For the direct case, the numerical process does not use any integral calculations as it appears in the definitions of the harmonic coefficients used in the classic and well-known Fourier series approach. For the reciprocal case, by using a small number of rectangular digital signals generated with the technique introduced in the first case, we can achieve an accurate precision in the process of convergence for the generation of an analog communication signal, by assuming an arbitrary AC signal as our reference. As a direct application, we introduce an efficient process that can be used for a wide class of digital modulations that have technological demand and are widely used by many electronic designers. To demonstrate some experimental results, we present the first architecture designed to check the original electromagnetic approach introduced in this paper with some experimental measurements. Recent advancements of this research have been performed constantly to check the efficiency of technological approach, with a set of consistent laboratorial measures which permit us to visualize the expressive reduction of the transmission rates for those digital systems that demand a high speed for their processing in the real time.","PeriodicalId":177579,"journal":{"name":"2018 New Trends in Signal Processing (NTSP)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124532087","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}

An autonomous platform can be directed by the operator to perform specified tasks with assumed accuracy, without the need to continuously control the behavior of the platform. This paper contains the accuracy analysis for operator tracking tasks with a wireless ultra wide band system. These tasks are investigated through simulation and field measurements. Four stationary transmitters are placed on an unmanned ground vehicle. A mobile transmitter, mounted on a tripod, is used for position marking. The vehicle remained stationary, while the transmitter was moved across a known route over the field. Positions of a transmitter in the horizontal plane are determined and compared with the designated route. Location distribution for several real positions is shown. Real measurements with simulated are compared. Indoor measurements are also performed. Results have shown that tested ultra wide band system has a linear error of a maximum of 0.5 m at distance of 10 m, which is sufficient for use in an unmanned vehicle tracking system.","PeriodicalId":177579,"journal":{"name":"2018 New Trends in Signal Processing (NTSP)","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114155673","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}

Some relationship between a set of digital pulses and a special class of the real polynomials, allow us to identify the generation of a single pulse with an intrinsic dependence with the zero values of an arbitrary equation represented by a polynomial equation, where this direct match is established through an analytic operator. By using an ordinary Field Programmable Gate Array architecture, it is possible to validate our theoretical approach, and we are presenting some experimental measurements, as well as one application on how to build a commercial data compressor for fiber optics. The algorithm here introduced presents an innovative technique, and it performance is faster per comparison. Furthermore, thanks to the math-to-time domain transformations, it tends to overcome the current time required to process polynomial equations, which are involved in the data compression and data encryption systems.","PeriodicalId":177579,"journal":{"name":"2018 New Trends in Signal Processing (NTSP)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129464137","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}
