So, in PLC there are multiple models of channel, physical, datalink and other layers, which are realized separately in multiple programming environments. Nevertheless it is often advantages to do a cross-layer optimization of communication protocols. For this purpose multiple separate models have to be unified in one simulation environment. This paper describes a modeling approach of the PLC channel, the topology generator, the physical and datalink layer in ns-3 together. With this approach the authors show that Linear-Periodic Time-Variant (LPTV) property of the PLC channel is useful to be considered for the design of MAC scheduler. The developed simulator is set up for in-home PLC environment. It means that noise, impedance models and topology generator are described as stochastic models, which base on statistical measurement results in this environment.","PeriodicalId":222123,"journal":{"name":"2015 IEEE International Symposium on Power Line Communications and Its Applications (ISPLC)","volume":"82 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":"129901981","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 this paper, resistive coupling as a radical and novel approach is investigated specifically for the reception of PLC data. The main goal of this new approach, is to reduce costs associated with traditional capacitive and inductive couplers, seeing that resistors are the cheapest electronic components available. Only two resistors are required to implement a voltage-divider setup which reduces the harmful ac power waveform to a safe level, after which (cheaper) low-spec components can be used to filter and process the scaled-down, sampled waveform. Simulation results as well as off-line and live experimental results are shown to confirm that the superimposed PLC signal can be extracted successfully with resistive PLC coupling.","PeriodicalId":222123,"journal":{"name":"2015 IEEE International Symposium on Power Line Communications and Its Applications (ISPLC)","volume":"15 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":"128152162","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}

One way to achieve higher data rates in PLC networks is to operate at higher frequencies and increase the used bandwidth. In the future, the increased PLC frequency range can overlap with several wireless communications systems resulting in interference for these transmissions and vice versa. Commonly used static notching results in inefficient spectrum utilization as in a given place and at a given time only a part of the frequency range may be occupied by other wireless systems. Some wireless signals like FM signals are very closely spaced. In practice it is impossible to utilize these narrowband unoccupied frequency bands. In this case we can cluster closely spaced signals. Guard bands around detected wireless signals must also be taken into account before defining usable frequency bands for PLC. In this paper, we use the 2-D LAD ACC algorithm to detect and cluster interfering signals. We also further develop the algorithm so that after clustering guard bands are added and reclustering, if necessary, is executed. The performance of this modified 2-D LAD ACC algorithm is analyzed using calculations and spectrum analyzer measurement results obtained from in-office PLC network in the frequency range 80-200 MHz. The results verify that the proposed method performs well by detecting and clustering continuous and non-continuous wireless signals and providing means for clever spectrum utilization in PLC-network.","PeriodicalId":222123,"journal":{"name":"2015 IEEE International Symposium on Power Line Communications and Its Applications (ISPLC)","volume":"1 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":"130698751","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 this paper, we study the applicability of IA for MIMO power line communication (PLC) in interference scenarios. In particular, we consider different MIMO PLC networks to study the feasibility of IA as well as evaluate the performance in terms of sum-rate for these setups. To this end, we exploit minimum interference leakage (Min-IL) and maximum signal to interference plus noise ratio (Max-SINR) algorithms that were earlier proposed for IA in the context of MIMO wireless interference networks. Our results show that IA can be equally applicable to the MIMO PLC in interference scenarios as well as the sum-rate of the PLC networks can be significantly improved through the exploitation of Max-SINR algorithm. It is found that at high signal to noise ratio (SNR) the performance gain in terms of sum-rate with IA over orthogonal transmission techniques is around 30% for a 3-user 2 × 2 MIMO PLC network.","PeriodicalId":222123,"journal":{"name":"2015 IEEE International Symposium on Power Line Communications and Its Applications (ISPLC)","volume":"8 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":"121884716","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}

An energy-pattern based sequence detection algorithm is proposed for the recognition of a wake-up sequence by the receiver. The method is characterized by low computational complexity and does not require channel parameter estimation and adaption. Furthermore, a blind packet repetition technique is introduced that accomplishes periodic impulsive noise avoidance. A realistic and straightforward narrowband power line channel model is presented and the proposed wake-up protocol is verified against it in terms of Monte-Carlo simulations. It is demonstrated, that the method leads to significant improvements compared to state of the art low-complexity PLC systems in typical NB-PLC channels.","PeriodicalId":222123,"journal":{"name":"2015 IEEE International Symposium on Power Line Communications and Its Applications (ISPLC)","volume":"89 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":"115661475","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 GI length is chosen so that there is no interference, i.e. the GI length is greater than or equal to the channel impulse response length. However, many previous works have shown that in PLC systems, this GI choice is inefficient in terms of achievable throughput. Indeed, shorter GI evidently results in inter-symbol interference (ISI) and inter-carrier interference (ICI), but the gain offered by shortened GI may exceed the loss caused by interference. In this paper, we propose a simple solution for the GI length adaptation in PLC systems to optimize the achievable throughput.","PeriodicalId":222123,"journal":{"name":"2015 IEEE International Symposium on Power Line Communications and Its Applications (ISPLC)","volume":"5 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":"117313479","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}

Due to the different behavior of the power line channel mainly OFDM based PHY-Layers, significant modulations and decoding times are used. The resulting computation delay is equivalent to 3-5 OFDM symbol times, which has an equivalent effect on the system as a propagation delay. The short ACKs for confirmation are full packages with several OFDM-symbols. The impulsive noise on the channel requires certain packet duration to reach sufficient reliability. Therefore a stop and wait protocol with immediate acknowledgement of each packet cannot reach an efficient channel usage. Additionally it is necessary for reliable PLC systems to accept links with PER (packet error rates) of 20% and more. The theoretical maximum throughput of a channel with PER of 20 % is still 80%. Very often narrowband PLC standardized protocols fail under this condition. This paper presents an adopted Layer-Design to combine all data flows to a node in a single stream and organize a reliable data transmission even for channel with PER of 90% and more. A pipeline structure allows an efficient medium usage and realizes a selective repeat approach. The confirmation is transferred piggy back in packages in opposite direction. Even for the retransmission of a packet the transmission mode and the route can be changed. This approach allows fast reactions on changed network situations without interruption of any link, which is an important requirement to fulfill reliability and real-time requirements for grid control.","PeriodicalId":222123,"journal":{"name":"2015 IEEE International Symposium on Power Line Communications and Its Applications (ISPLC)","volume":"31 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":"129095482","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}
