Now-a-days various DSP systems are implemented on a variety of programmable signal processors or on application specific VLSI chips. Coordinate Rotation Digital Computer (CORDIC) algorithm has turned out to be widely researched topic in the field of vector rotated Digital Signal Processing (DSP) applications due to its simplicity. This paper presents the design of pipelined architecture for coordinate rotation algorithm for the computation of loop performance of complex Digital Phase Locked Loop (DPLL). The design of CORDIC in the vector rotation mode results in high system throughput due to its pipelined architecture where latency is reduced in each of the pipelined stage. Saving area on silicon substrate is essential to the design of any pipelined CORDIC. The area reduction in proposed design can be achieved through optimization in the number of micro rotations. For better loop performance of first order complex DPLL and to minimize quantization error, the number of iterations are also optimized.","PeriodicalId":175615,"journal":{"name":"2010 3rd International Conference on Emerging Trends in Engineering and Technology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122704649","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 current generation of vehicles has embedded computers, GPS receivers, and number of sensors, where as the next generation of these vehicles will potentially have short-range wireless network interface. The target of ITS (Intelligent transport system) is to increase safety of passenger by exchanging warning messages between vehicles, this can be done by offering on-board network applications which is a challenge for the scientific community. In addition to safety applications, other telemetric services could improve traffic efficiency environment preservation, comfort and provide a reliable journey. Since VANET (Vehicular Adhoc Network) is composed of vehicles equipped with short range wireless communication capabilities. The performance of vehicles can be affected by high mobility pattern of the vehicle, speed of vehicle, transmission range, network breakup, traffic density and number of vehicles in the route. This paper describes the effect of the wireless transmission range on the lifetime improvement of the routing path in VANET, simulation result obtained helps to select the appropriate transmission range for increasing the lifetime of the routing path.","PeriodicalId":175615,"journal":{"name":"2010 3rd International Conference on Emerging Trends in Engineering and Technology","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130858481","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}

Perceptual transparency refers quality of image which is measured by ‘Peak Signal to Noise Ratio’ (PSNR). Robustness is measured in terms of ‘Correlation Factor’ (ρ). A good quality watermarking scheme should have maximum PSNR, ideally Correlation Factor equals to 1 and should have maximum watermark information hiding capacity. In this paper, we have presented strongly robust digital image watermarking scheme based on ‘Discrete Wavelet Transform’, by embedding scrambled watermark in middle frequency sub band. The security levels are increased by generating PN sequence depending on periodicity of watermark image. The image scrambling is applied by Arnold Transform. The decomposition is done with ‘Haar’ which is simple, symmetric and orthogonal wavelet and the direct weighting factor is used in watermark embedding and extraction process. The scheme results in exact recovery of watermark with standard database images of size 512x512, giving Correlation Factor equals to 1. The Correlation Factor for different attacks like Noise addition, Filtering, Rotation and Compression ranges from 0.90 to 0.95. The PSNR with weighting factor 0.02 is up to 48.53 dBs. The presented scheme is nonblind and embeds binary watermark of 64x64 size.","PeriodicalId":175615,"journal":{"name":"2010 3rd International Conference on Emerging Trends in Engineering and Technology","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132966828","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}
