[0119] In some embodiments, the second device 102 may refer to a transmitting end in communication interaction, or a communication transmitting device, which can perform data modulation and other processing, and send the processed signal or information to the receiving end. The first device 101 may refer to a receiving end in communication interaction, or a communication receiving device, which can receive the signal or information sent by the second device 102, and can demodulate the data in the signal or information to obtain the interactive data.

[0131] In some implementations, to meet the service demands of mobile communication systems such as 5G or future 6G, including high-speed data transmission, massive bandwidth, and reliable communication in mobile scenarios, and to realize future wireless communication visions such as smart cities and smart transportation, current wireless communication networks still need improvement and enhancement in many aspects. Among these, accurate data demodulation is one of the fundamental modules for achieving low bit error rate and high-speed transmission in wireless communication systems, and it affects the overall performance of the communication system.
[0132] In some implementations, the demodulator is derived using methods derived from the Neyman-Pearson theorem and Bayes' theorem. Such demodulators typically require accurate channel state information and channel noise distribution, and their performance depends on the parameter settings of individual modules, such as filters, phase-locked loops, product modulators, or analog-to-digital converters. These demodulators may exhibit the following characteristics:
[0133] (1) It has a large time delay and is complex to implement.
[0134] (2) Unstable module performance: Due to factors such as vibration, acceleration, temperature fluctuation, aging, and instability of discrete components, the module performance will change, resulting in a decline in the overall performance of the receiver.
[0135] (3) Poor environmental adaptability: Wireless communication channels may suffer from undesirable factors such as multipath fading, impulse noise, clutter, or discrete interference, which significantly reduces demodulation accuracy. For example, some coherent demodulators require carrier synchronization, and the phase error and frequency offset present during the synchronization process will cause significant demodulation errors.
[0136] (4) It relies heavily on prior knowledge such as channel state information (CSI), but in communication, such as in fast fading scenarios, it is difficult to accurately estimate CSI. Therefore, the channel model may be unknown at the receiver.
[0137] (5) Prior waveform information and time series information were not fully utilized.
[0138] In some implementations, the increasing demand for wireless services such as smartphones, virtual reality, and the Internet of Things necessitates handling more complex and diverse communication requirements. Demodulators or mathematical models designed according to rigorous mathematical theory and precise system models may not be adequate for these needs. Therefore, AI or ML technologies, such as deep learning, can be applied to wireless communication systems.
[0139] In some implementations, the information of the modulated signal is represented by amplitude and phase. A crucial step in signal demodulation is feature extraction. Deep learning-based demodulators (or learning-based demodulators) can utilize neural networks to autonomously learn and extract important feature information from the received signal, thereby achieving data demodulation with higher accuracy and robustness. Deep learning-based demodulators include the following characteristics:
[0140] (1) Model training is performed using a dataset of a certain size under specific channel environment and parameter configuration. The demodulation model obtained under this environment and configuration has good flexibility and adaptability, which is conducive to improving the data demodulation accuracy.
[0141] (2) During the training process, the model can learn the data distribution characteristics under various undesirable conditions. Therefore, the demodulator based on deep learning has stronger anti-noise and anti-interference capabilities.
[0142] (3) The requirements for prior knowledge (such as CSI and channel noise) can be relaxed or even eliminated.
[0143] Therefore, deep learning-based demodulators have great potential in dealing with complex wireless communication environments and improving communication performance.
[0144] In some implementations, the mapping between the raw data (data to be modulated) and constellation symbols differs depending on the modulation scheme, such as Quadrature Phase Shift Keying (QPSK), 16-Quadrature Amplitude Modulation (16QAM), or 64-Quadrature Amplitude Modulation (64QAM). At the receiver, one data symbol to be demodulated can correspond to data bits of different lengths. Therefore, for received data symbols using different modulation schemes, a matching demodulation scheme is required for data demodulation. Similarly, in AI-based demodulation implementations, different modulation schemes must also be considered.
[0145] In some implementations, training the AI model requires input and output data of a defined dimension. The length of the demodulated data corresponding to a single data symbol differs depending on the modulation scheme. For example, in 16QAM modulation, a constellation point corresponds to 4 bits of data, while in 64QAM modulation, a constellation point corresponds to 6 bits of data. Therefore, the AI demodulation model used for 16QAM modulation outputs 4 bits of data, and the AI demodulation model used for 64QAM modulation outputs 6 bits of data. Consequently, the two models need to learn the mapping relationship between constellation points and data for each modulation scheme.
[0146] In one embodiment shown in Figure 1B, if the receiving end knows the modulation scheme information, for example, the modulation scheme information is indicated to the receiving end by the transmitting end during data transmission, the receiving end uses the modulation scheme information as auxiliary information for selecting the demodulation model, and the AI-based demodulation model realizes data demodulation under different modulation schemes.
[0147] In conjunction with another implementation shown in Figure 1C, when the transmitting end does not indicate modulation mode information, the data to be demodulated and the corresponding modulation mode information can be used as training data to train an AI modulation mode recognition model. This recognition model can determine the modulation mode of the corresponding transmitting end signal based on the features of the data to be demodulated, and then select the AI demodulation model under the corresponding modulation mode for data demodulation.
[0148] In some implementations, the main application process of deep learning-based data demodulation is as follows: Model training is performed on an AI network model, such as an AI demodulation model, used for data demodulation. After model training is completed, the trained AI demodulation model is deployed on the signal receiving device, where model inference can be performed to complete the data demodulation task at the receiving end of the actual system.
[0149] In some implementations, different AI demodulation models are typically required because the mapping relationship between the data symbols to be demodulated and the demodulated data differs under different modulation schemes. For a given modulation scheme, one model can be used to implement data demodulation. However, due to device movement, changes in channel conditions, and the instability of the wireless environment, the distribution of the data to be demodulated input to the AI demodulation model during inference applications may change significantly. In other words, the distribution of input data during model application differs from the distribution of input data during model training. This may cause the input-output mapping relationship learned by the AI demodulation model based on the training dataset to no longer be entirely suitable for the test data, resulting in a decrease in the performance of the AI demodulation model and a reduction in the generalization ability of the AI model.
[0150] In some implementations, to improve the generalization problem of AI models in wireless communication system applications, the following three enhancement methods can be used to ensure the relative stability of the demodulation model's accuracy:
[0151] (1) Train a model using mixed datasets under different environments or configurations;
[0152] (2) Update the model using real-time data collected during the model application process;
[0153] (3) Train multiple models for different environments or configurations and select the appropriate model for inference during model application.
[0154] Referring to Figure 1D, during model updates, the training dataset collected under environment parameter i can be used to complete model training. When applying the model under environment parameter j, the training dataset collected under environment parameter j is used first to update the model, and then the updated model is used for model inference to complete data demodulation.
[0155] In some implementations, model training consumes more computational resources than model inference. Therefore, model updates require devices with high hardware computing resources to support low-latency online model training. Model updates require a certain number of ideally labeled data samples. However, data collection during model application incurs significant data collection costs and introduces latency, impacting the real-time performance of the model.
[0156] For data demodulation, the dataset used for AI demodulation model updates includes: model input (such as the data to be demodulated) and model target output (such as the original transmitted data). The data to be demodulated can be directly obtained by the receiver based on the received signal. However, due to real-time data transmission errors, the model target output is difficult for the receiver to obtain, such as ideal label data samples for model updates. Optionally, to address the generalization problem of AI-based data demodulation models, model updates are used to ensure model performance. However, model updates require a certain number of ideal label data samples, which are difficult to obtain in real-time model applications, thus posing challenges to model updates.
[0157] Figure 2A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the present disclosure relates to a communication method, which includes:
[0158] In step S2101, the first device 101 determines or selects training samples.
[0159] In some embodiments, the first device 101 may select training samples in accordance with the manner defined by the protocol or the principles of pre-configuration.
[0160] In some embodiments, the first device 101 may be a terminal or a network device. For example, the terminal or network device selects one or more sets of training samples for demodulating model training or model updating.
[0161] Optionally, the demodulation model can be an AI or ML-based model used to demodulate the model's input and output the demodulated information.
[0162] Optionally, the demodulation model can be deployed at the receiving end, such as the first device 101, for example, in a terminal and / or network device, to demodulate the received data.
[0163] Optionally, model training can include offline training or online training. Offline training can be based on a pre-collected dataset to train the demodulation model. Online training can be based on a dataset collected in real-time or near real-time to train the demodulation model.
[0164] Optionally, model updating can involve continuing online training of a pre-trained or trained demodulation model, thereby updating the model parameters of the pre-trained demodulation model. These model parameters can include the structure and weight parameters of the demodulation model. Model updating or online model training allows the demodulation model to better adapt to different environmental characteristics or channel environments, improving the model's generalization ability.
[0165] In some embodiments, training samples may refer to training datasets used to train or update demodulation models.
[0166] In some embodiments, the input to the demodulation model is the data to be demodulated, and the output is the demodulated data. When training the demodulation model, the training samples may include input training samples and output training samples.
[0167] Optionally, the input training samples can be based on the demodulated data received through communication, and the output training samples can be indicated by the first information.
[0168] In some embodiments, the training samples include:
[0169] One or more target data (Data);
[0170] Optionally, the target data can be the output training samples of the demodulation model, used for training or updating the demodulation model. In some embodiments, the target data satisfies at least one of the following:
[0171] Generated based on a predefined method;
[0172] Use a predefined data sequence.
[0173] Optionally, the target data is generated based on a predefined protocol method, for example, the first device 101 generates one or more target data in a random manner.
[0174] Optionally, the target data can use a predefined data sequence. For example, one or more target data can use a simple data sequence, such as Data1 using an all-zero sequence and Data2 using an all-one sequence.
[0175] In some embodiments, the target data can be used as data dedicated to demodulation model training or updating. Training with a simple data sequence can reduce processing operations at the sending or receiving end and reduce interference from the channel environment on the target data transmission.
[0176] In some embodiments, terms such as "certain," "preset," "default," "set," "indicated," "a certain," "any," and "first" can be used interchangeably. "Certain A," "preset A," "default A," "set A," "indicated A," "a certain A," "any A," and "first A" can be interpreted as A pre-defined in a protocol or the like, or as A obtained through setting, configuration, or instruction, or as specific A, a certain A, any A, or first A, but are not limited thereto.
[0177] In step S2102, the first device 101 sends the first information to the second device 102.
[0178] In some embodiments, the second device 102 may be a terminal or a network device. For example, the first device 101 may be a terminal and the second device 102 may be a network device; or, the first device 101 may be a network device and the second device 102 may be a terminal. As another example, the first device 101 and the second device 102 may be different terminals or different network devices.
[0179] In some embodiments, the first information may be indication information, or an indication carried in indication information, auxiliary information, or configuration information.
[0180] Optionally, when the first device 101 is a terminal and the second device 102 is a network device, the first information can be sent via Radio Resource Control (RRC) messages.
[0181] Optionally, when the first device 101 is a network device and the second device 102 is a terminal, the first information can be sent via downlink control information (DCI) or RRC messages.
[0182] In some embodiments, the first information includes training samples used to train or model the demodulation model. The description of the training samples can be found in the description of step S2101, such as including one or more target data.
[0183] Optionally, the target data can be the output training samples of the demodulation model, and the first information can indicate the content of one or more target data.
[0184] In some embodiments, the first information may further include the number (n) of target data.
[0185] Optionally, the amount of target data can be based on protocol definition, terminal determination, or network device configuration. The amount of target data can be indicated in the first information.
[0186] Optionally, the amount of target data can be used to measure the number of training samples, or to verify the amount of target data received that matches the amount of target data received.
[0187] In one example, the first information includes the number of target data points, n, and the training samples, such as one or more target data points, for example, Data. i , where i = 1, 2, ..., n.
[0188] In this example, the first device 101 and / or the second device 102 can easily determine the data used for model training or updating. For example, referring to the description of step S2103, if the second device 102 sends information modulated on the target data, the first device 101 can determine whether the second information has been completely sent, i.e., whether the modulation information corresponding to the target data has been completely sent, based on the reception of the first information. Thus, the first device 101 can perform training or updating in a timely manner. As another example, if the second information also includes other data, or if there is other information sent synchronously with the second information, the first device 101 can receive a corresponding amount of second information (including information modulated on the target data) based on the quantity of target data.
[0189] In another example, the first information includes the target data, such as Data. i Where i = 1, 2, ..., n, the number of target data n can be determined by the device performing training or updating, such as by the first device 101. For example, in conjunction with the description of step S2103, if the second device 102 sends information modulated on the target data, the first device 101 can determine the number of second information used for training or updating, that is, the number of modulation information corresponding to the target data.
[0190] In some embodiments, the second device 102 receives first information to obtain target data for demodulating model training or updating.
[0191] It is worth noting that, in conjunction with the description of the foregoing embodiments, due to changes in device location, channel environment, or configuration, real-time data transmission may contain errors. The first device 101, relying solely on demodulation of the received information, may struggle to obtain ideal output training samples. However, based on the first information of this embodiment, the first device 101 and the second device 102 can determine the training samples, such as target data, for model training or updating before model training or updating. This ensures that the demodulated model has ideal output labels during training or updating, thereby improving the accuracy of model training or updating.
[0192] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", and "field" can be used interchangeably.
[0193] In some embodiments, terms such as “send,” “transmit,” “report,” “distribute,” “transmit,” “bidirectional transmission,” “send and / or receive” can be used interchangeably.
[0194] In some embodiments, the terms “downlink control information (DCI),” “downlink (DL) assignment,” “DL DCI,” “uplink (UL) grant,” and “UL DCI” can be used interchangeably.
[0195] In some embodiments, "acquire," "get," "obtain," "receive," "transmit," "bidirectional transmission," and "send and / or receive" can be used interchangeably and can be interpreted as receiving from other entities, acquiring from protocols, acquiring from higher layers, obtaining through self-processing, or autonomous implementation. Protocols include, for example, at least one of the 3GPP protocol, Wi-Fi protocol, and audio and / or video protocols.
[0196] In step S2103, the second device 102 sends the second information to the first device 101.
[0197] In some embodiments, the second information is information sent during the model training or update phase of the demodulation model.
[0198] In some embodiments, the second information includes information modulated on the target data, used to carry data related to demodulation model training.
[0199] In some embodiments, the second information may be transmission information or transmission signal, which is modulation information in model training or updating.
[0200] In some embodiments, after obtaining the first information, the second device 102 learns the target data specifically used for demodulating model training or updating.
[0201] In some embodiments, during the model update process, the second device 102 uses the target data as the original transmission data, such as preprocessing and modulation of the target data to obtain modulated data, and carries the modulated information of the target data through the second information carrier, such as the modulated data.
[0202] In some embodiments, the second device 102 may transmit the second information under different conditions. These conditions include channel environment and / or channel parameter configuration.
[0203] For example, the second device 102 transmits the second information multiple times under different conditions. Each transmission of the second information corresponds to a condition, such as a channel environment or a channel parameter configuration.
[0204] Optionally, the target data involved in the second information transmitted under different conditions may be the same or different, or the target data corresponding to different second information may be the same or different. For example, it may include information modulated from the same or different target data. Thus, based on a limited number of target data, more input training samples can be obtained, for example, in conjunction with the description of step S2104, the first device 101 can obtain more input in model training or updating.
[0205] Optionally, the second information transmitted under different conditions may include information modulated from the same target data. Thus, based on the same target data, and combined with variations in conditions such as channel environment and / or channel parameter configuration, multiple input training samples can be obtained.
[0206] In one example, taking the same target data corresponding to different second information as an example, the second device 102 can send the second information multiple times under different channel environments and / or different channel parameter configurations. Each second information includes information modulated on the same target data. Under different conditions, each second information transmitted through the channel will be different.
[0207] For example, the second information includes information modulated from Data1. The second device 102 can transmit this second information multiple times under different channel environments. For instance, the second device 102 can transmit the second information under channel environments with certain physical characteristics, such as indoors, outdoors, at a set altitude, or at a set latitude and longitude. In these different channel environments, Data1 remains unchanged, but the information modulated from Data1 changes during transmission, resulting in different demodulated data obtained by the first device 101, i.e., different input training samples.
[0208] For example, the second information includes information modulated from Data1. The second device 102 can transmit this second information multiple times under different channel parameter configurations. For instance, in an indoor channel environment, the second device 102 can transmit the second information multiple times, adjusting one or more environmental or channel parameter configurations each time it transmits the second information. In this case, Data1 remains unchanged under different parameter configurations, but the information modulated from Data1 changes during transmission, resulting in different demodulated data obtained by the first device 101, i.e., different input training samples.
[0209] In this example, by changing the channel environment or channel parameter configuration, the same target data can obtain multiple different input training samples, thereby using a limited amount of target data and saving signaling resources for the first information.
[0210] In some embodiments, the second device 102 may send N second messages under the same or different conditions, where N is the number of target data; wherein each of the N second messages includes information modulated on a target data.
[0211] In one example, the second device 102 sends N second messages, wherein the first second message includes information modulated onto Data1, the second second message includes information modulated onto Data2, ..., and the Nth second message includes information modulated onto Data1. n The modulated information.
[0212] In some embodiments, the n target data can be repeatedly sent in the manner described in the above example, such as repeatedly sending one or more of the n target data, or repeatedly sending the n target data N times, to obtain n*N training samples.
[0213] In some embodiments, the first device 101 receives second information.
[0214] In step S2104, the first device 101 determines the input of the demodulation model based on the second information, and trains or updates the demodulation model using the target data as the target output.
[0215] In some embodiments, after receiving the second information, the first device 101 may perform preprocessing such as equalization or detection on the second information to obtain the data to be demodulated in the second information.
[0216] Optionally, the data to be demodulated can be information such as constellation symbols.
[0217] In some embodiments, the input to the demodulation model can be the aforementioned data to be demodulated, or the input training samples can be the aforementioned data to be demodulated. Based on the demodulation model, the output is the demodulated data from the training or update phase.
[0218] Optionally, the demodulated data is either soft bit data to be decoded of the log-likelihood ratio type or the original bit data corresponding to the target data.
[0219] In some embodiments, the target data (Data) is used at the transmitting end to obtain modulated data and at the receiving end to serve as the target output for training or updating the demodulation model in order to adjust the output accuracy of the demodulation model.
[0220] In some embodiments, if the second device 102 sends the second information under different conditions or sends the second information multiple times, for example, the target data corresponding to the different second information sent multiple times may be the same or different.
[0221] Optionally, the first device 101 can receive second information under different conditions. Due to changes in the channel environment and / or channel parameter configuration, the first device 101 can obtain different data to be demodulated each time it receives second information, thereby obtaining more input training samples.
[0222] In some embodiments, training or updating of the demodulation model may be stopped when any of the following conditions are met:
[0223] The training or update time reaches a first duration, which can be defined by the protocol or determined by the first device 101 and the second device 102;
[0224] The number of iterations for training or updating the demodulation model reaches a predetermined number, which can be defined by the protocol or determined by the first device 101 and the second device 102;
[0225] The trained or updated demodulation model has reached a convergence metric, such as the output of the demodulation model meeting a predefined performance metric.
[0226] Optionally, the predefined performance metrics include, but are not limited to, a predefined error, which indicates that the training or update of the demodulation model is complete when the error between the output of the demodulation model and the ideal target output (such as target data) is less than or equal to the predefined error.
[0227] Optionally, if any of the above conditions are met, the training or update of the demodulation model is considered complete, and inference or application can be performed based on the demodulation model.
[0228] In step S2105, the second device 102 sends third information to the first device 101.
[0229] In some embodiments, the third information is information sent during the model inference or application phase of the demodulation model.
[0230] In some embodiments, the third information includes information modulated from the communication data. The communication data represents data that needs to be transmitted or demodulated by the first device 101 in actual communication.
[0231] Optionally, the third information may be modulation information in model inference or application.
[0232] In some embodiments, third information can be used to determine the actual input to the demodulation model in model inference or application.
[0233] In some embodiments, the first device 101 receives the aforementioned third information.
[0234] In step S2106, the first device 101 determines the demodulation data based on the trained or updated demodulation model and the third information.
[0235] In some embodiments, the first device 101 may perform preprocessing such as equalization or detection on the received third information to obtain the communication data to be demodulated in the third information.
[0236] In some embodiments, the communication data to be demodulated is taken as input, and the demodulated data corresponding to the communication data is output using the demodulation model.
[0237] In some embodiments, the demodulation model trained or updated by the model has good generalization and robustness and can accurately obtain demodulated data.
[0238] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2106.
[0239] For example, step S2102 can be implemented as an independent embodiment, steps S2102 to S2104 can be implemented as an independent embodiment, and steps S2102, S2105 to S2106 can be implemented as an independent embodiment, but are not limited thereto.

[0288] Figure 4 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 4, the communication method involved in this embodiment of the present disclosure includes:
[0289] Step S4101: Data interaction between the receiving end and the sending end for model update.
[0290] In some embodiments, the transceiver devices perform data information exchange for AI demodulation model updates: that is, the sender or receiver selects one or more sets of data for AI demodulation model performance updates and sends an indicator to the other party.
[0291] Optionally, the indicator includes the number of data samples n used for model updates, and the data sample Data per data point. i Let i = 1, 2, ..., n. If model updates are required during model application, they will be performed based on this set of data; this set of data can be randomly generated or use simple data sequences such as all 0s or all 1s.
[0292] The main purpose of this step is to determine the data specifically used for model updates during subsequent model applications, similar to the pilot data used in channel transmission and reception. In this way, during model updates, the transmitter uses this data as the original transmission data, and the receiver uses it as the target output for model training, thus achieving model updates.
[0293] In some embodiments, the receiving end corresponds to the first device 101 in the foregoing embodiments, and the sending end corresponds to the second device in the foregoing embodiments.
[0294] In some embodiments, the Indicator corresponds to the first information in the foregoing embodiments.
[0295] In some embodiments, step S4101 corresponds to step S2102 or step S2202 in the foregoing embodiments.
[0296] In step S4102, the transmitting end completes data modulation and other processing.
[0297] In some embodiments, the transmitting end uses the Data for model performance monitoring determined in step S4101 as the original transmission data, completes data modulation and other processing, and generates a data signal to be transmitted.
[0298] In some embodiments, the data signal to be transmitted corresponds to the second information in the foregoing embodiments.
[0299] Step S4103: The sending end transmits real-time data for model updating to the receiving end.
[0300] In some embodiments, data transmission can be performed in this step, such as the sending end sending the data signal to be transmitted to the receiving end.
[0301] In some embodiments, the real-time data corresponds to the second information used in the model training or update process in the foregoing embodiments.
[0302] In step S4104, the receiving end completes data demodulation and other processing.
[0303] In some embodiments, the receiving end acquires the received signal and acquires the data to be demodulated.
[0304] Step S4105: The receiving end updates the AI demodulation model.
[0305] In some embodiments, due to real-time changes in the channel environment, the same original transmitted data will result in different demodulated data received by the receiver after channel transmission. Therefore, the transmitter can repeatedly transmit n sample data, and the receiver can reuse the data for model updates. The receiver processes the received signal to obtain the demodulated data. The model is updated by using the data to be demodulated as input to the AI demodulation model and using the data used for model updating as the target output.
[0306] In some embodiments, step S4105 corresponds to step S2104 or S2204 in the foregoing embodiments.
[0307] Step S4106: The sending end transmits real-time data to the receiving end.
[0308] In some embodiments, step S4106 corresponds to step S2105 or S2205 in the foregoing embodiments.
[0309] Step S4107: The receiving end performs real-time data demodulation.
[0310] In some embodiments, the receiving end completes subsequent real-time data demodulation based on the updated AI demodulation model.
[0311] In some embodiments, step S4107 corresponds to step S2106 or S2206 in the foregoing embodiments.
[0312] In some embodiments of this disclosure, when the application environment or parameter configuration of the AI-based data demodulation model differs from that during model training in actual system applications, it is necessary to consider the generalization ability of the AI demodulation model and apply common generalization enhancement methods to ensure model application performance. Model updating is a common method to enhance the generalization ability of AI models, and ideal label data collection is a key step in the model updating process. It is necessary to clarify the data collection methods used for updating the AI demodulation model in the actual system to effectively update the model and ensure its stable operation.
[0313] In some embodiments, the method of this disclosure, which is a method for using model updates to ensure the generalization of AI demodulation models, can be used for data collection for AI demodulation model updates, effectively obtaining ideal label data for model updates, enabling the model to process real-time data under actual application environments or parameter configurations, thereby ensuring better AI demodulation model performance.
[0314] In some embodiments, for data transmission in a real communication system, the original data from the transmitting end is transmitted to the receiving end via a wireless channel after modulation and other steps. Due to factors such as channel noise and non-ideal device characteristics, the data obtained by the receiving end after demodulation and other steps has a certain error compared to the original data sent by the transmitting end. Updating the AI demodulation model requires ideal tag data, including the data to be demodulated and the corresponding ideal demodulation data. In conventional signal transmission and reception processes, ideal demodulation data is difficult to obtain. The method of this disclosure can be used as a data collection method for AI demodulation model updates, enabling the receiving end to obtain ideal demodulation data corresponding to the data to be demodulated and identical to the original data sent by the transmitting end for AI demodulation model updates.
[0315] In some embodiments, the method of this disclosure can effectively obtain ideal label data for model updates, enabling the model to process real-time data under actual application environments or parameter configurations, thereby ensuring better AI demodulation model performance.
[0316] In some embodiments, the present disclosure can address the generalization problem of AI demodulation models in actual system applications, realize data collection for model updates during model system applications, help achieve efficient AI demodulation model updates to ensure the demodulation accuracy of AI demodulation model data, and thus effectively improve the practicality of AI-based demodulation schemes.
