The transformer is an integral component of the electrical transmission lines. But high frequency signals cannot pass through the transformer and hence it is essential for them to traverse an alternate path, effectively bypassing the transformer. This paper describes a transformer bypass circuit. The mechanism described allows signals to be retained in the analog domain while bypassing the transformer.","PeriodicalId":153251,"journal":{"name":"International Symposium on Power Line Communications and Its Applications, 2005.","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130393137","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}

Two kinds of channel measurements were performed: impulse response measurements and noise signal measurements. In measure based channel model, the performance degradation is analyzed due to timing synchronization and colored noise in orthogonal frequency division multiplexing (OFDM) based power line communication (PLC) systems and then proceeds to propose a new receiver scheme for channel estimation and soft decision decoding scheme under imperfect channel estimation. Simulation results show that the proposed algorithm can efficiently eliminate the effects of imperfect channel estimation and colored noise for coded OFDM system.","PeriodicalId":153251,"journal":{"name":"International Symposium on Power Line Communications and Its Applications, 2005.","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130585166","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}

Since the power-line is a complex medium not suited for data transmission, hence classical routing is not efficient For this purpose, and thanks to the physical layer emulator [Bumiller, G, 2004] implemented by iAd, we used the simulation approach to derive important design parameters such as repeater level variation, packet error rate, etc. The understanding of the influence of these parameters allowed us to develop an efficient protocol. This work has been carried out as part of the REMPLI project (European program NNE5-2001-00825, www.Rempli.org). The main objective of REMPLI is to develop a distributed infrastructure suitable for real-time monitoring and control of energy distribution and consumption. PLC technology has been chosen to form the main communication infrastructure.","PeriodicalId":153251,"journal":{"name":"International Symposium on Power Line Communications and Its Applications, 2005.","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132218190","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}

Traditionally, performance characteristics for orthogonal M-FSK in the presence of AWGN assume that the individual symbol carriers are exposed to the same channel signal-to-noise ratio (SNR). This is true in the case where only the flat part of the magnitude response of the coupling circuit is considered adequate for symbol carrier positioning. However, with bit loading techniques and error correction even the non-flat parts with steep roll-off can be used to position additional symbol carriers, thus creating possibilities for increased robustness against frequency-related disturbances as a result of using more symbol carriers. When this option is used, the individual symbol carriers are not always exposed to the same channel SNR. This study assumes only the presence of AWGN, due to its emphasis on the impact of the transmitter coupling circuitry's varying filter characteristic.","PeriodicalId":153251,"journal":{"name":"International Symposium on Power Line Communications and Its Applications, 2005.","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123822560","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}

Therefore, in this paper, we consider such channel coders for a power line communications scenario, where such conditions create a hostile channel environment. The proposed channel coder assumes the knowledge of the noise covariance matrix. The transmission is accomplished over the N weakest eigenmodes of the noise, which are identified by means of a broadband eigenvalue decomposition. We demonstrate by simulations that this approach can lead to an enhancement of the SNR in the receiver and to improved performance over standard channel coding approaches.","PeriodicalId":153251,"journal":{"name":"International Symposium on Power Line Communications and Its Applications, 2005.","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127913856","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 signals are assumed to be transmitted over AWGN channels.
