First we set a simple two-port model of a network and calculate complex attenuation factor from the z- parameters, which are expressed in terms of impedances easily calculable/measurable from the network's ports. We provide all the elements for a simple end efficient propagation model, including propagation by crosstalk between different circuits in e.g. three phase networks, as well as influence of the loads connected to the ports of different circuits on such networks. We conclude that the model shown is suitable for PLC channels simulations, giving very accurate results and enabling modeling of wide band channel characteristics. Since the propagation model relies on impedance calculations, we can also use it for the calculations of impedances seen from network termination ports. With the developed tool we have been able to predict channel propagation factors in both real and imaginary part, as well as port impedances, in very complex networks, which could not be achieved with usual time domain approach in an economic way 1 .","PeriodicalId":169376,"journal":{"name":"IEEE International Symposium on Consumer Electronics, 2004","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130494507","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}
