It has the advantages of fast operation time, high verification accuracy, and no need for specific structural parameters of the accelerator head for modeling. However, it is often necessary to establish a ray coordinate system for each ray and divide the cylinder string area in the ray coordinate system, which makes the algorithm involve multi coordinate system conversion and other issues. In this paper, a CCC algorithm in a unified coordinate system is proposed to solve this problem. On the premise of not affecting the verification accuracy, the affected points and their outer point coordinates are used to divide the cylinder string area, avoiding the problem of coordinate conversion in multiple coordinate systems, and simplifying the algorithm modeling process.","PeriodicalId":330562,"journal":{"name":"2022 14th International Conference on Signal Processing Systems (ICSPS)","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132941313","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}

But OTFS integrated signal has high Peak to Average Power Ratio (PAPR), which degrades the performance of the system heavily. In this paper, the PAPR characteristics of OTFS signals are firstly deduced and evaluated, then a hybrid PAPR reduction algorithm is proposed. It is based on Zadoff-Chu Matrix Transform (ZCMT) and Partial Transmit Sequences (PTS) for reducing P APR. Firstly, an orthogonal precoding matrix is constructed using the Zadoff-Chu sequence, then the data symbols are multiplied by the precoding matrix, and then OTFS signal is divided using the conventional PTS procedure. Finally, the optimal phase rotation factor is selected to reduce the autocorrelation of each sub-data block of the OTFS integrated signal, thus a low P APR OTFS integrated signal is obtained. The simulation results show that the algorithm achieves better P APR suppression performance.","PeriodicalId":330562,"journal":{"name":"2022 14th International Conference on Signal Processing Systems (ICSPS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128700576","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}

Considering the environment of the ship equipment, based on the scientific theory of open complex giant system, the reliability analysis of the ship equipment as an open complex giant system is carried out, and the multi-element coupling model of“ one subject four elements“ system is established. To analyze the health status of multi-attribute ship equipment system, the system reveals the coupling effect and influence of equipment attributes, environmental factors, maintenance intervention and other equipment multi-element on the health evolution of a complex equipment. By improving the traditional DEMATEL-ANP method, the established system multi-element coupling relationship matrix is introduced to replace the direct impact matrix, and the equipment attributes, environmental factors Conduct quantitative evaluation on the coupling effect and impact of maintenance intervention and other equipment multi factors on the health evolution of a certain equipment. Through experimental verification, it can be seen that the proposed system multi-element coupling model and the improved method can quickly and accurately analyze the coupling relationship and influence among the various elements of the marine engine system, and at the same time, it can quantitatively evaluate the impact in time to determine the key elements.","PeriodicalId":330562,"journal":{"name":"2022 14th International Conference on Signal Processing Systems (ICSPS)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115396615","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}

In this method, the selection of quantization algorithm in the quantization stage is particularly important. The poor performance of the initial key will affect the efficiency of key reconciliation, and even cause the failure of the whole key generation method. In the existing quantization algorithms, the quantization level and guard interval are fixed, so the performance of the initial key cannot always be optimized in the face of complex and changeable communication environment. Aiming at the above problems, this paper combines the adaptive adjustment of quantization level and guard interval effectively on the basis of existing multi-bit quantization algorithm. This method continues the method of deleting eigenvalues by index value in multi-bit quantization algorithm, which improves the consistency of initial key. Based on information theory, this method selects optimal quantization level on the premise that the initial key is theoretically error-free under different SNR. This method sets the guard interval based on the average error probability of the eigenvalue and the quantization level, which solves the problem of deleting too many eigenvalues when the SNR is high in the method of setting fixed guard interval. Simulation results show that this method is feasible.","PeriodicalId":330562,"journal":{"name":"2022 14th International Conference on Signal Processing Systems (ICSPS)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127486301","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 non-uniform non-stationary and non-Gaussian clutter degrades the performance of traditional power-based threshold detection methods based on the statistical signal processing theory. Most recent works on the feature-based target detection methods relies on the time-frequency features, which may be unavailable for short-dwell-time applications. Therefore, this work develops a new multi-dimensional feature of targets, multi-circle feature, without limitation of the dwell-time length. A convolutional neural network (CNN) is employed to discriminate true targets and false alarms after the low-threshold detection in energy domain. The experimental results exhibit that the proposed CNN-based detection can achieve a nearly 80% reduction in false-alarm rate without the loss in detection rate compared to the traditional threshold detection.","PeriodicalId":330562,"journal":{"name":"2022 14th International Conference on Signal Processing Systems (ICSPS)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126372366","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}

For active noise reduction earphones, disturbance and uncertainty of the secondary path will be caused if the tightness or direction of the earphones changes. Therefore, it is necessary to measure several secondary paths to obtain one nominal secondary path before designing controllers, and the constrain on the stability of the feedback system should be made to ensure the robustness of the system. In this paper, improvements are made on the selection of nominal secondary path and disturbance weighting function on the basis of robust control theory. The optimized method makes it possible to achieve higher noise reduction on the premise of ensuring the stability of the feedback system. The robustness of feedback system is improved, and the maximum disturbance to noise reduction performance is reduced.","PeriodicalId":330562,"journal":{"name":"2022 14th International Conference on Signal Processing Systems (ICSPS)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121865231","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}
