This article discusses different methods of introducing watermarks: into the spatial domain and the transformation domain. The attacks in this case are filters that can be applied to images: blurring, adding noise, sharpness, contrast, color balance. Methods have been identified that allow you to determine with higher accuracy the specific type of attack on the embedded digital watermark in the image. The peculiarity of this method is that the original image does not need to be used to determine the attack (blind method [1]).","PeriodicalId":267775,"journal":{"name":"2021 Wave Electronics and its Application in Information and Telecommunication Systems (WECONF)","volume":"204 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116180908","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 telecommunication systems voice messages are transmitted over wired and wireless communication channels using analog and digital signals. The types of voice signal transmission implementations depend on their purpose, propagation conditions, and a set of factors that must be taken into account when designing and building communication networks. Communication systems on the railway transport is used, the device is designed to provide internal and external communications. Operation of communication systems is carried out taking into account certain technical features: the presence of vibration, increased requirements for reliability and reliability of connections.

The method has a number of side effects, including deformation of the forms of the total and difference antenna patterns, as well as the forms of the direction finding characteristic and its inverse function. The presence of inaccuracies and distortions in the formation of the amplitude-phase distribution of both the main and compensating antennas leads to a decrease in the efficiency of the compensation method, to additional distortions of the antenna characteristics. The work is devoted to estimating the impact of these inaccuracies and distortions of compensating antenna on the performance of the antenna array and developing accuracy requirements.","PeriodicalId":267775,"journal":{"name":"2021 Wave Electronics and its Application in Information and Telecommunication Systems (WECONF)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133101017","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}
