The VI-CFAR is a composite CFAR processor that dynamically selects between different conventional adaptive thresholding algorithms, depending on the background environment, in order to maintain constant false alarm rate (CFAR). It utilizes the concept of data variability, and computes a second-order statistic called the variability index (VI) to dynamically tailor the background estimation algorithm. Previously this type of CFAR has only been studied for the case of Gaussian background clutter. However, studies show that the Weibull distribution provides a better fit for many clutter situations. The VI-CFAR parameters for the case of Weibull clutter have been designed and performance curves for the homogeneous background case have been plotted. Results show that the VI-CFAR processor has satisfactory performance with low CFAR loss","PeriodicalId":171255,"journal":{"name":"2006 IEEE International Multitopic Conference","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114722842","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}

Most of the proposed architectures and solutions for mobility management use complex processing to reduce handoff latencies. In this paper a light-weight fast mobility management scheme is proposed which is based on strategic deployment of wireless LAN (WLAN) hotspots in a hierarchy of overlapped components like handoff anchor points (HAP), access routers (ARs) and access points (APs). The major handoff decision is taken in the HAP, a novel component in proposed architecture, which last for a significantly longer time due to reduced chances in probable moving path and by sending early binding updates through active ARs. Handoff latency has been reduced to almost link layer handoff time with a high level of predictability and reliability. Simulation results highlight improvements achieved in throughput, scalability, and handoff latencies.","PeriodicalId":171255,"journal":{"name":"2006 IEEE International Multitopic Conference","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125466662","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}

Predictability refers to the degree that a correct forecasting of a time series can be made. Prediction can be erroneous. So it is important to know the predictability of the time series before going for prediction. In this paper six new predictability metrics have been presented. The proposed predictability metrics are evaluated by using single-step-ahead and multistep-ahead forecasting by nearest neighbor method. The variation of predictability metrics with signal to noise ratio is determined. The proposed metrics found stable. The predictability metrics for three benchmark time series is calculated and compared with already proposed metrics in literatures. It is found that proposed metrics are more useful for analyzing the time series.","PeriodicalId":171255,"journal":{"name":"2006 IEEE International Multitopic Conference","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126578584","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}

These PSO-MIMO and MPSO-MIMO system detectors significantly reduce the computational complexity as compared to the conventional maximum likelihood (ML) detection technique. The simulation results achieved with these detectors show near ML performance.
