By the help of this derived MGF expression, we analyze the average symbol error rate (ASER) over independent and identical distributed (i.i.d) Weibull fading channels for multiple relays. The numerical values of ASER expression is compared with Monte-Carlo simulation result to verify the accuracy of the derivation.","PeriodicalId":318875,"journal":{"name":"2015 International Conference on Signal Processing and Communication (ICSC)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127347706","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}

Talwar","doi":"10.1109/ICSPCOM.2015.7150661","DOIUrl":"https://doi.org/10.1109/ICSPCOM.2015.7150661","url":null,"abstract":"Remotely sensed data is only a key source of detection of Earth's surface changes or Land-Use/Land-Cover (LULC) monitoring. During past decades, a series of effective change detection techniques such as Principal Component Analysis (PCA), Change Vector Analysis (CVA) and Post Classification Comparison (PCC), have been developed to observe the LULC vicissitudes. All aforesaid techniques performed very well in some situations such as on horizontal land but very rarely experimented on rugged terrain satellite imagery because change detection procedures are very problematic for such study areas. From this perspective, this study comprises the quantitative analysis of different change detection techniques to study LULC changes linked with rugged terrain Moderate Resolution Imaging Spectroradiometer (MODIS) sensor satellite imagery. In addition to this, necessary pre-processing steps such as geometric correction, radiometric correction and topographic correction for flat surface as well as rugged terrain, have also been summarized to correct the estimated spectral reflectance value. Experiment outcomes confirms that CVA technique has greater potential (achieved accuracy assessment of 90% with Kappa coefficient of 0.8838) than PCC and PCA techniques (achieved accuracy assessment of 78-82% with Kappa coefficient of 0.6358-0.7537, respectively) to analyzed the overall transformed information over rugged terrain MODIS satellite imagery. It is projected that this will efficiently guide the natural hazard forecaster's or algorithm engineer's to precisely perceive the multi-temporal environment changes over Land-Use/Land-Cover rugged terrain.","PeriodicalId":318875,"journal":{"name":"2015 International Conference on Signal Processing and Communication (ICSC)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122117824","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}

Modern communication demands high speed data processing at nanometer wavelength and it is basically relying on the speed and bandwidth of emitters & detectors on the nanoscale. In order to achieve this goal, antenna made of material with high permittivity and permeability dielectrics are required which allow the enhancement of light and high frequency RF communication and sensing. Optical Yagi-Uda nantenna offers unique directive property which mobilizes concept like beam forming and beam scattering and can be predominately useful in various application areas. To fulfill this motive we need to study suitable material technology in order to improve various properties such as gain, return loss, radiated power etc. ANSYS HFSS v15.0 is the software that provides a platform to design the antenna with the changes in dielectric permittivity and permeability and the spacing between the elements is relying on the operating wavelength.","PeriodicalId":318875,"journal":{"name":"2015 International Conference on Signal Processing and Communication (ICSC)","volume":"26 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":"125185775","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 the design of an antenna that is conformal on a spherical surface viz. radome, an integral part of the aircraft structure and does not cause extra drag.

For every new design same formulae are used which is time consuming and lengthy. The Bhatnagar's Postulate gives the idea of transforming one design into another by using normalized thickness H (ratio of height of substrate to guided wavelength) and scaling factor ψ (ratio of the square root of the dielectric constant of the first design to second). But it is limited to patch only. This paper uses the same principle for calculating new formulae for the feed line dimensions. The first antenna design dimensions are calculated by classical formulae and then others are simulated with the new formulae of feed line dimensions, Bhatnagar's Postulate for the patch and the calculations of the first design. This gives very good results.","PeriodicalId":318875,"journal":{"name":"2015 International Conference on Signal Processing and Communication (ICSC)","volume":"10 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":"126789615","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}

Then nonlinear mapping was applied to find the principal components for the wavelet features using kernel PCA. For image matching k-nearest neighbor's classifier has been used.

The aim was to develop an autonomous flying quad-copter for indoor applications. The approach has been implemented and tested in variety of environments consisting of obstacles of varying heights and dimly-lit conditions. Indoor applications present a major problem of space limitation. Without carefree maneuvering, one might end up hurting oneself or damaging the quad-copter. Using ultrasonic sensors, this problem can be eliminated to an appreciable extent. A hardware design has been proposed after testing and experimentation, followed by an algorithm for computer assisted maneuvering in static indoor environment.
