The wireless technology is growing rapidly and there is a growing demand of high performance, capacity and larger bit rate wireless communication systems which cope wireless communication services such as high speed data, video and voice signals. Multicarrier modulation scheme like OFDM provides an efficient solution to overcome this problem. In this paper a gray scale image processing is done using a LMS algorithm with wavelet based OFDM system using the QPSK modulation scheme in AWGN and Rayleigh channel in SISO environment and results are compared with the conventional adaptive FFT based OFDM system. We reconstruct our transmitted signal at receiver; in both systems by minimizing the error by adaptive filter but the computational complexity of FFT based system is more as compared to DWT based system. Results are compared in term of SNR vs BER which shows that adaptive DWT based OFDM system perform better as compared to the conventional adaptive FFT OFDM system.","PeriodicalId":344222,"journal":{"name":"2017 International Conference on Communication, Computing and Digital Systems (C-CODE)","volume":"53 49","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120809182","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 is one of the major issues in commercial and out of the lab usage of such systems. Common Spatial Pattern (CSP) algorithms are widely used for feature extraction in BCI systems for motor imagery. As the EEG signals have noise and overfitting issues, various regularized CSP algorithms are introduced to overcome these factors. In this work, a method is introduced to find the variant of CSP that achieves maximum classification accuracy with least number of EEG channels. The approach is based on firstly identify the spatial filter weights using complete set of channels. In the next step, the channels are selected based on the maximal filter weights. Channels with highest values are included to find the accuracy in next run and ultimately the optimum combination of number of channels, CSP variant and classification accuracy are reported. Multichannel data comprised of 60 electrodes from BCI Competition III dataset IIIa from three subjects who performed left hand, right hand, foot and tongue MI is considered for this purpose. For the data analyzed in this study, it is found that instead of using data from 60 electrodes only six can be used without significantly compromising the classification accuracy.","PeriodicalId":344222,"journal":{"name":"2017 International Conference on Communication, Computing and Digital Systems (C-CODE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122000814","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}

Non Contiguous orthogonal frequency division multiplexing (NCOFDM), a multicarrier system is considered as the appropriate candidate for CR physical layer, but due to its high sidelobes it suffers from high out of band (OOB) radiation, that can affect its spectrum sharing capability. In this paper, we proposed two search algorithms: Genetic Algorithm (GA) and Firefly algorithm (FFA) for estimating the amplitudes of the Cancellation subcarriers (CCs). These CCs are inserted on either side of the used NCOFDM signal to cancel the sidelobes. Simulation results show that better sidelobe reduction is achieved by the proposed algorithms as compared to the existing techniques in the literature.","PeriodicalId":344222,"journal":{"name":"2017 International Conference on Communication, Computing and Digital Systems (C-CODE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129928205","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}

Manual counting and conventional investigation of such histological tissues is quite laborious, time taking, less reliable, and subject to error. In order to achieve more accurate results as quickly as possible, the presented work devices a novel color scheme code (I4) from existing schemes (I1,I2,I3). Moreover the work offers an Automated Quantification technique for enumeration and segmentation of pancreatic mass from microscopic images. The technique includes five modules; (1) Segmentation to magnify Islet cells from the rest of mass, (2) Equalization uses Contrast-Limited Adaptive Histogram equalization method in order to enhance contrasts between different intensity levels, (3) Color Space Formation uses existing color spaces with proposed smart calculations to construct novel color space code, (4) Image Conversion applies novel color space code on the image followed by certain post processing (binarization, hole-filling, erosion), and (5) Cell Analysis uses connected component labeling to finally identify and label the cells. The technique is evaluated against a number of diverse microscopic images obtaining satisfactory empirical results with recognition confidence interval in terms of true positive, false positive, and false negative are respectively 97.75 ± 2.64, 1.79 ± 1.04, and 1.37 ± 0.84.
