Combining a modified Prony signal approximation and Gram-Schmidt orthogonalization schemes (to obtain the orthogonal bases), the proposed method represents the processed signal as the sum of M damped exponentials. It is shown that the employed bases are closely related to the roots of an Mth order forward linear prediction polynomial, satisfying the system. In addition, an optimization procedure is described to optimally adjust these bases to accurately represent the signal under consideration. The proposed procedure finds applications in signal compression and signal de-noising, where it is only necessary to specify the orthogonal basis, as well as the decomposition weights rather than sending the complete signal batch. Illustrative examples are given","PeriodicalId":421826,"journal":{"name":"Proceedings of the Fifth IEEE International Symposium on Signal Processing and Information Technology, 2005.","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127862806","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}

In the proposed scheme, the Alamouti's space-time block coding (STBC) method is extended to multiuser systems. Moreover, to mitigate multiple access interference in the conventional receivers, the linear transmit preceding technique is used in the transmitter. We show that using STBC codes in conjunction with transmit preceding in CDMA systems can significantly increase the capacity of these systems. In this method, the mobile terminals are simple and they do not need any information about other users' spreading sequences. Our computer simulations show that the proposed method has the same performance as the methods based on the combination of receive diversity and multiuser detection in the uplink of CDMA systems","PeriodicalId":421826,"journal":{"name":"Proceedings of the Fifth IEEE International Symposium on Signal Processing and Information Technology, 2005.","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114585485","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}

As in some applications noise characteristics are unknown, in this research, a criterion which its minimization leads to the best parameter set up is introduced. The proposed criterion is evaluated for the wavelet shrinkage image denoising algorithm using the cross validation procedure. The criterion is tested for some different values of thresholds, and the output leading to the minimum criterion value is selected as the final denoised output. The resulting outputs of our method and the previous threshold selection scheme for the wavelet shrinkage, i.e. the median absolute difference (MAD), are compared.

Face localization aims to determine the image position of a face for verification purpose of documents such as passport, driving license, ID cards, etc. In this paper an entropy-based method is proposed for detecting the high information region of the image, which may include eyes, mouth, nose, etc. The derived regions in this stage of recognition are sent to feature extraction and classification phase. The method has been tested on the ORL database. The results show the effectiveness and robustness of the proposed method for face detection and localization in presence of white additive Gaussian noise up to 25 dBw.

This paper considers such challenges, linked to the consumer's understanding and the usability of the security features placed before them. The need to ensure threat awareness is well illustrated by the problem of phishing - a threat that can specifically target eCommerce users, and which explicitly uses their lack of knowledge as a basis for exploitation. Having established a need for protection, the discussion proceeds to consider the barriers posed by security technologies themselves, identifying a range of issues that may specifically be encountered by end-users.

These arrangements are provided through security techniques, mainly encryption, and the distribution, in a detached manner, of content and rights. This allows free access to the content by the consumers, but only those carrying the proper right object (RO) will be able to process such content. As a security service considered in different layers of the security framework defined by ITU X.805, almost all applications need to consider non-repudiation in the very beginning of their design. Unfortunately this has not been done so far in DRM specifications due to practical issues and the type of content distributed.
