A Bessel ranging model based on received signal strength (RSSI) is proposed to eliminate the uncertainty of message propagation delay caused by the movement of equipment platform. To make up for the lack of outlier handling in FTSP, an improved iterative reweighted least square (IRLS) method is used to reduce the influence of individual abnormal data caused by unexpected circumstances on the estimated global time. An attack detection mechanism based on the confidence interval of clock deviation is proposed to against continuous malicious attacks. The experimental results show that the improved time synchronization algorithm has higher accuracy and robustness.","PeriodicalId":191106,"journal":{"name":"Proceedings of the 2021 5th International Conference on Electronic Information Technology and Computer Engineering","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122141605","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}

Firstly, this paper constructs a speech enhancement model based on CRN architecture. Convolutional encoder and decoder are used to extract features and recover speech signals, and LSTM modules are used to extract temporal features at the bottleneck of the model. Then a full-scale connection method and multi feature dynamic fusion mechanism are proposed, so that the decoder can make full use of the full-scale features to recover clean speech in the decoding process. Experimental results on TIMIT corpus show that compared with CRN, our FSC-SENet improves PESQ score by 0.39 and STOI score by 2.8% under seen noise cases, and PESQ score by 0.43 and STOI score by 3.1% under unseen noise cases, which proves that the proposed full-scale connection and dynamic feature fusion mechanism can make CRN have better speech enhancement performance.","PeriodicalId":191106,"journal":{"name":"Proceedings of the 2021 5th International Conference on Electronic Information Technology and Computer Engineering","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122544863","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}

High-precision initial alignment technology is an important guarantee for SINS's long-time, long-distance, and high-precision navigation and positioning. Kalman filter, as an important method of the initial fine alignment process, has been widely used in engineering practice. This paper is based on the indirect Kalman filter closed-loop algorithm, in order to make full use of the observation information, multiple iterative operation is performed on the state vector obtained from the Kalman filter feedback correction, and a more accurate state vector prediction result is obtained to reduce the linearization error and then the filter accuracy is improved. The final simulation results show that the proposed method can significantly improve the yaw alignment accuracy under the condition of different small initial yaw misalignment angles, which prove the effectiveness of the proposed algorithm.","PeriodicalId":191106,"journal":{"name":"Proceedings of the 2021 5th International Conference on Electronic Information Technology and Computer Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130036417","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}
