[0004] However, when existing 5G module communication devices are in use, high-frequency signals have problems such as phase noise sensitivity and limited coverage, while low-frequency signals face challenges such as complex channel interference and high synchronization accuracy requirements. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides a 5G module communication device based on a transparent antenna, which solves the problems of phase noise interfering with high-frequency signal communications and channel complexity interfering with low-frequency signals.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A 5G module communication device based on a transparent antenna, comprising:

[0007] The communication signal classification processing module is used to classify the communication signals transmitted by the communication signal acquisition module, match their corresponding frequencies with the frequency range division standard, generate high-frequency signals and low-frequency signals, and transmit the two separately;

[0008] The high-frequency signal analysis and processing module is used to analyze the acquired high-frequency signal, and to adjust the high-frequency signal with phase noise interference using a differential phase modulation method and generate differential phase adjustment information. For the high-frequency signal without noise interference, the module synchronizes the time of the transmitting end and the receiving end to generate time synchronization information, and transmits both to the communication signal processing output module;

[0009] The low-frequency signal analysis and processing module is used to analyze the acquired low-frequency signals, compare the signal interference strength with the interference preset value, generate a low-frequency processing signal, identify idle channels in the communication channel, classify them to generate channel classification information, and determine the stable period of non-overlapping channels;

[0010] The interference level value of the non-overlapping channel is calculated and the corresponding interference level is determined based on it. Frequency hopping processing is performed in combination with the stable period to generate low-frequency communication information and transmit it to the communication signal processing output module at the same time.

[0011] As a further solution of the present invention, it also includes a communication signal acquisition module and a communication signal processing and output module;

[0012] Communication signal acquisition module, used to collect 5G communication signals and corresponding basic information, and transmit them to the communication signal classification and processing module;

[0013] The communication signal processing output module is used to display the acquired differential phase adjustment information, time synchronization information and low-frequency communication information to the corresponding management personnel.

[0014] As a further solution of the present invention, the communication signal classification processing module generates high-frequency signals and low-frequency signals in the following specific manner:

[0015] Match the frequency of the 5G communication signal with the corresponding frequency range classification standard. If the frequency is between 30kHz and 300kHz, it is classified as a low-frequency signal. Conversely, if the frequency is greater than 300kHz, the corresponding 5G communication signal is classified as a high-frequency signal.

[0016] The high-frequency signals obtained by classification are transmitted to the high-frequency signal analysis and processing module, and the low-frequency signals obtained by classification are transmitted to the low-frequency signal analysis and processing module.

[0017] As a further solution of the present invention, the high-frequency signal analysis and processing module analyzes the high-frequency signal in the following specific manner:

[0018] According to the formula The phase noise of the high-frequency signal is calculated, where Pnoise(f) is the noise power within a 1 Hz bandwidth at a deviation from the carrier frequency f, and Pcarrice is the carrier power. It is compared with the preset noise value. If the phase noise is greater than the preset noise value, a noise interference processing signal is generated. Conversely, if the phase noise is less than the preset value, a time synchronization analysis signal is generated, and the two are analyzed separately.

[0019] As a further solution of the present invention, the specific manner in which the high-frequency signal analysis and processing module generates the differential phase adjustment information is as follows:

[0020] A narrow loop bandwidth is used to suppress the low-frequency noise of the VCO. At the same time, the loop response speed is improved by increasing the charge pump current, reducing high-frequency noise, and a differential phase modulation method is used for comprehensive regulation.

[0021] The original binary data is grouped and converted into relative phase difference through the differential encoder. Let the absolute phase of the previous symbol be , the absolute phase of the current symbol is = - ,in Determined by the input data, then based on Generate the corresponding carrier signal, s(t)=cos( + ),in is the carrier angular frequency;

[0022] Calculate the phase difference between adjacent symbols ,in is the phase difference between adjacent symbols, is the estimated phase of the nth symbol, The estimated phase of the n-1th symbol is then Mapped to the nearest phase difference set , restore the original data and generate the corresponding differential phase adjustment information.

[0023] As a further solution of the present invention, the specific manner in which the high-frequency signal analysis and processing module generates time synchronization information is as follows:

[0024] Set the high-frequency signal period to T, and when the counter counts to 0, it is marked as a zero-point signal, and when the counter counts to T / 2, it is marked as a midpoint signal;

[0025] The sending end performs synchronous processing, starts a high-frequency counter, and counts up at a fixed frequency. When the counter value is 0, the rising edge of the pulse sent through the I / O is used as the synchronization reference to trigger the zero point signal. When the counter value is T / 2, the falling edge of the pulse is sent to assist in phase calibration to trigger the midpoint signal.

[0026] The receiving end performs synchronous processing, detects the zero point signal and the midpoint signal, and records the timestamp t zero and t mind , start the local high-frequency counter, start the high-frequency counter, and when the zero-point signal is received, force the local counter to be reset to 0 to eliminate the phase difference. If the zero-point signal is not received in time, when the midpoint signal arrives, check whether the local counter value is close to T / 2, otherwise trigger resynchronization and generate time synchronization information.

[0027] As a further solution of the present invention, the specific manner in which the low-frequency signal analysis and processing module analyzes the acquired low-frequency signal is as follows:

[0028] Obtain the communication channel of the low-frequency signal, measure its interference intensity, and compare it with the preset interference value. If the interference intensity exceeds the preset value, generate a low-frequency processing signal;

[0029] Identify all idle channels and classify them into overlapping channels and non-overlapping channels based on whether the frequencies overlap. Non-overlapping channels are labeled i = 1, 2, ..., j, where j represents the number of non-overlapping channels. Monitor the signal strength with a period of T1.

[0030] The signal strength difference between adjacent time points is calculated, and the period when the difference is less than the threshold is determined to be a stable period. The stable period of all non-overlapping channels is recorded.

[0031] As a further solution of the present invention, the specific method in which the low-frequency signal analysis and processing module generates low-frequency communication information is:

[0032] Then calculate the interference level values ​​corresponding to all non-overlapping channels i, and the specific calculation formula is: , the received signal strength indicator is calculated according to the formula, where n represents all signal types corresponding to non-overlapping channel i, P n Represents the power of the nth signal, and then obtains the useful signal power P 有用 , and according to the formula P 干扰 = -P 有用 , calculate the interference level value P 干扰 , and according to the obtained interference level value P 干扰 Perform level classification to obtain the corresponding interference level;

[0033] Then, non-overlapping channels with interference levels less than the preset level are screened and recorded as pre-selected channels. The stable period information of the pre-selected channels is obtained, and they are sorted from front to back according to the stable period. Frequency hopping processing is performed in the sorting order to generate low-frequency communication information, which is then transmitted to the communication signal processing output module.

[0034] The present invention provides a 5G module communication device based on a transparent antenna. Compared with the existing technology, it has the following advantages:

[0035] The present invention optimizes the narrow loop bandwidth and charge pump current adjustment in combination with differential phase modulation, uses the phase difference of adjacent symbols to carry information, avoids dependence on the absolute phase of the carrier, reduces phase noise interference, and reduces demodulation complexity. It introduces a dual-reference synchronization mechanism of zero-point signal and midpoint signal, controls the synchronization error within the sub-cycle range through forced reset of the counter and judgment of the phase difference threshold, and reduces the synchronization failure rate.

[0036] The present invention combines interference level and stable period sorting, dynamically adjusts the frequency hopping order, reduces the number of communication interruptions of low-frequency signals in industrial Internet scenarios, reduces transmission delays, and realizes quantitative analysis of idle channel stability based on dual judgment of signal strength difference and stable period. Through the signal classification module, high-frequency and low-frequency signals are diverted to independent processing channels. The high-frequency channel focuses on phase noise suppression and synchronous calibration of high-speed data, and the low-frequency channel focuses on interference avoidance and channel optimization for wide-area coverage, thereby improving the overall system throughput. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Figure 1 This is a system block diagram of the present invention. DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making creative efforts are within the scope of protection of the present invention. Example 1

[0039] See also Figure 1 The present application provides a 5G module communication device based on a transparent antenna, including a communication signal acquisition module, a communication signal classification processing module, a high-frequency signal analysis and processing module, a low-frequency signal analysis and processing module, and a communication signal processing output module, and combined with Figure 1 It can be known that the functional modules are electrically connected in a unidirectional manner.

[0040] The communication signal acquisition module is used to obtain 5G communication signals and corresponding basic information, where the basic information is represented by the frequency of the 5G communication signal, and transmit it to the communication signal classification and processing module.

[0041] The communication signal classification processing module is used to classify the acquired 5G communication signals, obtain high-frequency signals and low-frequency signals, and generate signal classification information. The specific classification processing method is as follows:

[0042] Match the frequency of the 5G communication signal with the corresponding frequency range classification standard. If the frequency is between 30kHz and 300kHz, the corresponding 5G communication signal is classified as a low-frequency signal. Conversely, if the frequency is greater than 300kHz, the corresponding 5G communication signal is classified as a high-frequency signal.

[0043] The high-frequency signals obtained by classification are transmitted to the high-frequency signal analysis and processing module, and the low-frequency signals obtained by classification are transmitted to the low-frequency signal analysis and processing module.

[0044] Assume that in a certain 5G base station environment, the signal classification processing module collects the following three 5G communication signals in real time:

[0045] Signal A: The frequency is 200kHz. According to the classification standard, its frequency is in the range of 30kHz-300kHz. Therefore, Signal A is classified as a low-frequency signal and then transmitted to the low-frequency signal analysis and processing module.

[0046] Signal B: The frequency is 3.5 GHz, which belongs to the 5G Sub-6 GHz frequency band. It is also judged as a low-frequency signal and will be transmitted to the low-frequency signal analysis and processing module.

[0047] Signal C: The frequency is 28 GHz, which is greater than 6 GHz and meets the definition of a high-frequency signal. Signal C is transmitted to the high-frequency signal analysis and processing module.

[0048] High-frequency signal analysis and processing module, which is used to analyze the acquired high-frequency signal and obtain the phase noise corresponding to the high-frequency signal. The calculation method of the phase noise is as follows: Calculate, where Pnoise(f) is the noise power within a 1 Hz bandwidth at a deviation from the carrier frequency f, and Pcarrice is the carrier power. Compare it with a preset noise value, and the specific value of the preset noise value is set by the operator. If the phase noise is greater than the preset noise value, it indicates that the phase noise has an impact on high-frequency signal communication, and a noise interference processing signal is generated. Conversely, if the phase noise is less than the preset value, it indicates that the phase noise has no impact on high-frequency signal communication, and a time synchronization analysis signal is generated.

[0049] The generated noise interference processing signal is then analyzed. A narrow loop bandwidth (e.g., 100kHz) is used to suppress the VCO's low-frequency noise (<10kHz offset). The charge pump current (e.g., 10mA) is then increased to improve loop response speed and reduce high-frequency noise. For example, in a 28GHz PLL, setting the loop bandwidth to 50kHz reduces the phase noise at a 10kHz offset from -105dBc / Hz to -112dBc / Hz, but increases the lock time to 100μs. Differential phase modulation is then used for comprehensive adjustments, and the specific adjustment method is as follows:

[0050] The phase difference between adjacent symbols is used to carry information, avoiding direct reliance on the absolute phase of the carrier, thereby reducing sensitivity to phase noise. The original binary data is grouped (each 2 bits) and converted into relative phase difference through a differential encoder. Let the absolute phase of the previous symbol be , the absolute phase of the current symbol is = - ,in Determined by the input data, then based on Generate the corresponding carrier signal, s(t)=cos( + ),in The received signal is mixed with the local carrier (no need for precise phase synchronization) to obtain the baseband signal. After sampling, the phase estimate is obtained and the phase difference between adjacent symbols is calculated. ,in is the phase difference between adjacent symbols, is the estimated phase of the nth symbol, The estimated phase of the n-1th symbol is then Mapped to the nearest phase difference set , restore the original data, and generate the corresponding differential phase adjustment information, and transmit it to the communication signal processing output module at the same time. The corresponding 2-bit data mapping relationship is shown in the following table;

[0051]

[0052] Analyze the generated time synchronization analysis signal. Set the period of the high-frequency signal to T. The counter is triggered when the count value reaches 0, representing the phase starting point of the high-frequency signal and recorded as the zero-point signal. The counter is triggered when the count value reaches T / 2, representing the half-cycle position of the high-frequency signal and recorded as the midpoint signal. Then, perform synchronization analysis on the transmitter and receiver respectively.

[0053] Synchronize the transmitter, start the high-frequency counter, start counting from 0 at a fixed clock frequency, and count in the range of 0-T-1. Then synchronize based on the zero-point signal and the midpoint signal:

[0054] Zero point signal trigger: When the counter count value is 0, a zero point signal (such as a pulse rising edge) is sent through the I / O interface and marked as the synchronization reference.

[0055] Midpoint signal trigger: When the counter count value reaches \(T / 2\), a midpoint signal (such as a falling edge of a pulse) is sent to assist in phase calibration and generate time synchronization information;

[0056] The receiving end is synchronized and detects the input zero point signal and midpoint signal through hardware circuit (such as comparator) to extract its time stamp t zero and t mind , start the local high-frequency counter, set the initial count value to 0, and the clock frequency is consistent with the sending end (needs to be calibrated in advance through frequency synchronization technology, such as a phase-locked loop). When the zero-point signal is received, the local counter is immediately forced to reset to 0 to eliminate the accumulated phase difference. If the zero-point signal is not received in time (such as transmission delay), the midpoint signal is used to assist in judgment:

[0057] When the midpoint signal arrives, if the local counter value deviates from T / 2 by more than a threshold (e.g., \(\pm T / 4\)), the phase difference is determined to be too large, triggering resynchronization.

[0058] Time synchronization information is generated based on the synchronization processing of the sending end and the receiving end, and is transmitted to the communication signal processing output module.

[0059] The communication signal processing output module is used to display the acquired differential phase adjustment information and time synchronization information to the corresponding management personnel. Example 2

[0060] As the second embodiment of the present invention, it is implemented on the basis of the first embodiment and differs from the first embodiment in that the communication signal classification processing module transmits the generated low-frequency signal to the low-frequency signal analysis processing module and analyzes it.

[0061] A low-frequency signal analysis and processing module is used to analyze the acquired low-frequency signal, obtain the communication channel corresponding to the low-frequency signal, and obtain its signal interference strength, and compare it with the preset interference value. If the interference strength is greater than the preset interference value, it indicates that the low-frequency signal communication needs to be adjusted and processed, and a low-frequency processing signal is generated. Conversely, if the interference strength is less than the preset interference value, it indicates that the low-frequency signal communication does not need to be adjusted, and normal communication information is generated and transmitted to the communication signal processing output module.

[0062] Then, the generated low-frequency processed signal is analyzed to identify idle channels in all communication channels and classify them into overlapping channels and non-overlapping channels. The classification standard is based on the frequency between the communication channels. Overlapping channels refer to channels with partial or complete overlap in frequency ranges between channels. If used simultaneously, signal interference will occur. Non-overlapping channels refer to channels with independent frequency ranges and no overlap. When used simultaneously, no interference will occur. At the same time, all non-overlapping channels are obtained and labeled as i, and i=1, 2, ..., j, where j represents the number of non-overlapping channels. Then, with time T1 as a period, the signal strength corresponding to the non-overlapping channel i is analyzed, the difference in signal strength between adjacent unit times is calculated, and the stable period is determined based on the difference. Similarly, the stable period of all non-overlapping channels is obtained.

[0063] With T1 as a fixed period (T1 can be set according to the signal variation characteristics, such as 100ms), the signal strength of each non-overlapping channel i is monitored. Within each period, multiple unit times are further divided (for example, T1 is divided into 10 unit times, each unit time is 10ms), and the signal strength difference between adjacent unit times is calculated. , where S i (t) represents the signal strength of channel i at time t, S i (t-1) represents the signal strength of channel i at time t-1, and a stable threshold is set (e.g. 3dB), if within M consecutive unit times (M can be set as required, e.g. 5 unit times), the signal strength difference ΔSi between adjacent unit times is less than , then the period consisting of these M unit times is determined to be a stable period. By traversing the unit time in each cycle, all stable periods of non-overlapping channel i are obtained. Repeat the above operation for all non-overlapping channels to obtain the stable periods of all non-overlapping channels;

[0064] Assume that in a certain industrial Internet scenario, the low-frequency processing signal analysis module identifies six idle channels. After frequency range analysis, it is determined that channels 1, 3, and 5 are non-overlapping channels, and are labeled i=1, 2, and 3 respectively.

[0065] Signal strength monitoring is performed on these three non-overlapping channels with a period of T1 = 200ms, with each period divided into 20 time units (10ms each). For channel 1 (i = 1), for example, if the signal strength difference between the 3rd to 7th time units in the first period is less than the stability threshold ε = 3dB, then these five time units (i.e., 30-70ms) constitute a stable period for channel 1. Using the same method, the stable periods for channels 2 and 3 in this period and subsequent periods can be obtained, providing data support for selecting the optimal channel for low-frequency signal communication adjustments.

[0066] Then calculate the interference level values ​​corresponding to all non-overlapping channels i, and the specific calculation formula is: , the received signal strength indicator is calculated according to the formula, where n represents all signal types corresponding to non-overlapping channel i, P n Represents the power of the nth signal, and then obtains the useful signal power P 有用 , and according to the formula P 干扰 = -P 有用 , calculate the interference level value P 干扰 , and according to the obtained interference level value P 干扰 Perform level division to obtain the corresponding interference level, and the specific interference level division table is as follows:

[0067]

[0068] Then, non-overlapping channels with interference levels less than a preset level are selected as pre-selected channels, and frequency hopping communication processing is performed in combination with the stable period information corresponding to the pre-selected channels. The specific frequency hopping method is as follows:

[0069] The stable period information of the pre-selected channel is obtained, and the stable period information is sorted from front to back. Frequency hopping processing is performed in the sorted order to generate low-frequency communication information, which is then transmitted to the communication signal processing output module.

[0070] Communication signal processing output module, which is used to perform corresponding communication transmission according to the acquired low-frequency communication information. Example 3

[0071] As the third embodiment of the present invention, the focus is on combining the implementation processes of the first and second embodiments.

[0072] Some of the data in the above formulas are calculated based on their numerical values ​​and are not substituted into parameter units for calculation. At the same time, the contents not described in detail in this specification belong to the existing technology known to those skilled in the art.

[0073] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
