Due to the Federal communication commission's power limitation on the transmitting signal at transmitter, the receiver signal power of the UWB system is very smaller than interferer narrow-band signals. To avoid this interference and to get the original received signal at receiver side the characteristic of interference rejection must be at receiver. As the low noise amplifier is very first stage of the receiver, here in this paper we proposed a wide-band input network with out-band rejection capability to suppress the out-band properties as its first stage of LNA. Source degenerated cascode Amplifier is used as the amplifier stage of LNA. To attenuate more the out-band rejection characteristic without influencing the input matching, a dual band Notch filter with the low noise Active Inductor is used as the second stage. An Active Inductor circuit has been designed to modify with respect to improve its Quality factor as well as to reduce its noise, as comparatively an Active Inductor has lowered the noise performance than the Passive Inductors. There is maximum 75-85 dB out-band rejection has been measure with the power gain of almost 15dB and 0.9 nV/sqrt(Hz) the minimum power spectral density has been measured while consuming a DC power of 4.7mW.","PeriodicalId":432479,"journal":{"name":"2015 International Conference on Signal Processing and Communication Engineering Systems","volume":"315 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123405326","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}

WMNs provide a good platform for many researchers to develop new innovative procedures and methods to improve the network performance in wireless enterprise backbone networks. WMNs have unique features like ease of deployment at low cost. By adding multiple radios and multiple channels, it is possible to improve the network capacity and throughput. Due to the scarcity of non-overlapped frequency channels and available radios per node, the interference is still present, which limits the bandwidth available on network links and eventually degrades the achievable throughput. As interference depends on how channels are bound to radio interfaces, a proper channel assignment scheme is needed to reduce the interference. The Interference Minimization is one of the major problems in Multi Radio and Multi-channel WMNs. In this paper, we propose a BFS-Maximum Neighbor Index based Channel Assignment (BFS-MaxNICA) algorithm to improve the overall network performance by decreasing the interference degree. The simulation results show that proposed scheme outperforms the earlier approaches like Clique and CCA (Centralized channel Assignment) Algorithms.","PeriodicalId":432479,"journal":{"name":"2015 International Conference on Signal Processing and Communication Engineering Systems","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129831189","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}

However, there are still some concerns about reinforced polymers due to their manufacturing imperfection or imperfections during their in-service, such as the presence of surface and sub-surface defects which effect their performance. InfraRed Thermography (IRT) shows its potential usage for non-destructive testing and evaluation (NDT&E) due to its intrinsic testing capabilities such as remote, whole field, quantitative and qualitative to detect surface and sub-surface defects. This present work highlights a spectral reshaping by introducing a Gaussian window on the captured thermal profile in a frequency modulated thermal wave imaging and named as Gaussian Windowed Frequency Modulated Thermal Wave Imaging (GWFMTWI) technique. Further various multi-transform techniques (time and frequency domain based) have been introduced in order to test sub-surface defect detection capabilities in chosen GFRP sample. Comparison has been made with the non-stationary linear frequency modulated thermal wave imaging technique in terms of depth scanning capability. Results obtained from the GWFMTWI clearly shows better detection potential with improved test resolution and sensitivity.","PeriodicalId":432479,"journal":{"name":"2015 International Conference on Signal Processing and Communication Engineering Systems","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127377306","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}
