To make the transceiver performance more efficient we need to follow IEEE 802.15.4 standard to address the needs of low data rate, low power consumption and low cost sensor networks with improved performance. In this paper PHY layer of Zigbee transceiver using orthogonal quadrature phase shift keying (OQPSK) modulation scheme with half sine pulse shaping and direct sequence spread spectrum (DSSS) technique is designed, and its performance under rayleigh fading channel is analyzed. Matlab Simulink is used to develop the system level design and its performance is analysed with bit error rate (BER) of the transceiver by increasing signal to noise ratio (SNR).","PeriodicalId":174192,"journal":{"name":"2015 International Conference on Communications and Signal Processing (ICCSP)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132778932","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 key idea behind the proposed approach deals with information hiding in image using Zig-Zag scanning pattern which is more complex algorithm in Steganography again encrypted as shares by VC technique for embedding in separate host images to provide authentication for the VC shares which makes these secret shares invisible by embedding them into host images. The secret shares generated from VC encryption are watermarked into some host images using digital watermarking. Digital watermarking is used for providing the double security of image shares. The share is embedded into the host image using Least Significant Bit Insertion Technique (LSB). The scheme provides more secure and meaningful secret shares that are robust against a number of attacks. The performance of the proposed system is evaluated using peak signal to noise ratio (PSNR), histogram analysis and also numerical experimentation suggests that embedding time varies linearly with message length. The simulation results show that, the proposed system provides high level of security.","PeriodicalId":174192,"journal":{"name":"2015 International Conference on Communications and Signal Processing (ICCSP)","volume":"2012 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130884816","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 paper proposes a fast MRI Brain Image segmentation method based on Artificial Bee Colony (ABC) algorithm and Fuzzy-C Means (FCM) algorithm. The value in continuous gray scale interval is searched using threshold estimation. The optimal threshold value is searched with the help of ABC algorithm. In order to get an efficient fitness function for ABC algorithm the original image is decomposed by discrete wavelet transforms. Then by performing a noise reduction to the approximation image, a filtered image reconstructed with low-frequency components, is produced. The FCM algorithm is used for clustering the segmented image which helps to identify the brain tumor.","PeriodicalId":174192,"journal":{"name":"2015 International Conference on Communications and Signal Processing (ICCSP)","volume":"48 17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133319933","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 resultant fused image provides a more accurate description than any of the individual source images. In this paper a novel multi focus image fusion method is presented by combining Discrete Wavelet Transform and Stationary Wavelet Transform. The source images are decomposed using wavelet transforms and the coefficients are fused according to the fusion rule. An informative fused image is obtained by performing the inverse wavelet transforms to the fused coefficients. The proposed framework is evaluated by employing parameters such as RMSE, PSNR, SF and Entropy. The simulation results demonstrate both quantitatively and subjectively that the proposed fusion approach is effective and can provide better performance in fusing multi-focus images than other conventional state of art single transform methods in the literature.","PeriodicalId":174192,"journal":{"name":"2015 International Conference on Communications and Signal Processing (ICCSP)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133231163","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}

APD's gain is highly sensitive to temperature. Hence, temperature of the APD needs to be controlled to get accurate & steady results. This paper proposes a Peltier element based Thermoelectric Cooler (TEC) system for precise temperature control. The design electronics system provides precise control by using PID based close loop system. A commercial available integrated TEC controller MAX1978 is considered for this purpose. This controller provides heating or cooling based on error between set temperature and measured temperature. A negative temperature coefficient (NTC) based Thermistor element is used for temperature measurement. This element is used in a bridge network and provides continuous feedback to controller. Developed electronics is evaluated with simulated load. With hardware test results, short term stability of 70mK is achieved. Peak power drawn by Peltier element is measured nearly 4W.","PeriodicalId":174192,"journal":{"name":"2015 International Conference on Communications and Signal Processing (ICCSP)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128892557","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 basic idea is to gather edge information from the source images and then segment the source images into blocks using the soft blending technique instead of cutting it into simple blocks. The differences between the edge information from both the source images is computed and the mean of these differences is set as the adaptive threshold. The differences obtained from each block are compared with this adaptive threshold and only those blocks for which the difference exceeds the threshold are chosen and incorporated into the final fused image. A further enhancement is achieved by making this process iterative. In every next iteration, the image is divided such that each block is subdivided by twice the number of divisions used in the last iteration. Also the number of iterations is fixed to 100. The performance of this method has been tested on many pairs of multifocus images and has shown promising results on comparison with existing methods.","PeriodicalId":174192,"journal":{"name":"2015 International Conference on Communications and Signal Processing (ICCSP)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115667800","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}
