, specifically an omnidirectional antenna for near-range coverage, responsible for receiving and transmitting signals from near-range terminals. The second radio frequency front-end 5 uses a multi-channel radio frequency front-end, which can amplify selected signals and improve signal strength. The second radio frequency front-end 5 includes signal amplifiers (such as preamplifiers and power amplifiers), which can effectively amplify weak signals while maintaining signal linearity and stability; the second radio frequency front-end 5 also includes a filter to filter out unwanted frequency band signals.

[0058] In some embodiments, such as Figure 2As shown, the processing module 3 includes: a signal conversion submodule 31, electrically connected to the first RF front-end 2 and the second RF front-end 5 respectively, configured to realize the mutual conversion between the first RF signal and the first digital signal, and the mutual conversion between the second RF signal and the second digital signal; a hardware processing physical layer protocol submodule 32, electrically connected to the signal conversion submodule 31, configured to perform modulation, demodulation, filtering, synchronization and timing, and error detection and correction processing on the first digital signal and the second digital signal; a digital signal processing submodule 33, electrically connected to the hardware processing physical layer protocol submodule 32, configured to perform frequency offset calibration, transmit / receive synchronization, and filtering processing on the first digital signal and the second digital signal; and a sector monitoring submodule 34, electrically connected to the digital signal processing submodule 33, configured to collect the signal strength data of each sector antenna in real time and perform quality control on the signal of each sector antenna. The quality index evaluation is performed by the sector selection submodule 35, which is electrically connected to the sector monitoring submodule 34. It is configured to use an adaptive algorithm to comprehensively evaluate the quality index evaluation results of the antenna signals in each sector and select the sector antenna with the best signal. The forwarding control submodule 36, which is electrically connected to the sector selection submodule 35, is configured to process and convert the second radio frequency signal collected by the second wireless signal transceiver module 4 through the digital signal processing submodule 33, the hardware processing physical layer protocol submodule 32, and the signal conversion submodule 31, and then forward it to the base station through the first radio frequency front-end 2 via the sector antenna with the best signal. It is also configured to process and convert the first radio frequency signal collected by the sector antenna with the best signal through the digital signal processing submodule 33, the hardware processing physical layer protocol submodule 32, and the signal conversion submodule 31, and then forward it to the terminal through the second radio frequency front-end 5 via the second wireless signal transceiver module 4.

[0059] In some embodiments, the hardware processing physical layer protocol submodule 32 includes a digital downconverter (DDC), a digital upconverter (DUC), a peak factor reduction (CFR, i.e., hard clipping and low-pass filtering of the input signal) and a digital predistortion (DPD, i.e., predistorting the input signal to achieve a linear output overall).

[0060] In some embodiments, the signal conversion submodule 31 includes an analog-to-digital converter (RFADC) and a digital-to-analog converter (RFDAC).

[0061] In some embodiments, the radio frequency signals received by the first wireless signal transceiver module 1 (i.e., each sector antenna) and the second wireless signal transceiver module 4 (i.e., near-end coverage omnidirectional antenna) are converted from radio frequency signals to digital signals by the signal conversion submodule 31 (i.e., RFADC) through the radio frequency front-end (i.e., the first radio frequency front-end 2 and the second radio frequency front-end 5). The digital signals are then processed by the hardware processing physical layer protocol submodule 32 (i.e., LOW PHY) and sent to the digital signal processing submodule 33 for frequency offset calibration, transmission and reception synchronization and filtering.

[0062] In some embodiments, the sector monitoring submodule 34 acquires signal strength data of each sector antenna in real time through the first radio frequency front-end 2 and the high-speed RFADC, and then converts the signal strength data of each sector antenna into digital signals for processing. The frequency of signal strength monitoring of each sector antenna can be adjusted according to actual needs, typically from hundreds to thousands of times per second (i.e., tens of Hz to thousands of Hz).

[0063] In some embodiments, the sector monitoring submodule 34 evaluates the signal quality indicators of each sector antenna. In addition to evaluating signal strength, the sector monitoring submodule 34 can also evaluate signal quality indicators such as signal-to-noise ratio and bit error rate to comprehensively judge the quality of the signal. The signal quality indicator evaluation can be implemented through digital signal processing algorithms, such as FFT (Fast Fourier Transform) and filters.

[0064] In some embodiments, the sector monitoring submodule 34 also has a fault detection function for each sector antenna. When a performance degradation or fault is detected in a certain sector antenna, it can automatically switch to other sector antennas for signal reception and transmission to ensure the normal operation of the system. Fault detection can be judged by indicators such as signal strength (e.g., a weak signal strength for a long time indicates an anomaly), signal-to-noise ratio (e.g., a low signal-to-noise ratio for a long time indicates an anomaly), and bit error rate (e.g., a high bit error rate for a long time indicates an anomaly). Once an anomaly is detected, the backup antenna is immediately activated or an alarm is issued.

[0065] In some embodiments, the sector selection submodule 35 employs an adaptive algorithm to dynamically select the optimal signal based on the signal strength data of each sector antenna monitored in real time by the sector monitoring submodule 34. For example, the sector selection submodule 35 can use algorithms such as weighted average method or maximum likelihood estimation method to select the optimal signal. The adaptive algorithm can comprehensively evaluate multiple dimensions of indicators such as signal strength, signal-to-noise ratio, and bit error rate of each sector antenna to select the sector antenna with the optimal signal.

[0066] In some embodiments, adaptive algorithms can achieve environmental perception; for example, adaptive algorithms use sensors and data acquisition modules to perceive changes in the surrounding environment in real time, such as wave height, wind speed, and temperature. Environmental perception can be achieved through various sensors, such as anemometers, temperature sensors, and humidity sensors. Adaptive algorithms can also achieve parameter adjustment; for example, based on environmental changes, adaptive algorithms dynamically adjust system parameters, such as antenna direction, signal amplification factor, and signal forwarding strategy, to adapt to different environmental conditions. Parameter adjustment can be achieved through preset rules or machine learning algorithms, optimizing based on historical and real-time data. Adaptive algorithms can also achieve performance optimization; for example, adaptive algorithms continuously learn and optimize to gradually improve system performance, ensuring optimal operation in various environments. Performance optimization can be achieved through a combination of online learning and offline training, continuously updating and improving the algorithm model.

[0067] In this embodiment, an adaptive algorithm enables the wireless signal transceiver system to maintain stable operation in different marine environments. The ring-shaped sector antenna layout and intelligent signal selection mechanism (the configuration of sector monitoring submodule 34 and sector selection submodule 35) significantly improve the quality and stability of the wireless signal transceiver system's communication signals.

[0068] In some embodiments, the digital signal processing submodule 33 includes a frequency offset calibration module, a transmit / receive synchronization module, and a digital signal processing module. The frequency offset calibration module performs frequency offset identification and calibration by recognizing the CP header of the communication frame structure. The transmit / receive synchronization module accurately locates the specific position (with an error at the sample point level) of the PSS signal (Primary Synchronization Signal, a signal used to help the receiving device synchronize with the wireless communication network) using a matched filtering algorithm, determines the starting point of the communication frame structure, and further determines the transmit / receive timing structure through the frame structure information configured by the system. The digital signal processing module performs filtering and other processing on the digital signal.

[0069] In some embodiments, the signal conversion submodule 31 uses an RF transceiver; the digital signal processing submodule 33 uses a programmable logic chip (FPGA); and the sector monitoring submodule 34, sector selection submodule 35, and forwarding control submodule 36 are integrated into an ARM chip or a DSP chip.

[0070] In some embodiments, such as Figure 2 and Figure 4As shown, the signal conversion submodule 31, the hardware processing physical layer protocol submodule 32, the digital signal processing submodule 33, the sector monitoring submodule 34, the sector selection submodule 35, and the forwarding control submodule 36 are integrated into a single chip. In this embodiment, the processing module 3 can use a Xilinx RFSOC chip, which contains abundant on-chip resources and can realize all functions of data processing and forwarding.

[0071] In some embodiments, such as Figure 5 As shown, the signal conversion submodule 31 can also be integrated into a single chip; the hardware processing physical layer protocol submodule 32 and the digital signal processing submodule 33 are integrated into a single chip; and the sector monitoring submodule 34, the sector selection submodule 35 and the forwarding control submodule 36 are integrated into a single chip.

[0072] In some embodiments, such as Figure 5 As shown, the chip containing the signal conversion submodule 31 communicates with the chips containing the hardware processing physical layer protocol submodule 32 and the digital signal processing submodule 33 via a JESD204 interface. The chips containing the hardware processing physical layer protocol submodule 32 and the digital signal processing submodule 33 communicate with the chips containing the sector monitoring submodule 34, the sector selection submodule 35, and the forwarding control submodule 36 via a high-speed port or bus.

[0073] In some embodiments, such as Figure 6 As shown, the wireless signal transceiver system also includes a first mixing module 6 and a second mixing module 7. The first mixing module 6 is electrically connected between the first radio frequency front-end 2 and the signal conversion submodule 31 and is configured to perform frequency conversion on the first radio frequency signal. The second mixing module 7 is electrically connected between the second radio frequency front-end 5 and the signal conversion submodule 31 and is configured to perform frequency conversion on the second radio frequency signal.

[0074] In some embodiments, both the first mixing module 6 and the second mixing module 7 employ mixers. The first radio frequency (RF) signal enters the analog-to-digital converter (RFADC) in the signal conversion submodule 31 from the first mixing module 6, where the frequency of the first RF signal is reduced. The first RF signal is then output from the digital-to-analog converter (RFDAC) in the signal conversion submodule 31 back to the first mixing module 6, where the frequency of the first RF signal is increased. The second mixing module 7 performs the same frequency transformation on the second RF signal as the first mixing module 6.

[0075] In this embodiment, the hardware integration of the wireless signal transceiver system involves integrating the first wireless signal transceiver module 1, the first radio frequency front-end 2, the processing module 3, the second radio frequency front-end 5, and the second wireless signal transceiver module 4 together to form a complete high-gain repeater system. Hardware integration needs to consider factors such as system size, weight, power consumption, and heat dissipation to ensure system reliability and durability. Software development of the wireless signal transceiver system requires the development of corresponding control software to implement functions such as signal processing, monitoring, and adaptive algorithms. Software development involves requirements analysis, design, coding, testing, and maintenance to ensure software stability and security. Testing of the wireless signal transceiver system requires system testing in laboratory and actual marine environments to verify system performance and reliability. Test content includes signal coverage, communication quality, anti-interference capability, and adaptive performance. System testing requires the development of detailed test plans and test cases, recording of test data and results, and data analysis and evaluation.

[0076] In some embodiments, a single high-gain directional antenna can be used instead of a multi-sector antenna. While a single high-gain directional antenna can reduce system complexity, it sacrifices some flexibility and coverage. It is suitable for communication needs in a specific direction. The advantages of directional antennas are high gain and strong directivity, but the disadvantages are limited coverage and difficulty in adapting to multi-directional signal requirements.

[0077] In some embodiments, a fixed gain setting can be used, that is, a fixed signal amplification factor is used instead of dynamically adjusting the signal amplification factor. Fixed gain simplifies system design, but may lead to poor performance in different environments, especially when signal strength varies significantly. The advantages of a fixed gain setting are system simplicity and low cost, but the disadvantages are poor adaptability and difficulty in coping with complex and changing environmental conditions.

[0078] In some embodiments, a single antenna can be used for signal reception and forwarding. Although the system structure is simple, its coverage and anti-interference capabilities are poor, making it unsuitable for communication needs in large sea areas. The advantages of a single-antenna system are its simple structure and low cost, but its disadvantages include limited coverage and poor anti-interference capabilities, making it difficult to meet the requirements of high-quality communication.

[0079] In some embodiments, the optimal signal can be selected for amplification and forwarding through manual intervention. While this can achieve high communication quality, it is complex to operate and unsuitable for applications requiring a high degree of automation. Manual switching offers the advantage of precise adjustment based on actual conditions, but its disadvantages include operational complexity, slow response time, and unsuitability for real-time communication needs.

[0080] In some embodiments, phased array antenna technology can be used to replace the ring-shaped multi-sector antenna array. Phased array antennas achieve precise beam control and optimization by adjusting the phase and amplitude of each antenna element. Introducing phased array antenna technology can further improve the gain and flexibility of the marine coverage system.
