Multiple techniques have been proposed in the literature in order to mitigate asynchronous impulsive noise to enable PLC, e.g., in smart grid applications. Most of the schemes proposed so far are based on non-linear methods, such as clipping and nulling. Even though these non-linear schemes reduce bit error rate (BER) by a significant amount, it will be shown in this paper that they can be easily outperformed by the proposed linear method. The performance improvement of the proposed algorithm comes from the fact that the identification of true locations of impulsive noise samples is very accurate, so that the reduction of the impulsive noise is only carried out at the truly contaminated samples of the received signal. This approach avoids typical problems encountered in clipping and nulling algorithms, where samples besides the ones containing the impulsive noise are also affected, thus creating additional distortion in the received signal. The superior performance of the proposed scheme is demonstrated via numerical simulations.","PeriodicalId":216807,"journal":{"name":"2016 International Symposium on Power Line Communications and its Applications (ISPLC)","volume":"145 11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129646168","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}

This has recently been extended to include power line communications (PLC). In this respect, we propose in this paper to enhance the EE of a dual-hop amplify-and-forward (AF) cooperative relaying PLC system by considering energy-harvesting (EH) at the relay node. The energy harvester exploits the high noisy PLC channel feature as well as the transmitted signal power to forward the source information. In light of this, we derive an analytical expression for the EE and verify it with Monte Carlo simulations. The performance of the conventional relaying system, i.e. without any EH, is also considered to clearly quantify the achievable gains. The results show that the proposed system can considerably improve the EE of PLC systems and that increasing the channel variance will always make the proposed system more energy-efficient.","PeriodicalId":216807,"journal":{"name":"2016 International Symposium on Power Line Communications and its Applications (ISPLC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126204212","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}

For this kind of signal there exist a number of methods based on the singular value decomposition (SVD) of a related Hankel matrix, that aim at either a de-noising or even a parameter estimation of the exponentials. We review these methods, extend one of them, and employ them for orthogonal frequency-division multiplexing (OFDM) based PLC channel estimation. Different from the more conventional channel estimation methods based on linear filters or time-domain sparsity, the methods we consider benefit from exploiting the parametric sparsity of the channel frequency response and are hence optimal in that sense. By means of simulation we compare their performance for PLC channels and discuss the suitability for different pilot models.","PeriodicalId":216807,"journal":{"name":"2016 International Symposium on Power Line Communications and its Applications (ISPLC)","volume":"174 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124291158","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}

A simple method to determine average noise power is described. Potential narrow band interferer, which may negatively affect the quality of the soft decision information, is detected and erased. Performance evaluation by using a simulated channel model and by using real field data shows that a proper consideration of frequency dependent noise power in the soft decision information can lead to a significant reduction of erroneous received packet compared to the case where a constant noise power over all subcarrier is assumed.","PeriodicalId":216807,"journal":{"name":"2016 International Symposium on Power Line Communications and its Applications (ISPLC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130212863","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 has been accomplished using 311 noise registers measured in the CENELEC-A band. Obtained results indicate that this model has a quite limited capability to represent the measured noise, since only 14.47% of the registers have amplitudes drawn from this distribution. Nevertheless, the analysis of these successful cases provides practical information for the utilization of the model. Hence, 56% of these cases can be adequately modeled by truncating the infinite sum in the class A probability density function (PDF) to two terms, which makes it equivalent to the Bernoulli-Gaussian model. It is also shown that the values of the impulsive index and the Gaussian to impulsive power noise ratio are inversely related.","PeriodicalId":216807,"journal":{"name":"2016 International Symposium on Power Line Communications and its Applications (ISPLC)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121850671","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 order to mitigate this interference, PLC systems need to stay silent on frequencies used for wireless communication. In PLC standard CENELEC EN 50561-1, these frequency exclusion requirements are partly adaptive and depend on whether the frequencies are actually used for communication. For reliable detection of the presence of wireless communication signals, we use MED-FCME LAD ACC algorithm. The performance of this algorithm is tested with actual power line measurement data in the 50-52 MHz frequency range. This frequency range is reserved for radio amateur communication and is an especially difficult case for signal detection due to varying power levels with SSB-modulated voice communication. The results indicate that the studied method performs well, providing means for more intelligent spectrum utilization and reduction of interference levels in a broadband cognitive PLC-network.","PeriodicalId":216807,"journal":{"name":"2016 International Symposium on Power Line Communications and its Applications (ISPLC)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129061577","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 colour wheel method is exploited to map PSK symbols to colours. We define a parameter x, which represents different magnitudes of the PSK complex symbol observed over the PLC channel. x is adjusted to an optimal value to meet the requirement of the CSK design. The bit error rate (BER) is analysed and the performance of the system is presented for multiple values of the modulus of the detected PSK symbol. A practical implementation is performed to verify the PSK-CSK mapping method.

In the case of a wide scale smart-meter roll-out, a tool allowing a Distribution System Operator (DSO) to estimate the performance of a G3-PLC communication without the need to install test modems would be efficient. In this perspective, this paper presents a compliant ITU-T G.9903 G3-PLC PHY [1] software simulator for both the CENELEC-A and FCC bands. The ultimate goal of this simulator is to evaluate the impact of different impairments on a G3-PLC communication.
