Description
Technical Field
[0001] The present application relates to the field of wireless transmission technology, and in particular to a multimodal wireless signal fusion method, product, device and medium. Background Art
[0002] Signal transmission and reception are fundamental components of wireless communication systems. Technologies typically receive wireless signals through hardware devices like antennas and analyze and process them using signal processing algorithms. Spectrum resources are valuable in wireless communications, and related technologies employ static or dynamic spectrum allocation strategies to manage these resources. Static allocation strategies allocate fixed spectrum segments to different communication services based on pre-set rules or protocols, while dynamic allocation strategies dynamically adjust spectrum resource allocation based on real-time communication needs and spectrum usage.
[0003] However, in some wireless communication scenarios, it is necessary to process multiple types of data (i.e., multimodal data) from different sensors or devices. The relevant technologies lack flexible management of multimodal data, resulting in insufficient utilization of spectrum resources. Summary of the Invention
[0004] In order to improve spectrum resource utilization, the present application provides a multimodal wireless signal fusion method, product, device and medium.
[0005] In a first aspect, the present application provides a multimodal wireless signal fusion method, which adopts the following technical solutions:
[0006] A multimodal wireless signal fusion method, comprising:
[0007] Acquire a wireless signal to be transmitted, and if there are multiple wireless signals to be transmitted, analyze the signal mode and signal type of each wireless signal;
[0008] Determining a priority based on the signal type of each wireless signal;
[0009] Obtaining an available frequency band, dividing a plurality of wireless signals into signal groups according to signal patterns, and allocating a subchannel for each signal group from the available frequency band;
[0010] Based on the priority and receiving time of each wireless signal in the signal group corresponding to the target subchannel, spectrum resources are allocated to each wireless signal in the target subchannel, and the target subchannel is any subchannel divided from the available frequency band.
[0011] By adopting the above technical solution, the wireless signal to be transmitted is obtained, ensuring that all wireless signals that need to be transmitted are collected. Analyzing the signal mode and signal type helps to understand the basic characteristics of each wireless signal. By identifying the signal type, different processing priorities and resource allocation strategies can be provided for different types of signals. Determining the priority can ensure that important or urgent wireless signals can be transmitted first. Obtaining the available frequency band ensures that the wireless signal has available spectrum resources for transmission. The wireless signal is divided into signal groups according to the signal mode, and a sub-channel is allocated for each signal group. This can ensure that wireless signals with similar characteristics are transmitted within the same spectrum range, reducing interference between signals. Within the same sub-channel, spectrum resources are allocated according to the priority and reception time of the wireless signal, ensuring that important or urgent signals are transmitted first, while reducing conflicts and waiting time between signals. This application improves the utilization rate of spectrum resources and ensures the stability and reliability of the system.
[0012] In a preferred example, the present application may be further configured as follows: allocating spectrum resources to each wireless signal in the target sub-channel based on the priority and reception time of each wireless signal in the signal group corresponding to the target sub-channel includes:
[0013] Arrange each wireless signal in the signal group corresponding to the target subchannel from high to low priority to obtain a priority list, and determine a first position of the target wireless signal in the priority list, where the target wireless signal is any one of the multiple wireless signals;
[0014] Arrange the wireless signals in the signal group corresponding to the target subchannel from earliest to latest according to the reception time to obtain a reception time list, and determine the second position of the target wireless signal in the reception time list;
[0015] Determining a position of the target wireless signal in a target queue based on the first position and the second position, the target queue including an ordering of the wireless signals in the signal group corresponding to the target subchannel;
[0016] Spectrum resources are allocated to each wireless signal in the target sub-channel based on the target queue.
[0017] By adopting the above technical solution, a more reasonable position can be determined for the target wireless signal in the target queue based on a comprehensive sorting of priority and reception time. This position takes into account both the urgency of the signal and the arrival time of the signal. By allocating spectrum resources to each wireless signal based on the target queue, dynamic resource allocation can be achieved, ensuring that each wireless signal can obtain sufficient spectrum resources for transmission, thereby reducing the possibility of signal loss or transmission errors.
[0018] In a preferred example, the present application may be further configured as follows: allocating spectrum resources to each wireless signal in the target sub-channel based on the target queue includes:
[0019] Starting from the first wireless signal in the target queue, transmitting wireless signals in sequence;
[0020] Treat any wireless signal in the target queue that has not started transmission as an untransmitted signal, calculate the time difference between the reception time of the untransmitted signal and the current time, and compare the time difference with a preset delay time;
[0021] If the time difference reaches the preset delay time, the untransmitted signal and the wireless signal being transmitted at the current moment are transmitted in parallel.
[0022] By adopting the above technical solution, transmission starts from the first wireless signal in the target queue, ensuring that the transmission order of the signals is consistent with their order in the queue, avoiding the problem of signal loss or disorder, and calculating the time difference between the reception time of the untransmitted signal and the current time, the waiting time of the signal can be understood in real time. When the waiting time of the untransmitted signal reaches the preset delay time, it is transmitted in parallel with the currently transmitted signal, which can make full use of the parallel processing capabilities of the system. Parallel transmission helps to reduce the waiting time of the signal and improve the throughput and response speed of the system.
[0023] In a preferred example, the present application may be further configured as follows: analyzing the signal mode and signal type of each wireless signal includes:
[0024] Sampling and quantizing the received target wireless signal to obtain the target wireless signal in the form of a digital signal;
[0025] Extracting features of the target wireless signal to obtain at least one of a time domain feature, a frequency domain feature, and a modulation feature;
[0026] The at least one feature is input into a preset recognition model, and the preset recognition model parses to obtain a signal mode and a signal type of the target wireless signal.
[0027] By adopting the above technical solution, the received target wireless signal is sampled and quantized and converted into a digital signal form, which helps to reduce signal distortion and noise interference during transmission and storage, improve signal quality, and extract features of the target wireless signal. The features can reflect the basic properties and transmission characteristics of the signal, providing powerful input information for the subsequent recognition model. The extracted features are analyzed using the preset recognition model, which can quickly and accurately identify the signal pattern and signal type of the wireless signal.
[0028] In a preferred example, the present application may be further configured as follows: dividing a sub-channel for each signal group from the available frequency band includes:
[0029] allocating initial subchannels for each signal group from the available frequency band based on a signal pattern of each signal group;
[0030] Check whether there is a frequency band intersection between every two initial sub-channels;
[0031] If so, determine the number of wireless signals corresponding to each of the two initial sub-channels with the frequency band intersection, and adjust the two initial sub-channels with the frequency band intersection based on the number of wireless signals to obtain adjusted sub-channels of each signal group.
[0032] By adopting the above technical solution, the initial sub-channels are divided from the available frequency band according to the signal mode of each signal group, which can ensure that each signal group obtains spectrum resources that match its characteristics. By finding the intersection of frequency bands, potential spectrum conflicts can be discovered and resolved in a timely manner, mutual interference between signals can be avoided, and the quality of signal transmission can be guaranteed. When a frequency band intersection is found, the two initial sub-channels with the intersection are adjusted according to the number of wireless signals corresponding to each, which can ensure that each signal group can obtain sufficient spectrum resources for transmission.
[0033] In a preferred example, the present application may be further configured as follows: the method further includes:
[0034] If the number of the wireless signal to be transmitted is one, obtaining an available frequency band and a signal mode of the wireless signal;
[0035] Selecting an applicable frequency band for the wireless signal from the available frequency bands based on the signal pattern;
[0036] Determine whether there is a signal being transmitted in the applicable frequency band, and if so, obtain the frequency of the wireless signal, and determine the superposition method based on the frequency;
[0037] The wireless signal is superimposed on the signal being transmitted in the applicable frequency band by using the superposition method.
[0038] By adopting the above technical solution, when there is only one wireless signal to be transmitted, the most suitable applicable frequency band can be accurately selected from the available frequency bands based on the signal pattern of the signal. If the applicable frequency band is occupied, the superposition method is determined based on the frequency of the wireless signal, and an attempt is made to superimpose the new signal on the signal being transmitted. By simultaneously transmitting multiple signals on the same frequency band, the system's transmission capacity and spectrum efficiency are improved.
[0039] In a preferred example, the present application may be further configured as follows: determining the superposition mode based on the frequency includes:
[0040] comparing the frequency with a preset frequency threshold;
[0041] If the frequency exceeds the preset frequency threshold, determining the frequency division multiplexing mode to be the superposition mode;
[0042] If the frequency does not exceed the preset frequency threshold, the time division multiplexing mode is determined to be the superposition mode.
[0043] By adopting the above technical solution, the frequency of the wireless signal is compared with the preset frequency threshold, and frequency division multiplexing or time division multiplexing is intelligently selected as the superposition method. This can ensure that the most appropriate multiplexing method is selected according to the frequency characteristics of the signal, thereby improving the utilization efficiency of spectrum resources and the quality of signal transmission.

[0056] The following is combined with Figure 1 -Attached Figure 2 This application is described in further detail.

If sensitive information is involved, the separate consent of the information subject needs to be obtained. The embodiments also need to be implemented with the authorization and consent of the object.
[0061] The present application embodiment provides a multi-modal wireless signal fusion method, such as Figure 1 As shown, the method provided in the embodiment of the present application is performed by an electronic device, which can be a server or a terminal device, wherein the server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smartphone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, which is not limited in the embodiment of the present application. The method includes steps S101 to S104, wherein:
[0062] S101: Acquire a wireless signal to be transmitted. If there are multiple wireless signals to be transmitted, analyze the signal mode and signal type of each wireless signal.
[0063] Specifically, ensure that signal receiving devices such as antennas and receivers are correctly connected and in working condition. Due to network conditions, wireless signals may be received but not transmitted immediately. The wireless signals to be transmitted are wireless signals obtained before the current moment but not transmitted. The electronic device is connected to the signal receiving device to check the number of received wireless signals to be transmitted.
[0064] In a possible scenario, the number of wireless signals to be transmitted is one, available frequency bands at the current moment are obtained, and an applicable frequency band suitable for transmission of the wireless signal is determined from the available frequency bands, and the wireless signal is transmitted on the applicable frequency band.
[0065] In another possible scenario, there are multiple wireless signals to be transmitted, and the signal mode and signal type of each wireless signal are analyzed. The signal modes include: Bluetooth signals, 4G signals, 5G signals, broadcast signals, etc. The signal type is used to characterize the service type, such as video calls, email transmission, emergency communications (such as 119), etc.
[0066] S102: Determine a priority based on the signal type of each wireless signal.
[0067] Specifically, a correspondence between signal types and priority values can be pre-set based on practical experience. For example, emergency communications have the highest priority, followed by video calls, and then email transmissions. Signal types with higher priority are assigned higher priority values and stored in the electronic device. Based on the pre-set correspondence, a priority value is assigned to each acquired wireless signal.
[0068] S103: Obtain an available frequency band, divide multiple wireless signals into signal groups according to signal modes, and allocate a sub-channel for each signal group from the available frequency band to ensure that the sub-channels do not interfere with each other.
[0069] Specifically, currently available spectrum resources are scanned to determine the available frequency band range.
[0070] S104 . Allocate spectrum resources to each wireless signal in a target subchannel based on the priority and reception time of each wireless signal in the signal group corresponding to the target subchannel. The target subchannel is any subchannel divided from an available frequency band.
[0071] Specifically, the wireless signals in the target subchannel are sorted according to their priority and reception time to obtain a target queue, and spectrum resources are allocated to each wireless signal in the target subchannel based on the target queue.
[0072] This embodiment ensures that all wireless signals that need to be transmitted are collected by acquiring wireless signals to be transmitted. Analyzing signal patterns and signal types helps to understand the basic characteristics of each wireless signal. By identifying signal types, different processing priorities and resource allocation strategies can be provided for different types of signals. Determining priorities can ensure that important or urgent wireless signals can be transmitted first. Acquiring available frequency bands ensures that wireless signals have available spectrum resources for transmission. Dividing wireless signals into signal groups according to signal patterns and allocating a sub-channel for each signal group can ensure that wireless signals with similar characteristics are transmitted within the same spectrum range, reducing interference between signals. Within the same sub-channel, spectrum resources are allocated according to the priority and reception time of the wireless signal, ensuring that important or urgent signals are transmitted first, while reducing conflicts and waiting time between signals. This application improves the utilization rate of spectrum resources and ensures the stability and reliability of the system.
[0073] A possible implementation of the embodiment of the present application allocates spectrum resources to each wireless signal in a target subchannel based on the priority and reception time of each wireless signal in the signal group corresponding to the target subchannel, including:
[0074] Arrange each wireless signal in the signal group corresponding to the target subchannel from high to low priority to obtain a priority list, and determine the first position of the target wireless signal in the priority list, where the target wireless signal is any one of the multiple wireless signals;
[0075] Arrange the wireless signals in the signal group corresponding to the target subchannel from earliest to latest according to the reception time to obtain a reception time list, and determine the second position of the target wireless signal in the reception time list;
[0076] Determining a position of the target wireless signal in a target queue based on the first position and the second position, where the target queue includes an ordering of the wireless signals in the signal group corresponding to the target subchannel;
[0077] Spectrum resources are allocated to each wireless signal in the target sub-channel based on the target queue.
[0078] In this embodiment, each signal type is assigned a priority value, with higher priority values indicating higher priority. Wireless signals are sorted from highest to lowest priority to create a priority list. Wireless signals of the same signal type are sorted from earliest to latest reception time. Furthermore, wireless signals in the signal group corresponding to the target subchannel are sorted from earliest to latest reception time to create a reception time list.
[0079] The first position represents the target wireless signal's position in the priority list, and the second position represents the target wireless signal's position in the reception time list. If the target wireless signal is ranked fifth in the priority list, the first position is 5. Furthermore, a weighted sum of the first and second positions is performed to determine the target wireless signal's position in the target queue. The weights corresponding to the first and second positions can be set based on actual needs and are not specifically limited in this embodiment. After determining the positions of the wireless signals corresponding to the target subchannel, the wireless signals are sorted from smallest to largest according to their position values. The result of this sorting is the target queue.
[0080] This embodiment uses a comprehensive ranking based on priority and reception time to determine a more reasonable position for the target wireless signal in the target queue. This position takes into account both the urgency of the signal and the arrival time of the signal. By allocating spectrum resources to each wireless signal based on the target queue, dynamic resource allocation can be achieved, ensuring that each wireless signal can obtain sufficient spectrum resources for transmission, thereby reducing the possibility of signal loss or transmission errors.
[0081] A possible implementation of the embodiment of the present application allocates spectrum resources to each wireless signal in a target subchannel based on a target queue, including:
[0082] Starting from the first wireless signal in the target queue, wireless signals are transmitted in sequence;
[0083] Any wireless signal in the target queue that has not started transmission is regarded as an untransmitted signal, the time difference between the reception time of the untransmitted signal and the current time is calculated, and the time difference is compared with the preset delay time;
[0084] If the time difference reaches the preset delay time, the untransmitted signal is encoded, and the encoded untransmitted signal and the wireless signal being transmitted at the current moment are transmitted in parallel.
[0085] In this embodiment, each element in the target queue represents a wireless signal to be transmitted, and the elements are arranged in order according to the position of the signal in the queue. Starting from the first element in the target queue, spectrum resources are allocated and the transmission process is started in sequence. After each wireless signal is transmitted, it is removed from the target queue and the target queue state is updated to process the next wireless signal. From the moment the first element in the target queue begins transmission, new wireless signals received within the preset delay time period are constructed into a new queue using the above-mentioned integrated priority and reception time method. The newly obtained queue is spliced after the target queue, completing the dynamic update of the target queue.
[0086] The preset delay duration can be flexibly set based on actual transmission needs. If the time difference reaches or exceeds the preset delay duration, it indicates that parallel transmission is necessary. At this time, the untransmitted signal can be processed, such as encoding and modulation, to ensure that it can maintain signal integrity and accuracy when sharing spectrum resources with the transmitting wireless signal. The system can also adjust transmission parameters such as power and modulation method to ensure that multiple signals do not interfere with each other when sharing spectrum resources.
[0087] This embodiment starts transmitting from the first wireless signal in the target queue in sequence, ensuring that the transmission order of the signals is consistent with their order in the queue, avoiding the problem of signal loss or disorder, and calculating the time difference between the reception time of the untransmitted signal and the current time, so as to understand the waiting time of the signal in real time. When the waiting time of the untransmitted signal reaches the preset delay time, it is transmitted in parallel with the currently transmitted signal, which can make full use of the parallel processing capability of the system. Parallel transmission helps to reduce the waiting time of the signal and improve the throughput and response speed of the system.
[0088] A possible implementation of the embodiment of the present application is to analyze the signal mode and signal type of each wireless signal, including:
[0089] Sampling and quantizing the received target wireless signal to obtain the target wireless signal in the form of a digital signal;
[0090] Extracting features of the target wireless signal to obtain at least one of a time domain feature, a frequency domain feature, and a modulation feature;
[0091] At least one feature is input into a preset recognition model, and the preset recognition model parses and obtains a signal pattern and a signal type of the target wireless signal.
[0092] In this embodiment, the received target wireless signal is first sampled to obtain a discrete time series signal, and the sampled signal is quantized, that is, the amplitude value of the signal is converted into a discrete digital value, thereby obtaining the target wireless signal in the form of a digital signal.
[0093] Furthermore, the target wireless signal is analyzed in the time domain to extract time domain features, including amplitude and phase. A Fourier transform is performed on the digital signal to extract frequency domain features, including spectral distribution and power spectral density. Modulation feature analysis is performed on the numerical signal to extract modulation characteristics, including modulation type and modulation parameters. In practical applications, one or more features can be selected based on actual needs.
[0094] The preset recognition model is pre-built and used to identify the signal pattern and signal type of wireless signals. The model can be based on machine learning or deep learning models. The model training process includes: collecting a large amount of wireless signal data, including samples of different signal patterns and signal types, preprocessing the collected signal samples, extracting features from the preprocessed signal data, using the signal pattern and signal type as labels, and using the extracted features as the training set to train the model to obtain a trained preset recognition model.
[0095] This embodiment samples and quantizes the received target wireless signal and converts it into a digital signal. This helps reduce signal distortion and noise interference during transmission and storage, improves signal quality, and extracts features from the target wireless signal. The features can reflect the basic properties and transmission characteristics of the signal, providing powerful input information for subsequent recognition models. The extracted features are parsed using a preset recognition model to quickly and accurately identify the signal mode and signal type of the wireless signal.
[0096] A possible implementation of the embodiment of the present application is to divide a sub-channel for each signal group from an available frequency band, including:
[0097] allocating initial subchannels for each signal group from an available frequency band based on a signal pattern of each signal group;
[0098] Check whether there is a frequency band intersection between every two initial sub-channels;
[0099] If so, determine the number of wireless signals corresponding to each of the two initial sub-channels with the frequency band intersection, and adjust the two initial sub-channels with the frequency band intersection based on the number of wireless signals to obtain adjusted sub-channels for each signal group.
[0100] In this embodiment, an applicable frequency range can be determined for each signal pattern, with reference to relevant regulations. For any signal group, the frequency band that intersects the applicable frequency range corresponding to the signal pattern of that signal group and the available frequency band is used as the initial subchannel for that signal group. If no two initial subchannels have overlapping frequency bands, the initial subchannel of each signal group is used as the determined subchannel.
[0101] If there are two initial subchannels with overlapping frequency bands, the two initial subchannels are respectively called the first initial subchannel and the second initial subchannel, the first initial subchannel represents a subchannel with a smaller frequency, and the second initial subchannel represents a subchannel with a larger frequency. The intersection frequency band of the first initial subchannel and the second initial subchannel is determined, the number of wireless signals corresponding to the first initial subchannel is called the first number, and the number of wireless signals corresponding to the second initial subchannel is called the second number. Based on the first number and the second number, the intersection frequency band is divided into two parts, respectively called the first part and the second part. The first part is the part with a smaller gap from the first initial subchannel, and the second part has a larger gap from the first initial subchannel. The first part and the first initial subchannel are merged as the adjusted first initial subchannel, and the second part and the second initial subchannel are merged as the adjusted second initial subchannel.
[0102] The minimum value of the first part is the minimum value of the intersection frequency band, and the maximum value of the first part = the first quantity / (the first quantity+the second quantity)×the intersection frequency band+the minimum value of the intersection frequency band. The range corresponding to the first part is obtained, and the remaining part of the intersection frequency band except the first part is used as the second part.
[0103] This embodiment divides the initial sub-channels from the available frequency band according to the signal mode of each signal group, which can ensure that each signal group obtains spectrum resources that match its characteristics. By finding the intersection of frequency bands, potential spectrum conflicts can be discovered and resolved in a timely manner, mutual interference between signals can be avoided, and the quality of signal transmission can be guaranteed. When a frequency band intersection is found, the two initial sub-channels with the intersection are adjusted according to the number of wireless signals corresponding to each other, which can ensure that each signal group can obtain sufficient spectrum resources for transmission.
[0104] In a possible implementation of the embodiment of the present application, the method further includes:
[0105] If the number of wireless signals to be transmitted is one, obtaining an available frequency band and a signal mode of the wireless signal;
[0106] Selecting an applicable frequency band for the wireless signal from available frequency bands based on the signal pattern;
[0107] Determine whether there is a signal being transmitted in the applicable frequency band. If so, obtain the frequency of the wireless signal and determine the superposition method based on the frequency;
[0108] The wireless signal is superimposed on the signal being transmitted in the applicable frequency band by using the superposition method.
[0109] In this embodiment, the intersection of the available frequency band and the applicable frequency range corresponding to the wireless signal's signal pattern is used as the applicable frequency band. If no signal is being transmitted in the applicable frequency band, the wireless signal is transmitted in the applicable frequency band. If a signal is being transmitted in the applicable frequency band, the frequency is compared with a preset frequency threshold. The preset frequency threshold can be flexibly set based on actual experience and is not specifically limited in this embodiment.
[0110] If the wireless signal's frequency exceeds the preset frequency threshold, it indicates that the signal's frequency is high, making frequency division multiplexing suitable. In this case, frequency division multiplexing is selected as the overlay method, and appropriate spectrum allocation and signal processing technologies are prepared. If the wireless signal's frequency does not exceed the preset frequency threshold, it indicates that the signal's frequency is low, making time division multiplexing suitable. In this case, time division multiplexing is selected as the overlay method, and appropriate time slot allocation and signal processing technologies are prepared.
[0111] In this embodiment, when there is only one wireless signal to be transmitted, the most suitable applicable frequency band can be accurately selected from the available frequency bands based on the signal pattern of the signal. If the applicable frequency band is occupied, the superposition method is determined based on the frequency of the wireless signal, and an attempt is made to superimpose the new signal on the signal being transmitted. By simultaneously transmitting multiple signals on the same frequency band, the system's transmission capacity and spectrum efficiency are improved.
[0112] A possible implementation of the embodiment of the present application is to determine the superposition mode based on the frequency, including:
[0113] Compare the frequency with a preset frequency threshold;
[0114] If the frequency exceeds the preset frequency threshold, the frequency division multiplexing mode is determined to be the superposition mode;
[0115] If the frequency does not exceed the preset frequency threshold, the time division multiplexing mode is determined to be the superposition mode.
[0116] This embodiment intelligently selects frequency division multiplexing or time division multiplexing as the superposition method by comparing the frequency of the wireless signal with a preset frequency threshold, thereby ensuring that the most appropriate multiplexing method is selected based on the frequency characteristics of the signal, thereby improving the utilization efficiency of spectrum resources and the quality of signal transmission.
[0117] An embodiment of the present application provides a computer program product, including a computer program. When the computer program is executed by a processor, the contents shown in the aforementioned multimodal wireless signal fusion method embodiment are implemented.
