Although many authors studied the performance of the OFDM systems under the impulsive noise, their considerations are mostly restricted to OFDM systems with a large number of subcarriers. In that case, discrete Fourier transform (DFT) spreads the impulsive noise in such a way that its distribution in the frequency domain can be approximated as Gaussian. If the number of subcarriers is small, these methods can be hardly used. We describe an iterative algorithm for correcting the impulsive noise erors for the OFDM transmission with a small number of subcarriers. Simulation results for a 16-OFDM-QPSK systems show that the influence of impulive noise can be essentially reduced.","PeriodicalId":321296,"journal":{"name":"2009 IEEE International Symposium on Power Line Communications and Its Applications","volume":"02 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128556096","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 particular, the proposed channel estimation exploits the sounding procedure available in HomePlug AV, by averaging the estimates of the channel collected during several received frames. To allow the channel estimation to properly work also in the case of a non ideal frame synchronization, a method to estimate the frame synchronization offset between successive frames is presented. Numerical results, in terms of BER versus signal-to-noise ratio, show that the performance of the proposed channel estimation almost overlaps the performance achieved with perfect channel knowledge.","PeriodicalId":321296,"journal":{"name":"2009 IEEE International Symposium on Power Line Communications and Its Applications","volume":"24 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133105689","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 a PLC cell, the users are not moving but their statuses and traffic demands are changing during the run-time. These cells may interference with each other; therefore, each cell has a fixed amount of transmission capacity for its transmissions. The transmission capacity is defined as a set of channels. Since the active users and traffic demands in each cell are variable, the users in different cells may get different amount of resource for their transmission. This situation leads to the problem of unfairness between users. Furthermore, when the cells are not interfering, they can use the same channels for their parallel transmissions. The overall multi-cell structure may also change dynamically due to the activation and deactivation of some cells, which requires a method for re-arranging the allocated channels between the working cells. Therefore, a method which allows the dynamic sharing of the transmission capacity between the cells is required. In this paper, we propose a negotiation strategy to allow the cells to cooperate and dynamically share the channels in a distributed fashion. The negotiation strategy is based on two procedures, seizing the channels if they are free and releasing channels if a cell has more channels per user than its neighbors. The proposal is analyzed and several aspects are discussed in this paper.","PeriodicalId":321296,"journal":{"name":"2009 IEEE International Symposium on Power Line Communications and Its Applications","volume":"126 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116371461","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}

Among them, impulsive noises are the main source of interference resulting in signal distortions and bit errors during data transmission. Many impulsive noise models were proposed in the literature. They share the same impulsive noise definition: “unpredictable noises measured at the receiver side”. This definition leads to the modelling of thousands of impulsive noises whose plurality would very likely come from the diversity of paths that the original impulsive noise took. In this paper, an innovative modelling approach is applied to impulsive noises which are henceforth studied directly at their sources. Noise at the receiver is considered as the noise model at the source filtered by the powerline channel. Effective in-device sources of impulsive noises are identified and classified into six classes, from which representative noises are proposed. Based on impulsive modelling at source, a receiver side model is finally proposed.","PeriodicalId":321296,"journal":{"name":"2009 IEEE International Symposium on Power Line Communications and Its Applications","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128591372","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 general, the FDM is better solution for the systems which require real-time performance, but interference signals from adjacent sub-networks must be rejected by the analog filters to prevent the receiving sensitivity degradation of the desired signals. In this paper, a novel filter circuit, called “Multi-Band Filters”, is proposed to realize analog band-pass filter banks. The design method and the measurement results of the frequency characteristics of the Multi-band Filters are shown in this paper.

Control and diagnostic information are transmitted back from the motor to the inverter through an extra cable dedicated for data transmission. This signal information can be sent through the feeder cable that powers the motor using the Power Line communication technology ‘PLC’. The existing PLC modems developed for domestic applications may not be suitable for data transmission over feeder cables. We will propose a PLC modem with convenient characteristics that fit for the industry. It will help us to send control information such as rotor position and temperature back to the inverter through the feeder cable already polluted by the PWM signal. Therefore, some of the modem aspects will be revealed in this paper. Studies carried out on modulation's techniques and throughput in question will help us to define the frequencies to use. We will highlight the difficulties and limitations that obstruct transmission between the motor and the inverter. We will underline the real cause of non-functioning and the possible way to overcome it. Finally, we will define the coupling interface and the modem characteristics and the frequency's band that might be convenient. Simulations and experimental results will confirm the proposed analyses and will put in evidence the achievable performance of the proposed PLC modem.","PeriodicalId":321296,"journal":{"name":"2009 IEEE International Symposium on Power Line Communications and Its Applications","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134629446","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}
