The raw ECG signal is first digitalized by passing it through an analog to digital converter (ADC), then a Wavelet decomposer is used for the decomposition of the signal into four Wavelet Filter Banks. A Noise detector is connected to the output of one of the Wavelet Filter Bank (#one) and works as an input to the QRS Complex detector. The QRS Complex detector consists of Multi Scaled product and Soft Threshold algorithms. On the basis of noise information obtained from the noise detector, the Multi Scaled Product algorithm selects the outputs of Wavelet Filter Banks and Multiply these using a radix-4 Booth multiplier for the detection of QRS Complex wave. The Soft Threshold algorithm is used to increase the accuracy of the QRS Complex detection. The proposed QRS complex detector is simulated using ModelSim simulator and synthesized on Xilinx SPARTAN-6 FPGA using Project Navigator version 6.1i. Obtained results show that the proposed QRS detector is lesser complex and its overall delay is reduced by 33% compared to the previously designed QRS complex detectors.","PeriodicalId":318875,"journal":{"name":"2015 International Conference on Signal Processing and Communication (ICSC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124499364","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}

Here the emphasis is made on channel negotiation, it helps to improve the spectrum management. A dynamic MCMC (Markov Chain Monte Carlo) approach is used to resolve the optimization problem for channel selection. In addition, this work offers a suite of mechanisms for the implementation of the principles proposed, including segmentation of long packets and arbitration that controls on power request-to-send function (RTS) and Clear-to-Send (CTS) level in a multi-channel environment. Here cyclostationary detection technique which at beginning will sense the channel and filter them for the further use, this way it will make the channel negotiation and access scheme to work more efficiently. Th NS-2 simulation is used to analyze the result with respect to proposed approach and examine its performance. It is observed that proposed mechanism can prove to be eminent that to the predefined control channels existing in the CR networks.","PeriodicalId":318875,"journal":{"name":"2015 International Conference on Signal Processing and Communication (ICSC)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133740669","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}

For performance evaluation, all objective speech quality assessment algorithms require the Mean Opinion Score-Listening Quality Subjective (MOS-LQS) or subjective MOS obtained from the subjective listening test for comparison with the Mean Opinion Score-Listening Quality Objective (MOS-LQO) or objective MOS. This paper gives details of the subjective database created for the different applications. In this work, subjective speech quality assessment has been done for speech utterances at different degradation/noise conditions to assign the MOS-LQS or subjective MOS and compared with MOS-LQO or the objective MOS obtained from an algorithm based on relevant auditory perception features for an illustration. Two different databases NOIZEUS-960 and NOIZEUS-2240 having 3200 speech utterances processed by different speech enhancement algorithms at different types of real life noise conditions have been used for subjective listening test by real life users. The statistical analysis of the MOS-LQS assigned by different subjects for different degraded speech utterances has been done and its details are reported in the paper. Further, the correlation coefficients are computed between the subjective MOS and the objective MOS for both the databases for an illustration and inferences are drawn regarding the usefulness of the subjective MOS in speech quality assessment algorithms.","PeriodicalId":318875,"journal":{"name":"2015 International Conference on Signal Processing and Communication (ICSC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114668774","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}
