To reduce the number of pilots, several algorithms including blind, semi-blind, and decision-directed (DD) approaches are proposed. Most of these algorithms assume the channel varies block-wisely, but remain invariant within one OFDM block duration. However, such channel model neglects the inter-(sub)channel interference (ICI) and may be not practical for fast time-varying channels. In this paper, we propose an ICI self-cancellation algorithm under an architecture that could be readily incorporated into an OFDM system that does not take the ICI into consideration. Our algorithm involves only periodic extension and linear combination, and incurs almost no additional complexity. The ICI can be completely removed if the variation of each path in the channel is linear with time during one extended OFDM block. Our algorithm also provides a trade-off between performance and throughput. To validates the proposed algorithm, we incorporate it into an OFDM system with pseudo-pilot (PP) detection. The simulation validates the efficiency of the proposed algorithm, and that neglecting the ICI in fast time-varying channels is impractical.","PeriodicalId":230233,"journal":{"name":"2009 IEEE Sarnoff Symposium","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116068046","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}

Topological information about the underlying network is beneficial for improving the performance, devising reliability schemes, ensuring low overhead, and enhancing the scalability of such systems. Topology information is often obtained with the support of the network infrastructure. Unfortunately, this support is often limited and sometimes not reliable. Various techniques have been proposed to infer useful information about the structure of the IP topology using strictly end-to-end measurements. In this paper, we rely on path sharing information between the nodes of a distributed system collected using end-to-end measurements and explore how much of the logical topology can be inferred using only this information. We propose an algorithm to construct such an inferred graph and evaluate this algorithm by simulations. In the synthetic topologies we considered, error in the estimated distances between the end nodes is on average a negligible fraction of the diameter for the tree topologies and less than 20% of the diameter for denser graphs.","PeriodicalId":230233,"journal":{"name":"2009 IEEE Sarnoff Symposium","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133159681","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}
