The Minkowski and Lollipop DPS has been place in front of and back of the multiband antenna that easily fed by using a 50 Ω microstrip line. The parametric study has been performed to analyze the best range of DPS from the proposed antenna. The simulated and measured impedance bandwidths for 10 dB return loss at first, second and third operating bands can be seen at (135 and 456) MHz, (380 and 272) MHz and (198 and 283) MHz respectively.

Cryptographic post-quantum algorithms have been proposed since 1970s. However, side-channel attack vulnerabilities of these algorithms are still in focus of the recent research. In this paper, we present a differential power analysis attack on the McEliece public-key cryptosystem. We demonstrate that a part of a private key, permutation matrix, can be recovered using the power analysis. We attack a software implementation of a secure bit permutation that was proposed by Strenzke et al. at PQCrypto 2008. The cryptosystem is implemented on a 32-bit ARM based microcontroller. We provide details of the attack and results using power consumption measurements of the device. In addition, we outline a novel countermeasure against the introduced attack. The countermeasure uses properties of the linear codes and does not require large amount of random bits which can be profitable for low-cost embedded devices.","PeriodicalId":159747,"journal":{"name":"2016 26th International Conference Radioelektronika (RADIOELEKTRONIKA)","volume":"1966 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129732900","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 purpose of this indoor positioning system is to search for UWB transmitters in a given area and to determine their position. This article describes not only the hardware design of the UWB receiver but also the FPGA firmware development. The described hardware is also focused on the development of algorithms and creating signal records used during the real positioning system development. The design of our UWB receiver considers many requirements such as wide bandwidth, high ADC sampling rate, high speed digital buses, high speed digital interfaces and being made of low cost parts. The results of our simulations show that UWB receiver we proposed is suitable for this application and the hardware and firmware is able to fulfill our requirements. New functions and new signal processing algorithms can be easily added to the FPGA firmware in the future.","PeriodicalId":159747,"journal":{"name":"2016 26th International Conference Radioelektronika (RADIOELEKTRONIKA)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114333302","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}

One of the challenges are how effectively utilize bandwidth of the transmission media. Wavelength division multiplexing is common used method of multiplexing to create high-speed full-optical networks. Increase of transmission capacity can be achieved by using high-order modulation formats. This paper deals with comparison of bit error rate for the same symbol rate of phase-shift keying and quadrature amplitude modulation technique. The VPIphotonic software was used as a simulation tool. The simulation results show, how high-order modulation formats can increase the transmission capacity and allow better adaptation of transmission signal to transmission channel. Results shows, that quadrature amplitude modulation has better performance in comparison with on/off keying and phase-shift keying modulation.","PeriodicalId":159747,"journal":{"name":"2016 26th International Conference Radioelektronika (RADIOELEKTRONIKA)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133231117","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 model is used for evaluating the influence of the inaccuracies of the obtained reflection and transmission coefficient onto the retrieved permittivity and conductivity. The measured parameters of wool are used while measurement accuracy is emulated by varying number of mesh cells in simulations. The obtained scattering parameters depending on mesh cell number are compared to the ones calculated analytically. It is found that both, measurements and simulations need to be very precise since the textile materials are thin and with low permittivity and losses. The full sensitivity analysis together with comparison of simulations and measurements minimizes probability of errors.","PeriodicalId":159747,"journal":{"name":"2016 26th International Conference Radioelektronika (RADIOELEKTRONIKA)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122008231","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}
