A 2-input / 3-output spatial channel model response is simulated for a 3-phase MV broadcast network over the 3-500 kHz frequency band. We optimize the precoder design according to the signal-to-leakage-plus-noise ratio criterion and show how the design is different from the wireless scenario. The achievable MIMO-OFDM data rates are evaluated for a group-based multicasting scenario under two different grouping criteria. First, we consider a distance-based criterion where the users within the same geographical area receive a common message. Second, we consider a quality-of-service based criterion where the premium users have a lower bit error rate than the standard users. We demonstrate a significant sum-rate gain for the multicast networks over the broadcast networks for a wide range of noise levels.","PeriodicalId":222123,"journal":{"name":"2015 IEEE International Symposium on Power Line Communications and Its Applications (ISPLC)","volume":"334 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124303647","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}

Current battery management systems use standard CAN busses for the communication between the battery control unit (BCU) and battery modules, which comprise lithium-ion cells. In contrast, in next-generation batteries the BCU should communicate with each lithium-ion cell in a battery pack to make them safer and increase their performance. However, this can lead to data rates up to 2 MBit/s, which cannot be handled by a standard CAN bus. Furthermore, connecting battery modules by CAN bus wires increase costs and bulk. We are investigating new data bus concepts in order to make lithium-ion batteries safer, with less cost, and less bulk. The Power Line Communication is one way to reach this goal. Using a battery pack as a power-line network, however, requires a different coupler system than in mains electricity. This is because of high direct currents up to 1000 A, which could easily lead to saturation in an iron-cored coupler. Rogowski coils are air-cored coils with no saturation effects, no matter how high the current. In this paper, we show some experimental measurements, such as measurements of the impedance and the transfer function of Rogowski coils. The results show that Rogowski coils are a viable approach as coupler for PLC in lithium-ion battery packs.","PeriodicalId":222123,"journal":{"name":"2015 IEEE International Symposium on Power Line Communications and Its Applications (ISPLC)","volume":"335 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124711004","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 efficiency of this method, however, is found to be not only impacted by the threshold selection but also by the average peak-to-average ratio (PAPR) value of the orthogonal frequency division multiplexing (OFDM) signals. As such, the blanking capability can be further enhanced by reducing the PAPR value. With this in mind, in this paper we evaluate the performance of constant envelope OFDM (CE-OFDM) which has inherently the lowest achievable PAPR of 0 dB; therefore, the proposed system is expected to provide the lower bound performance of the blanking-based method. In order to characterize system performance, we consider the probability of blanking error and signal-to-noise ratio (SNR) at the output of the blanking device. The results reveal that the proposed system can achieve significant improvements over the conventional OFDM blanking-based scheme in terms of minimized probability of blanking error. It will also be shown that output SNR gains of up to 6 dB can be attained over the conventional OFDM blanking-based systems.","PeriodicalId":222123,"journal":{"name":"2015 IEEE International Symposium on Power Line Communications and Its Applications (ISPLC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128418305","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 non-Gaussian nature of this interference provides an opportunity for its effective mitigation by nonlinear filtering. In this paper, we introduce blind adaptive analog nonlinear filters, referred to as Adaptive Nonlinear Differential Limiters (ANDLs), that are characterized by several methodological distinctions from the existing digital solutions. When ANDLs are incorporated into a communications receiver, these methodological differences can translate into significant practical advantages, improving the receiver performance in the presence of non-Gaussian interference. A Nonlinear Differential Limiter (NDL) is obtained from a linear analog filter by introducing an appropriately chosen feedback-based nonlinearity into the response of the filter, and the degree of nonlinearity is controlled by a single parameter. ANDLs are similarly controlled by a single parameter, and are suitable for improving quality of non-stationary signals under time-varying noise conditions. ANDLs are designed to be fully compatible with existing linear devices and systems (i.e., ANDLs' behavior is linear in the absence of impulsive interference), and to be used as an enhancement, or as a simple low-cost alternative, to the state-of-art interference mitigation methods. We provide an introduction to the NDLs and illustrate their potential use for noise mitigation in PLC systems.","PeriodicalId":222123,"journal":{"name":"2015 IEEE International Symposium on Power Line Communications and Its Applications (ISPLC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122460223","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}
