The modulation bandwidth of the OLED device is limited to 310 kHz and the signal is generated on carrier frequencies fc = {100, 200, 300} kHz for use across different regions of the OLED frequency response. We demonstrate how setting a specific carrier frequency can affect the system performance. The supported bit rates are 220, 640 and 260 kb/s for fc = 100, 200 and 300 kHz, respectively. The angular dependence of the system performance is also analysed.","PeriodicalId":298711,"journal":{"name":"2016 10th International Symposium on Communication Systems, Networks and Digital Signal Processing (CSNDSP)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114681555","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 study investigates the effect of phase noise on the system Bit Error Rate (BER) for different Output-Back-Off levels in the presence of optical subsystem's nonlinearity in an AWGN channel. Hence, a way to reduce its effect is presented by estimating this phase offset that it is called synchronization of phase noise.","PeriodicalId":298711,"journal":{"name":"2016 10th International Symposium on Communication Systems, Networks and Digital Signal Processing (CSNDSP)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126860368","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}

Applying this tool to any given signal reveals a finite set of oscillatory modes termed intrinsic mode functions (IMFs) and a residual. The sum of all extracted IMFs and the residual reconstructs the original signal without any information loss. Although the EMD satisfies the perfect reconstruction property, it is not based on any optimality criterion. This is an important issue especially in using the EMD for reconstructing the original signal from its noisy versions. At this point, a more flexible form of the EMD is required. Related to this issue, recently, only a few formulations are developed. In addition to these ones, in this paper, a new signal reconstruction algorithm termed time-varying weighted EMD is proposed. This algorithm is optimal in the least-squares error sense and tries to reconstruct the original signal by the sum of time-varying weighted IMFs and residual signal. It is demonstrated by simulations that the proposed algorithm introduces superior performance than that of the existing ones in reconstructing the desired signal after denoising.","PeriodicalId":298711,"journal":{"name":"2016 10th International Symposium on Communication Systems, Networks and Digital Signal Processing (CSNDSP)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134491935","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 rail transportation, WSNs play an important role in real-time monitoring of freight railcars to prevent major failures and derailments. However, the wireless communications among a large number of sensors onboard of a train present unique challenges due to the linear rail network topology, wireless signal interference from locomotives and railcars, and limited power sources available on freight railcars. In this presentation, we discuss a unique two-layer WSN architecture suitable for freight railroads.","PeriodicalId":298711,"journal":{"name":"2016 10th International Symposium on Communication Systems, Networks and Digital Signal Processing (CSNDSP)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114172135","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}

We consider a link of fixed capacity that accommodates Poisson arriving calls of different service-classes with different bandwidth-per-call requirements. Calls compete for the available bandwidth under the MFCR policy. To determine call blocking probabilities, we propose approximate but recursive formulas based on the notion of reserve transition rates. The accuracy of the proposed method is verified through simulation.","PeriodicalId":298711,"journal":{"name":"2016 10th International Symposium on Communication Systems, Networks and Digital Signal Processing (CSNDSP)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129677517","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 solution described in the article is an effective and feasible alternative to minicomputers with the Linux and Python language interpreter. The application of RTOS reduces significantly the required hardware resources, which results in a decrease of the cost of the device and an increase in its energy saving efficiency and reliability. The paper presents the design of an access server that makes remote operation of 16 serial ports possible and that controls 16 power lines via the Ethernet. The device has been developed on the basis of an 8-bit micro-controller equipped with 64 kB of external memory for data and simple power-saving ethernet driver without dedicated processor. Thanks to the application of the operating system the software is composed of a number of tasks running in parallel and being in close communication with one another. With the approach that is compatible with the philosophy of the Internet of Things, there is no need to implement an advanced management panel on the device. This functionality can be implemented in the cloud - on a virtual server.","PeriodicalId":298711,"journal":{"name":"2016 10th International Symposium on Communication Systems, Networks and Digital Signal Processing (CSNDSP)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124013090","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 main point of this paper is to introduce some of the most used Least Mean Squares (LMS) based Finite Impulse Response (FIR) Adaptive Filters and to determine which of them are the most effective under varying circumstances. Experimental results suggest the ideal combination of the chosen settings for these functions. Results of fECG extraction are assessed by Percentage Root-Mean-Square Difference (PRD), input and output Signal to Noise Ratios (SNRs), and Root Mean Square Error (RMSE). Based on simulations conclusions, optimal convergence constant value and filter order were empirically determined. Setting the optimal value of the convergence constant and filter order of adaptive algorithm can be considered a contribution to original results. These results can be used on real records fECG, where it is difficult to determine because of the missing reference.","PeriodicalId":298711,"journal":{"name":"2016 10th International Symposium on Communication Systems, Networks and Digital Signal Processing (CSNDSP)","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134588571","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}
