Turbo equalization algorithms always need perfect knowledge of the channel response. In this paper, we propose a blind turbo equalization and iterative channel estimator scheme. A fractional super-exponential blind equalizer is used to provide timing recovery and the a priori information that the SISO equalizer and soft-decision directed channel estimator need in the first turbo iteration. In order to reduce complexity, a simplified computation of the equalizer’s extrinsic information for MPSK modulation is used. Simulation results show that the proposed algorithm works effectively for multi-level modulations over severe frequency selective channel.","PeriodicalId":108594,"journal":{"name":"2010 International Conference on Communications and Intelligence Information Security","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117191535","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}

It has wide application, but it is exposed to kinds of security threats. Key management is vital important in ad hoc network security research field. Firstly the related work about key management in mobile ad hoc network is analyzed, and then an algorithm is proposed based on identity-based generalized signcryption. Lastly a suitable key management scheme is put forward based on generalized signcryption and threshold cryptograph. This scheme not only saves the user’s storage, but also decreases the communication and computation overhead because of generalized signcryption. The detailed key generation and key update schemes ensure the scheme’s availability.","PeriodicalId":108594,"journal":{"name":"2010 International Conference on Communications and Intelligence Information Security","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123018586","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}

Many different kinds of AUVs have been designed in recent years around the world. Sensors should be installed to navigate autonomously and map characters of the ocean for AUV. In this paper, we address the problem of orientation in the process of positioning the motion ship and AUV during retrieve. Affecting by many factors from outside, sensors data are preprocessed and adopted with cubic spline interpolation method for time registration. Performance of the sensors is measured and used as the weight to achieve data fusion, and maximum likelihood estimate fusion method is established to figure out the problem of multi-sensor data fusion. The validity of this multi-sensor data fusion model and the practicability of the fusion data are tested based on experiment results.","PeriodicalId":108594,"journal":{"name":"2010 International Conference on Communications and Intelligence Information Security","volume":"356 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123109465","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}
