With the increase of temperature, part of the tension of the wire is transferred to the steel core, the stress of the steel core gradually increases, and the stress of the aluminum wire gradually decreases. The stress of steel core decreases with the increase of radial temperature difference, while the stress of aluminum wire increases with the increase of radial temperature difference. Both the overall wire temperature and the radial temperature difference have a greater impact on the stress of the steel core, which reminds researchers to pay more attention to the stress state of the steel core in engineering practice, and provides a reference for maintaining the safe operation of the transmission line.","PeriodicalId":363603,"journal":{"name":"2023 5th International Conference on Electronic Engineering and Informatics (EEI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116090786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes an acquisition algorithm for DSSS signal using traversal method to eliminate non-coherent data modulation. First, dividing the received signal into different frequency intervals, then modifying the local code rates based on the central frequency points of each interval, to prevent the relative slip of received signal and local codes due to long-term integral. Correlating the local codes and each interval signal then putting them into the storage. Doing the FFT operation after eliminating non-coherent data modulation using traversal method then the acquisition result will be captured. This method can adapt to different modulation data rates and signal-to-noise ratios by modifying parameters. Theoretical analysis and simulation results show that the SNR of this paper’ method will higher than the conventional part correlation FFT method 3dB. For modulation data with a rate of 1kbps as an example, this algorithm can adapt to a signal-to-noise ratio of C/N0>44 dB.Hz. This algorithm has good prospects for engineering applications.","PeriodicalId":363603,"journal":{"name":"2023 5th International Conference on Electronic Engineering and Informatics (EEI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124705224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing spoofing detection algorithms, such as snapshot and sequential, can effectively detect some types of spoofing, but their performance in detecting slowly varying spoofing is not ideal. To address this issue, this paper proposes a spoofing detection algorithm based on skewness test. Firstly, this paper established GNSS spoofing model, and obtained the statistical characteristics that the innovation sequence no longer obeys normal distribution under spoofing interference. Based on this, the skewness of the innovation sequence is used to construct test statistics for spoofing detection. Monte Carlo simulations verify the correctness of theoretical analysis, which show that compared with sequential algorithms, the spoofing detection algorithm based on skewness test has prominent advantages of rapid detection and high detection probability, especially when detecting the slowly varying spoofing. This is of great significance for ensuring the reliability of the integrated navigation system positioning.","PeriodicalId":363603,"journal":{"name":"2023 5th International Conference on Electronic Engineering and Informatics (EEI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123308683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So far, there are various methods to predict CSI. However, getting accurate CSI is challenging mainly due to rapid channel variation caused by multi-path fading, and CSI tends to become outdated. The inaccuracy of CSI will have a serious impact on the performance of wireless systems. Channel prediction can reduce the degradation of wireless communication quality caused by outdated CSI. Aiming at this problem, this paper proposes a new predictor, establishes a model combining deep recurrent neural network and attention mechanism, and uses its powerful time series prediction ability, combined with long short-term memory (LSTM) and gated recurrent unit. The performance of the new model is evaluated in terms of prediction accuracy, and the number of neurons with different prediction lengths and different hidden layers is compared. The prediction results show that the model has better prediction accuracy than the performance based on deep recurrent neural network and convolutional long short-term neural network.","PeriodicalId":363603,"journal":{"name":"2023 5th International Conference on Electronic Engineering and Informatics (EEI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129847722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
