Such improvements may be necessary to enhance coverage in buildings and for portable hand-held units, to extend cell-site range and coverage at reduced infrastructure cost, and to increase the capacity of existing cell sites. Often, these benefits can be made available at a fraction of the cost of new cell sites. Improvements in range and coverage can be achieved with intelligent multibeam antenna systems that provide greater antenna gain and discrimination against interference. Range extension is achieved by increasing available signal-to-noise ratio. Range improvements for intelligent antenna systems, when compared to the performance of conventional sector antennas, have been demonstrated to exceed 40%. Increased capacity can be achieved when the signal-to-interference level is improved through digital signal processing techniques that place the desired signals in or near the narrower main beam of the multibeam antenna and place interferers into the pattern sidelobes and/or nulls. Computer simulation, using terrain-based propagation models and a real cellular system lay-down, predicts greater than 6-dB improvement in signal-to-interference for multibeam antennas when compared to sector antennas. This improvement has been corroborated by measurement, and can nearly double capacity while maintaining the same quality of service.","PeriodicalId":199600,"journal":{"name":"Southcon/96 Conference Record","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114584622","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 central tenet of this method and model suggests a strong connection between additive number theory (partitions) and statistics-in that, it shows how a scatterplot or a set of data, if modeled as a finite binary string, can be 'classified' using partition theory. Secondly, this method contributes the idea of using partitions as a model from which objective probabilities are derived-thus, linking the concept of statistics with data compression via partition theory. In the context of this method and model, a third important idea emerges-in which, a set of data or a scatterplot is converted into a unique real number (called a CADAMA number) which can be plotted and used for the purpose of storing and retrieving the original set of data, data analysis, and can potentially enhance or guide the decision-making process of a decision-maker. Finally, this method and model provides an opportunity to further validate, reexamine, and refine some of the fundamental first principles in statistics from a number theoretic point of view.","PeriodicalId":199600,"journal":{"name":"Southcon/96 Conference Record","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124052966","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}

We argue that a watermark must be placed in perceptually significant components of a signal if it is to be robust to common signal distortions and malicious attack. However, it is well known that modification of these components can lead to a perceptual degradation of the signal. To avoid this, we propose to insert a watermark into the spectral components of the data using techniques analogous to spread spectrum communications, hiding a narrow band signal in a wideband channel that is the data. The watermark is difficult for an attacker to remove, even when several individuals conspire together with independently water-marked copies of the data. It is also robust to common signal and geometric distortions such as digital-to-analog and analog-to-digital conversion, resampling, and requantization, including dithering and recompression and rotation, translation, cropping and scaling. The same digital watermarking algorithm can be applied to all three media under consideration with only minor modifications, making it especially appropriate for multimedia products. Retrieval of the watermark unambiguously identifies the owner, and the watermark can be constructed to make counterfeiting almost impossible. Experimental results are presented to support these claims.","PeriodicalId":199600,"journal":{"name":"Southcon/96 Conference Record","volume":"234 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132361860","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}
