So we can't allot spectrum to all the users. The unlicensed users along with licensed users try to occupy the spectrum at a time. Because of this interference will occur when the information is shared between both unlicensed and licensed in the same time period. We have to reduce interference when spectrum is occupied because there is a difficulty in maintaining the expected quality of service for unlicensed users. In this paper we use distributed dynamic spectrum protocol in which both licensed and unlicensed users oppurtunistically operate spectrum at a time. At first channel gain estimates are used to set feasible transmit powers for unlicensed users i.e., device-to-device users here to keep the interference they cause within the allowed interference temperature. Then network information is used when the packets are sent from source to destination. Using network information we can establish either single-hop route or multi-hop route when the data is transferred using route discovery packets. This network information in discovery packet will help reduce the failure rate in discovering the route and also will help increase the percentage savings in the number of discovery transmissions. We will also make analysis to obtain the maximum possible packet delivery rate during the time when information is transferred.","PeriodicalId":174192,"journal":{"name":"2015 International Conference on Communications and Signal Processing (ICCSP)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131194458","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 realize MUTP using Zero Forcing (ZF)algorithm. In this paper, we consider turbo coded system to achieve high coding gain. We construct the turbo code using parallel concatenated convolutional encoder and certain bits are punctured periodically to achieve code rate ½. We construct the pre-processing matrix using channel state information of all the users. We evaluate the performance of such coded ZF-MUTP assisted IDMA system for realistic channel model based on SUI channel model specifications. From our simulations, we observe that the ZF-MUTP assisted multi-user IDMA system provides better performance in terms of bit error rate (BER) with low signal to noise ratio (SNR).","PeriodicalId":174192,"journal":{"name":"2015 International Conference on Communications and Signal Processing (ICCSP)","volume":"22 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":"114983701","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 filtered-X least mean square (FxLMS) algorithm is considered to be the best choice for its reduced complexity and robustness, especially for controller in adaptive filter. In this paper FxLMS algorithm is applied for narrow band noise. Also the system uses variable learning parameter (variable step size) to improve the convergence speed and reduction in noise. The objective of using variable step FxLMS (VSFxLMS) algorithm is to reduce the noise level in source with novel convergence speed in addition to secondary impulse response. Simulations are carried out using MATLAB. The reduction of noise in a narrow band is preferred so that effective and efficient noise control will be achieved and a comparative result with fixed step FxLMS (FSFxLMS) is shown.","PeriodicalId":174192,"journal":{"name":"2015 International Conference on Communications and Signal Processing (ICCSP)","volume":"36 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":"121367803","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}

Several techniques are proposed for measuring the image quality but any of this techniques is considered to be ideal for measuring the image quality. Image quality assessment plays a significant role in the field of image processing. Image quality assessment (IQA) estimates the quality of an image by measuring the difference between the reference and distorted images. Distortion estimation in objective domain also plays a significant role during IQA. There are three categories of IQA methods: full-reference (FR), partial or reduced-reference (RR), and no-reference (NR). Reduced reference image quality assessment (RR IQA) gives a realistic solution for automatic image quality estimation in different kinds of applications where only partial information of the original or reference image is available. The idea of RR IQA's to use less information about the image and obtain higher evaluation precision.","PeriodicalId":174192,"journal":{"name":"2015 International Conference on Communications and Signal Processing (ICCSP)","volume":"86 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":"125940951","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 attempts to study the performance of Text dependent speaker verification system using Delta-Delta Mel Frequency Cepstral Coefficients (MFCC-Δ-Δ) feature vector and Fuzzy C means (FCM) speaker modelling technique. Speaker-specific information which is mainly represented by spectral features, are used in respective models which serves as an important parameter for determining the claim of the speaker. The experimental results performed on microphonic database suggest that accuracy significantly depends on the value of learning parameter of the objective function of FCM. Our work focuses on total success rate or accuracy and the effect of learning parameter of FCM on improving the accuracy.","PeriodicalId":174192,"journal":{"name":"2015 International Conference on Communications and Signal Processing (ICCSP)","volume":"74 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":"123573328","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 scientific aspect of the temperature controlled environment is to bring down the error in radial velocity measurement to 1m/s. Radial velocity (RV) technique is used to determine various orbital parameters in exo-planet search. It has been found that temperature variation of 1°C at the spectrograph environment can increase the error in radial velocity measurement by few thousands of m/s. Mechanical flexures (in the scale of micrometers) in the optical components can increase the error by a significant percentage due to temperature and pressure variations. So the temperature stability is very important for the PARAS project. So high precision temperature logger with a high stability is designed for PARAS project with the help of LabVIEW.","PeriodicalId":174192,"journal":{"name":"2015 International Conference on Communications and Signal Processing (ICCSP)","volume":"7 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":"116454914","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}
