The Stability of High-Precision Navigation Equipment to Spoofing 高精度导航设备对欺骗的稳定性研究

Recently, high-precision navigation receivers based on precise point position (PPP) and real time kinematic (RTK) algorithms have been widely used. This paper will compare the spoofing immunity of the high-precision PPP algorithm and the standard position estimation algorithm. The PPP algorithm has a good spoofing immunity due to the use of high-precision satellite ephemerides and satellite clocks, compared to the standard positioning algorithm, which receives information about satellite ephemerides and clocks with a broadcast navigation message. If the jammer puts false information about satellites in the signals, according to which the calculated coordinates of the satellites differ very much from the true ones, then there is reason to believe that when using high-precision ephemeris-time information (for example, from the International GNSS Service (IGS) station network), the navigation solution will be blocked, which will protect the receiver from issuing a false navigation solution.","PeriodicalId":262164,"journal":{"name":"2020 22th International Conference on Digital Signal Processing and its Applications (DSPA)","volume":"278 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132457593","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}

Most work in the literature uses full-colour images as the input to the network. In this paper, we show that an edge-based gradient map input can help neural networks in terms of improved accuracy, shorter processing time and training time, especially for small neural networks that fit on low-power consumption platforms. We show that, in comparison to RGB images, gradient map based convolutional neural networks can achieve better accuracy at different scales, and a compressed gradient map network can achieve up to 3.6 times speedup on the inference time while keeping a similar performance. In addition, we show that a gradient map input can also be used for recurrent neural networks to improve lane detection in obscured situations.","PeriodicalId":262164,"journal":{"name":"2020 22th International Conference on Digital Signal Processing and its Applications (DSPA)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124640588","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}

Based on the known relationships describing the direction-finding patterns formed by the antenna array in the direction-finding of narrow-band signals, expressions were obtained in the article for optimal detection of broadband signals. To ensure the possibility of technical implementation of methods in excess of the resolution for the direction-finding of broadband signals, it is proposed in the article for the finite number of frequencies of the broadband signal spectrum to optimally form the direction-finding relief. For the remaining frequencies of the signal spectrum, approximate using various functions. The results of the simulation showed that the more frequencies of the signal spectrum in which the direction-finding relief is formed optimally and the higher the degree of the approximating function, the higher the accuracy of the direction-finding spectrum of the broadband signal. However, this also leads to an increase in hardware and time costs. The main regularities providing formation of the direction finding relief when receiving and processing of broadband signals are derived. Numerical simulation of the obtained regularities is carried out.","PeriodicalId":262164,"journal":{"name":"2020 22th International Conference on Digital Signal Processing and its Applications (DSPA)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122023311","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}

The problems of measuring the amplitude of a discrete harmonic signal (DBS) specified on a finite interval by the method of discrete Fourier transform (DFT) are investigated. To solve the problems of measuring the amplitude of DBS by DFT method, it is proposed to use authors' parametric discrete Fourier transform (DFT-P) which is a generalization of discrete Fourier transform. The theoretical framework for measuring the amplitude of DBS based on DFT-P is developed. The reasons for the non-invariance of the DBS energy spectrum specified on a finite interval in DFT-P basis to the shift of the initial signal are investigated.

Design techniques based on mathematical transformations, a design technique of these cryptographic primitives, have played a particularly important role in the block encryption algorithm known as the Advanced Encryption Standard (AES). Because AES substitution box structure has the best cryptographic properties. However, various weaknesses arise when the implementation attacks are considered. Although the cryptographic properties of substitution box structures based on random selection techniques are worse than the AES substitution box structure, they are more successful to prevent implementation attacks. The aim of this study is to investigate the performance improvement algorithms of substitution boxes based on random selection. In this study, it has been shown that performance improvements of substitution boxes based on random selection can be achieved with the proposed post-processing algorithms. These results are thought to make significant contributions in the future, especially as a countermeasure for the prevention of implementation attacks.","PeriodicalId":262164,"journal":{"name":"2020 22th International Conference on Digital Signal Processing and its Applications (DSPA)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126659282","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}
