Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wireless communication, and particularly relates to a digital communication device based on a 5G module. BACKGROUND

[0002] At present, with the rapid development of the fifth generation mobile communication (5G) technology, the digital communication device based on the 5G module has been widely applied in the fields of industrial control, remote medical treatment, intelligent transportation and emergency communication. The 5G communication system has the advantages of high bandwidth, low time delay and large connection density, however, it puts forward higher technical requirements for the communication device in the aspects of the radio frequency signal processing capability, the hardware electromagnetic compatibility and the power dynamic control. The traditional 5G communication device mainly consists of an antenna, a radio frequency front end, a power management, a baseband processing and a digital interface module. In the actual application, especially in the high frequency width (such as more than 100MHz) or the complex field intensity change environment, the existing technology still faces the following problems: the signal chain processing capability is insufficient: the radio frequency signal link usually includes multiple cascaded modules such as filtering, amplification, frequency conversion and analog-to-digital conversion. In the existing system, the modules lack collaborative optimization, which leads to the inflexible signal gain configuration, the insufficient out-of-band spurious suppression in the high frequency and high dynamic scene, and it is difficult to meet the real-time processing and signal fidelity requirements of the large bandwidth signal. The power control mechanism lags behind: the current device adopts the fixed power table or the simple lookup table logic for power configuration, and does not introduce the link state perception, gain calculation and dynamic feedback mechanism, which is difficult to cope with the link attenuation fluctuation, the field intensity mutation and other problems in the communication process, leading to the interference easily generated when the power is too large, and the insufficient signal-to-noise ratio when the power is too small. The electromagnetic interference (EMI) is significant: in the multi-module high-density integrated communication device, especially under the working condition of the 5G frequency band, the parasitic coupling and the radio frequency crosstalk are easily generated between different signal units. The existing shielding scheme mainly stays in the simple metal shell or the ground layer wiring, and does not form a structured and multi-level shielding system, so the anti-interference ability is insufficient. The system integration complexity is high: due to the high coupling degree, the non-uniform interface and the large module volume in the traditional communication system, the device has low overall integration and poor expandability.

[0003] In the Internet of Things terminal, the vehicle-mounted communication or the industrial embedded device, the existing solution is difficult to balance the dynamic trade-off among the volume, the power consumption and the performance, and to realize the high-fidelity processing of the signal, the accurate dynamic regulation of the power and the structural level suppression of the interference in the complex environment of high frequency width, multiple interferences and dynamic link changes.

[0004] Therefore, it is urgent to propose a new structure of the 5G communication device which can realize the modular integration, the high reliable transceiving and the high adaptability control on the basis of the dynamic adjustable output power, the enhanced signal processing precision and the reduced EMI interference ability, so as to improve the overall stability, the anti-interference performance and the engineering deployment adaptability of the system. Summary of the Invention

[0005] To address the aforementioned technical shortcomings, the present invention aims to propose a digital communication device based on a 5G module, which solves the technical problems of existing 5G communication modules having limited multi-band signal processing capabilities, inflexible output power configuration, and significant susceptibility to electromagnetic interference, especially in complex field strength environments or high-frequency interference environments, making it impossible to achieve stable signal transmission and precise power control.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a digital communication device based on a 5G module. The 5G-based digital communication device includes: The power supply unit is used to introduce external power, perform voltage regulation and level conversion operations in sequence, and supply power to the main control unit, 5G processing unit and digital transceiver unit respectively; the power supply unit uses a P-channel MOSFET to form a switch control structure to dynamically control the power supply status of the uplink and downlink signal paths of the 5G band in the 5G processing unit. The main control unit is used to centrally control the equipment through a software host computer and to perform dynamic adjustment operations on the equipment signal output; The 5G processing unit is used to perform modulation, demodulation, up-conversion, down-conversion and baseband protocol processing of 5G frequency band signals; The digital transceiver unit is used to realize bidirectional transmission and reception conversion between radio frequency signals and digital signals, and to interact with the 5G processing unit. The antenna transceiver unit includes an ANT segment and a BTS segment, wherein the ANT segment is used to receive external wireless signals and the BTS segment is used to transmit processed signals. The signal processing unit is used to perform channel equalization, filtering, amplitude and phase correction, and output power adjustment on 5G signals and digital signals under the control of the master control command.

[0007] Preferably, multiple units of the digital communication device are arranged in a hardware architecture with a multi-layer shielding structure, and the multi-layer shielding structure adopts a wiring layer design that introduces a grounding layer.

[0008] Preferably, the wiring layer design includes: shielding hole layer design, signal wiring layer design, and power wiring layer design.

[0009] Preferably, the top and bottom layers of the multi-layer shielding structure are provided with EMI physical shielding covers or metal shielding containers.

[0010] Preferably, the multi-layer shielding structure adopts a stripline topology to improve the ability to resist EMI interference.

[0011] Preferably, the digital transceiver unit is disposed on the top and bottom layers of the multi-layer shielded structure to reduce parasitic coupling.

[0012] Preferably, the process of centrally controlling the equipment through a software host computer and dynamically adjusting the equipment signal output specifically includes: The reference signal received power (RSRP) of the synchronization module in the device is obtained from the host computer. The value of RSRP ranges from -148 to 0 dBm and is used to characterize the field strength state of the current receiving channel. Based on the acquired reference signal received power RSRP, the link gain Gsyn between the antenna port and the synchronization module in the measurement device is measured, with a value ranging from -60 to +60 dB; and a power correction Δ is set to compensate for link non-ideals, with a value ranging from 0 to 50 dB. Based on the obtained reference signal received power RSRP and link gain Gsyn, the input channel power Pin is calculated using the following formula: ; Based on the calculated input channel power Pin, and according to the preset theoretical gain G of the entire device and the user-defined manual gain attenuation ATT, the current actual effective gain Gt is calculated. ; Applying the obtained current effective gain Gt to the input channel power Pin, according to the relationship... The output power Po is dynamically adjusted to meet the target transmit power range, and control commands are output to the digital transceiver unit and the 5G processing module to complete the power configuration.

[0013] Preferably, the signal processing unit, during signal processing, specifically includes: It receives radio frequency signals from the antenna transceiver unit. The radio frequency signals are frequency isolated by a duplexer, so that the uplink transmit signal and the downlink receive signal do not interfere with each other on the physical path, thus realizing the parallel transmission of transmit and receive signals. By using a power divider and coupler installed at the front end of the RF link, the transmit power of the RF signal is path-averaged and the direction is controlled to output an optimized RF signal. The optimized radio frequency signal is input to a bandpass filter, which performs a preset filtering operation on the radio frequency signal in a specific frequency band to suppress out-of-band interference frequencies and output an effective signal within the target frequency band. The effective signal within the standard frequency band is passed sequentially through a low-noise amplifier, a multi-stage gain amplifier, and a signal filter. While maintaining the improvement of the signal-to-noise ratio, signal gain amplification and frequency spurious suppression are performed to output the intermediate frequency signal with the target power requirement. The intermediate frequency signal with the target power requirement is input to the power amplifier for further amplification to compensate for path loss during subsequent transmission. The signal after further power amplification is then converted into a digital signal by an analog-to-digital converter. The digital transceiver unit performs demodulation, decoding, and data restoration operations on the digital signal, and finally outputs the original information data stream.

[0014] The beneficial effects of this invention are as follows: By constructing a multi-stage signal processing link consisting of a duplexer, power divider, filter, LNA, PA, and ADC, and in conjunction with a configurable output power control algorithm of the main control unit, this invention achieves precise adjustment and gain control of high-bandwidth 5G radio frequency signals, effectively improving the signal transmission quality and dynamic response capability of the device in complex environments.

[0015] This invention employs a multi-layer shielding structure, including a grounding layer, a signal wiring layer, a power wiring layer, and an EMI physical shield, and introduces a stripline topology design to suppress parasitic coupling and external electromagnetic interference at the hardware level. At the same time, by integrating power supply, control, and transceiver functions through a modular architecture, the system integration process is simplified, and the reliability and scalability of the equipment are improved. Attached Figure Description

[0016] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0017] Figure 1 This is a schematic diagram of a digital communication device based on a 5G module according to the present invention. Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: As Figure 1 The diagram shown is a flowchart of the first embodiment of the digital communication device based on the 5G module of the present invention, which presents the first embodiment of the digital communication device based on the 5G module of the present invention.

[0020] In the first embodiment, the digital communication device based on the 5G module includes: The power supply unit, after receiving external power, sequentially performs voltage regulation and level conversion operations, supplying power to the main control unit, 5G processing unit, and digital transceiver unit. The power supply unit utilizes a P-channel MOSFET to form a switching control structure, dynamically controlling the power supply status of the uplink and downlink signal paths in the 5G band of the 5G processing unit. Multiple units of the device are housed within a multi-layered shielded hardware architecture. This multi-layered shielding structure employs a layered wiring design with a grounding layer, including shielding via layers, signal wiring layers, and power wiring layers. The top and bottom layers of the multi-layered shielding structure are equipped with EMI physical shielding covers or metal shielding containers. The multi-layered shielding structure uses a stripline topology to improve EMI immunity. The digital transceiver unit is located on the top and bottom layers of the multi-layered shielding structure to reduce parasitic coupling.

[0021] It should be noted that the P-channel MOSFET in the power supply unit constitutes a high-side switching structure. By software-controllably pulling its gate voltage low, independent on / off control of the power required for uplink and downlink in the 5G processing unit can be achieved. This structure not only has the advantages of fast response speed and low control power consumption, but also enables time-sharing power supply scheduling management for high-power modules such as power amplifiers, thereby improving overall power efficiency and extending equipment life. The layered wiring design introduces a ground plane to physically isolate the signal wiring layer, power wiring layer, and shielding via layer, effectively reducing the risk of crosstalk of high-frequency signals on the PCB.

[0022] It is understood that the multi-layer shielding structure in this embodiment is not limited to physical shielding, but rather combines with stripline topology design through layer-to-layer integration to form an EMI suppression network with good electrical continuity and controllable reflection paths. This network can form an envelope-like closed loop in the high-frequency transmission path, thereby suppressing the dual effects of radiated and induced interference. This structure is particularly suitable for 5G Sub-6GHz and millimeter-wave band communication module packaging, which is beneficial for improving the stability and RF consistency of communication links.

[0023] It should be understood that, compared with traditional 5G equipment solutions that use single-layer metal shielding or simple grounding grid structures, the shielding solution of "multi-layer structure + stripline + metal can seal" adopted in this invention has higher electromagnetic compatibility and lower risk of wiring interference coupling. Especially in complex scenarios such as high-density module deployment, space-constrained or multi-link collaborative communication, this structure significantly reduces parasitic capacitance, signal reflection and cross-modulation phenomena, and improves the EMC performance and upper limit of the operating frequency of the system.

[0024] The main control unit is used to centrally control the equipment via a host computer software and to perform dynamic adjustment operations on the equipment signal output. Specifically, the process of centrally controlling the equipment via a host computer software and performing dynamic adjustment operations on the equipment signal output includes: obtaining the reference signal received power RSRP of the synchronization module in the equipment from the host computer. The RSRP value ranges from -148 to 0 dBm and is used to characterize the current field strength state of the receiving channel; based on the obtained reference signal received power RSRP, measuring the link gain Gsyn between the antenna port and the synchronization module in the equipment, with a value range of -60 to +60 dB; and setting a power correction amount Δ to compensate for link non-ideals, with a value range of 0 to 50 dB; and calculating the input channel power Pin based on the obtained reference signal received power RSRP and link gain Gsyn, using the following formula: Based on the calculated input channel power Pin, and according to the preset theoretical gain G of the entire device and the user-defined manual gain attenuation ATT, the current actual effective gain Gt is calculated. Apply the obtained current effective gain Gt to the input channel power Pin, according to the relationship... The output power Po is dynamically adjusted to meet the target transmit power range, and control commands are output to the digital transceiver unit and the 5G processing module to complete the power configuration.

[0025] It should be understood that, compared to traditional control schemes that rely on fixed power meter readings, the dynamic calculation-based control mechanism proposed in this invention offers greater flexibility and accuracy, making it particularly suitable for industrial or outdoor mobile communication scenarios with dynamic field strength variations, environmental interference, or drastic fluctuations in link quality. This mechanism also supports extension to closed-loop adaptive optimization systems, and in the future, it can be combined with a feedback power detection module and machine learning algorithms to achieve adaptive Po optimization control.

[0026] The 5G processing unit is used to perform modulation, demodulation, up-conversion, down-conversion and baseband protocol processing of 5G frequency band signals; It should be noted that the 5G processing unit refers to the core RF baseband processing module integrated into this device for the 5G NR protocol stack. Internally, it includes a physical layer (PHY), a media access control layer (MAC), and some protocol adaptation logic, and is equipped with a modulation / demodulation submodule, up-conversion and down-conversion submodules, clock synchronization circuitry, and channel estimation and equalization logic. The 5G processing unit modulates the input baseband signal (e.g., QPSK, 16QAM, 64QAM) and up-converts it into an RF signal operating in the 5G frequency band, while simultaneously performing demodulation and restoration operations on the received down-converted signal.

[0027] It is understandable that the 5G processing unit not only performs traditional data modulation and radio frequency conversion, but more importantly, it supports the physical layer enhancements in the 5G protocol, such as carrier aggregation (CA), multiple-input multiple-output (MIMO), beamforming, and dynamic spectrum scheduling. The 5G processing unit in this invention also supports flexibly configurable modulation and coding schemes (MCS), HARQ buffering mechanisms, and dynamic power parameter synchronization with the main control unit, thereby ensuring end-to-end data link quality.

[0028] It should be understood that, compared to traditional communication systems that only have fixed-format processing capabilities, the 5G processing unit in this invention adopts a reconfigurable hardware architecture or SoC integration mode, which makes it highly scalable and protocol compatible, applicable to mainstream Sub-6GHz frequency bands such as n41 and n78, and supports parallel processing of multiple antenna paths and channel state feedback function, significantly improving the device's adaptability to complex wireless environments and the robustness of communication links.

[0029] The digital transceiver unit is used to realize bidirectional transmission and reception conversion between radio frequency signals and digital signals, and to interact with the 5G processing unit. It should be noted that the digital transceiver unit typically includes an analog-to-digital converter (ADC), a digital-to-analog converter (DAC), a clock synchronization module, a channel equalization circuit, and an I / Q demapping module. It is used to convert the digital baseband signal from the 5G processing unit into an analog signal on the transmit path and pass it to the RF link for transmission. On the receive path, it converts the down-converted analog signal from the RF front end into a digital signal and restores its baseband information for further demodulation by the 5G processing unit, serving as a bridge between the analog and digital domains.

[0030] Understandably, the ADC and DAC in the digital transceiver unit can adopt a multi-channel parallel architecture and support high sampling rates (e.g., above 200 MSps) and high resolutions (e.g., 12-14 bits) to meet the high linearity and low distortion requirements of 5G systems for broadband signal processing. Internally, it employs I / Q decoupling and complex vector processing mechanisms to accurately recover the amplitude and phase information of the received signal. Simultaneously, it supports real-time exchange of control parameters and bit error rate information with the main control unit, enabling parameter-coordinated scheduling under link-state awareness.

[0031] It should be understood that, compared to traditional communication modules that use independent ADC / DAC components and do not form a closed-loop control, the digital transceiver unit in this invention has a higher degree of integration and has multi-protocol compatibility with the 5G processing unit interface (such as LVDS, JESD204B, MIPI interface, etc.), which can form a high-speed, low-latency interconnect at the chip level. At the same time, the power consumption control logic of the unit supports dynamic switching of working state, effectively reducing energy consumption in the silent state and improving the overall battery life and heat dissipation efficiency in edge application scenarios.

[0032] The antenna transceiver unit includes an ANT segment and a BTS segment, wherein the ANT segment is used to receive external wireless signals and the BTS segment is used to transmit processed signals. It should be noted that the ANT (Antenna Receive) and BTS (Base Transmit) segments in the antenna transceiver unit are connected to the signal processing link through key components such as duplexers, isolators, matching circuits, and RF switches, achieving physical layer isolation of the signal transmission and reception paths. The ANT segment is primarily responsible for receiving 5G wireless signals, down-converting them, and then transmitting them to the 5G processing unit. The BTS segment up-converts and amplifies the modulated signal output from the 5G processing unit before transmitting it. The two segments optimize coupling interference through differential cabling, bandpass matching, and electrical decoupling, effectively ensuring the quality of the transmitted and received signals at the antenna port.

[0033] It is understandable that the antenna transceiver unit is the radio frequency interface through which the 5G communication system of this invention interacts with the external environment, and its performance directly affects the system's link quality and data throughput. By setting independent impedance matching networks and beam control units in the ANT and BTS segments, stable signal reception and transmission capabilities can be achieved in multi-band environments. Simultaneously, the ANT and BTS segments can adopt time-division multiplexing, frequency domain isolation, or MIMO parallel structures to adapt to the physical layer modulation requirements under different communication standards.

[0034] It should be understood that, compared to traditional shared single-antenna designs or fixed directional antenna configurations, the ANT and BTS segment structures of this invention support flexible radio frequency path control and can work in conjunction with dynamic beamforming algorithms to improve channel capacity and directional gain while maintaining transmit-receive separation. This makes it particularly suitable for complex wireless environments with multipath propagation, obstacle obstruction, or high terminal mobility.

[0035] The signal processing unit is used to perform channel equalization, filtering, amplitude and phase correction, and output power adjustment on 5G signals and digital signals under the control of the master control command.

[0036] The signal processing unit, in its signal processing process, specifically includes: receiving radio frequency (RF) signals from the antenna transceiver unit; the RF signals are frequency-domain isolated via a duplexer to ensure that the uplink transmit signal and downlink receive signal do not interfere with each other on the physical path, thus achieving parallel transmission of the transmit and receive signals; using a power divider and coupler located at the front end of the RF link to perform path averaging and direction control on the transmit power of the RF signal, outputting an optimized RF signal; inputting the optimized RF signal to a bandpass filter to perform preset filtering operations on the RF signal in a specific frequency band, suppressing out-of-band interference frequencies, and outputting an effective signal within the target frequency band; passing the effective signal within the target frequency band sequentially through a low-noise amplifier, a multi-stage gain amplifier, and a signal filter to perform signal gain amplification and frequency spurious suppression while maintaining a higher signal-to-noise ratio, outputting an intermediate frequency (IF) signal with the target power requirement; inputting the IF signal with the target power requirement to a power amplifier for further amplification to compensate for path loss during subsequent transmission; converting the further amplified signal into a digital signal sequentially via an analog-to-digital converter, and having the digital transceiver unit perform demodulation, decoding, and data restoration operations on the digital signal, finally outputting the original information data stream.

[0037] It should be noted that the signal processing unit constructs a closed-loop optimized RF signal processing path. Starting from antenna reception, it performs duplexing, power splitting and coupling, filtering and amplification, and finally analog-to-digital conversion, realizing multi-stage signal enhancement and spurious suppression from the analog domain to the digital domain. Specifically, the duplexer physically isolates the transmit and receive paths, ensuring that uplink and downlink signals do not interfere with each other; the power splitter and coupler rationally distribute RF power between the main signal path and the test / monitoring path, and optimize the transmit direction characteristics; the bandpass filter selects signals in specific frequency bands, suppressing out-of-band harmonics and environmental interference.

[0038] Understandably, the functional modules in this signal processing link are cascaded sequentially, ensuring signal quality control at each stage while avoiding issues such as inter-stage reflections and phase mismatches. For example, the low-noise amplifier (LNA) is located at the front end of the receiving link, prioritizing the enhancement of weak RF signals without introducing excessive noise; the multi-stage gain amplifier achieves linear gain enhancement through progressively adjustable steps; and the power amplifier (PA) is located at the end of the transmitting link, used to boost the signal to the power level required for antenna transmission. All modules are configured with parameters and switch operating states under the command of the main control unit.

[0039] It should be understood that, compared to traditional RF processing solutions composed of disparate modules, this invention integrates power control, signal enhancement, and filtering suppression into a unified processing path, and adopts a collaborative processing mechanism of configurable gain control + power closed-loop adjustment + dynamic filter parameter matching, making the gain response curve of the whole device to the input signal smoother and the quality control of the output signal more stable. It is particularly suitable for communication scenarios in 5G high-frequency bands, high bandwidth, and complex environments.
