The implementation of the project involves considering the finite word length already at the stage of computation zeros and poles. The results of this stage are final and are not distorted at the stage of structural synthesis. The computation uses the fact that the zeros and poles of a practically implemented digital filter are elements of the set of algebraic numbers of the corresponding degree. At the stage of structural synthesis, a digital filter block diagram is generated. This block diagram provides specified degrees of algebraic numbers, which are zeros and poles. The exact values of the coefficients of the generated digital filter structure are calculated taking into account previously calculated zeros and poles. Different structures are characterized by structural precision, independent of specific coefficient values. This paper is devoted to the study of the generation of structures that provide a given structural precision of the denominator of the transfer function and a given degree of algebraic numbers that are poles.","PeriodicalId":131117,"journal":{"name":"2020 30th International Conference Radioelektronika (RADIOELEKTRONIKA)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122137836","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}

SiON films were deposited using plasma-enhanced chemical vapor deposition (PECVD) system. Thickness, uniformity and refractive index was measured by micro-spot spectroscopic reflectometry and confirmed by ellipsometry. Aluminum (Al) mask was fabricated for etching purpose using lift-off process. SiON films were etched in low pressure inductively coupled plasma - reactive ion etching (ICP-RIE) chamber using CF4 gas. The effect of oxygen (O2) flow rate and source power on etch rate and profile of SiON waveguide was investigated. Scanning electron microscope (SEM) has been used to study the overall structure quality of SiON optical waveguide core. Deposition of SiOx cladding layer was also investigated. SiOx cladding layer was deposited using PECVD system. We investigated the impact of total gas flow rate, N2O/SiH4 ratio and power on the refractive index, growth rate, and uniformity of thickness of the deposited SiOx layer. Micro-trenching occurred in all cases, and their variation was explained by combination of variations in the plasma density and profile angles. The SiO2 cladding layer deposited with N2O/SiH4 ratio of 8,353, total gas flow rate of 1000 sccm and power P = 100W yielded the best results in terms of refractive index.","PeriodicalId":131117,"journal":{"name":"2020 30th International Conference Radioelektronika (RADIOELEKTRONIKA)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127004751","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}

Massive increase of the RAN infastructure complexity creates additional requirements on precise network planning and overall orchestration of the network as such. The possible solution to enhance the statistics feeding the network planning process is to generate massive dataset of the end-user mobility patterns. Unfortunately, we are still constrained with few number of commercialy available datasets, far from the sample statistics needed for machine learning training purposes. Our solution to overcome this problem is to generate additional end user traffic statistics by using generative adversial networks approach. Given the existing sample-constrained end user mobility datasets, GAN network learns to generate new data with the same statistics as the training set. Thus, by leveraging this approach we are able to generate theoretically unlimited samples of realistic end user mobility trajectories. This artificial data jointly with existing limited datasets have the potential to be used for the training blocks of machine learning within the process of the network planning optimization.","PeriodicalId":131117,"journal":{"name":"2020 30th International Conference Radioelektronika (RADIOELEKTRONIKA)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116716472","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}

Exchange of sensitive personal data such as medical information tends to take place frequently throughout the globe; therefore, protecting data from unauthorized adversary access is imperative. Advanced encryption standard (AES) algorithm is one of the algorithms which is broadly employed because of its exemplary security and usage in extensive applications. This research proposes a modified folded pipelined architecture of an AES algorithm for resources constraint applications. The folding transformation controls the circuit functionalities by time-multiplexing operations to a single functional unit and reduces its area considerably. The proposed architecture is implemented using fewer resources, hence, improves area and the power requirements as compared to the conventional algorithm. The work presented in this paper is applicable for encrypting and decrypting personalized Electrocardiograph (ECG) signals for secure transmission. The architecture proposed in this paper reduces the area requirements by 83% and power by 96.8% enabling its hardware implementation more efficient than the conventional AES. Due to its low power and area requirements, the architecture presented in this paper can be used for portable Internet of things (IoT) applications as well.","PeriodicalId":131117,"journal":{"name":"2020 30th International Conference Radioelektronika (RADIOELEKTRONIKA)","volume":"60 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129299640","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}
