The fundamental idea of our study is to introduce a reference residual model generator to formulate the robust fault detection filter as a robust H∞ model matching problem through which the generated residual can be evaluated. By applying the robust H∞ optimization control technique, the reference residual model can take into account the robustness against disturbances and sensitivity to faults simultaneously. The robust H∞ optimization control technique is presented via a linear matrix inequality (LMI) formulation. A drum boiler model is used to demonstrate the design procedures and the applicability of the proposed approach.","PeriodicalId":119104,"journal":{"name":"2011 IEEE GCC Conference and Exhibition (GCC)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123821966","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}

Properties of multipath taps along with angular and power values of clusters are included in this model to consider wideband signal with frequency selective fading channels. Link performance of systems that utilize UCA at both link ends, the access point (AP) and mobile associated stations (STAs) are investigated. Standard IEEE802.11 TGn channel scenarios are used to simulate different realistic environments. Characteristics of ergodic channel capacity versus azimuth orientation of UCA arrays are analyzed and compared with that of uniform linear array (ULA). Also, the water filling (WF) power allocation scheme performance is investigated under different conditions. Performance of VBLAST UCA bases receivers in combination with successive interference cancelation are also presented for different TGn channel models by utilizing the proposed channel model.","PeriodicalId":119104,"journal":{"name":"2011 IEEE GCC Conference and Exhibition (GCC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129989559","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}

Tracking is done independently for each view. Fusing several cues including color, edge, texture and motion constrained by structure of environment is used in a novel way and in particle filter framework. The results of individual image planes are projected to ground plane using homography relation. The similarity of projected locations with the reference model and minimum variance estimate are two key points to evaluate the location of the target. Also, we introduce a method based on two views tracking to handle occlusion. Robust statistic is used to declare an occlusion in one view. Homography relation and inter-frame transformation are the tools to cancel the occlusion. Experimental results show the robustness and accuracy of the proposed method.","PeriodicalId":119104,"journal":{"name":"2011 IEEE GCC Conference and Exhibition (GCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128955408","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 availability of multiple relay paths in IEEE 802.16j motivates two relay configurations: relay diversity and relay multiplexing. Existing works have focused on the relay diversity method. In this paper, we explore the relay multiplexing alternative. Using the concept of code-division multiple relay access (CDMRA), where relay stations (RS) are assigned unique access codes for parallel relaying of independent data streams from source to destination, we derive the capacity of the relay multiplexing system in comparison with the relay diversity methods. We show that while the capacity of the diversity methods grows with the log of the system SNR, the capacity of the relay multiplexing approach grows linearly with the number of parallel relay paths created in the system for iid channel case. Relay multiplexing thus provides affordable means of realizing high-speed multihop communications.","PeriodicalId":119104,"journal":{"name":"2011 IEEE GCC Conference and Exhibition (GCC)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130081840","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}
