Recently, protection of digital audio signals has taken a great attention from the researchers. This paper proposed a new audio watermarking scheme based on Discrete Wavelet Transform (DWT), Singular Value Decomposition (SVD), and Quantization Index Modulation (QIM) with synchronization code embedded within double encrypted watermark images or logos into stereo audio signal. In the algorithm, an original audio signal is split into blocks and each block is decomposed into two levels discrete wavelet transform, and then the approximate low frequency sub-band coefficients are decomposed by the SVD transform, obtaining a diagonal matrix. The prepared watermarking and synchronization code bit stream is embedded into the diagonal matrix using Quantization Index Modulation (QIM). After that, we apply ISVD and IDWT to obtain the watermarked audio signal. The watermark can be blindly extracted without knowledge of the original audio signal. Experimental results show that the transparency and imperceptibility of the proposed algorithm is satisfactory, and robustness is strong against popular audio signal processing attacks. High watermark payload is achieved and performance analysis is presented.","PeriodicalId":362288,"journal":{"name":"2016 Fourth International Japan-Egypt Conference on Electronics, Communications and Computers (JEC-ECC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126873240","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}

This paper presents a practical generator of heart sounds and murmurs for educational and research purposes. The developed generator produces graphical representations of normal and two diseased heart sounds; namely aortic stenosis and mitral insufficient. Three datasets of real heart sounds have been preprocessed using discrete wavelet transform, in order to reduce the noise and decompose these cardiac signals to the third approximated level based on Daubechies four-coefficient wavelet. For the design and implementation of the heart sounds generator, the ATmega 2560 microcontroller was used to produce the output of all preprocessed datasets. The developed embedded generator showed successfully different cases of the heart sounds and murmurs, allowing to be used further for evaluating new automatic classification methods of cardiac valve abnormalities.","PeriodicalId":362288,"journal":{"name":"2016 Fourth International Japan-Egypt Conference on Electronics, Communications and Computers (JEC-ECC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130298085","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}

To deny the radar detection, the jammer should use high jamming power to overcome this high processing gain which increases the required Jamming-to-Signal Ratio (JSR) is, in most cases, extravagant and unachievable. This paper introduces a novel jamming technique designated as bandwidth shift jamming. The proposed jamming technique generates a replica of the intercepted radar signal but with a small shift in bandwidth. Jamming effectiveness of the proposed technique is evaluated on a typical modern search radar model with three different types of detectors: fixed threshold, Cell Average and Greatest Of Constant False Alarm Rate (CA-CFAR, GO-CFAR). Moreover, matched filter response to the proposed jamming signal is determined and the optimum parameters of the jamming signal are identified to maximize jamming effectiveness. The results show that the proposed jamming technique needs a JSR of -6 dB at least to be effective against LFM-PC search radar.","PeriodicalId":362288,"journal":{"name":"2016 Fourth International Japan-Egypt Conference on Electronics, Communications and Computers (JEC-ECC)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117139458","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}
