In the novel spherical harmonic algorithm, the received microphone signals are firstly used to do the spherical Fourier transform. Then, the MUSIC algorithm is applied to the spherical components to obtain the angularspectrum. Finally, the angular-spectrum smoothing technique is initially proposed to obtain the accuracy localization for wideband sources. In contrast to the traditional single spherical array the multiple spherical arrays used in this paper consist of several randomly distributed spheres in a given plane. The microphones are uniformly placed on each sphere, the same as the usual single spherical array. Simulation comparison of wideband sources localization between single spherical array and multiple spherical array based on the novel algorithm is carried out to evaluate the validity of our method.","PeriodicalId":88960,"journal":{"name":"Proceedings of the ...

To mitigate this effect, computational demanding equalization schemes that require the inversion of the channel matrix, should be applied. In order to achieve linear complexity in the number of the subcarriers, a banded approximation of the channel matrix is usually adopted, whereas the performance of the equalizer is significantly degraded. To recover this performance loss, we propose a regularized estimation framework for MMSE ICI equalization in the frequency domain, where the complexity remains linear with respect to the number of the subcarriers. Simulation results verify the effectiveness of the proposed regularization.","PeriodicalId":88960,"journal":{"name":"Proceedings of the ...

Compared to their all-optical counterparts, electronic compensation increases flexibility and gives a new impetus to transparent optical networks for adaptive and dynamic handling in cases where the total accumulated dispersion is not known in advance. In this paper, the Sparse Learning via Iterative Minimization (SLIM) algorithm is employed for the design of reduced size Volterra Decision Feedback (VDFE) equalizers in the context of optical communications is considered. The equalizer structure is dynamically tuned discarding coefficients that have a marginal contribution to the performance of the equalizer leading to both enhanced convergence speed and significant computational complexity savings.","PeriodicalId":88960,"journal":{"name":"Proceedings of the ...

A new approach for geometrical corrections and noise cancelations of the turbulence degraded frames of a video is presented. The time-averaged frame of the video is used to overcome the geometric deformations through an iterative robust image registration technique. The results of the registration are geometrically corrected frames which still contain noise. A non-local means filter is used to extract the noise from the individual frames. A performance comparison between our proposed restoration approach and the earlier First Register Then Average And Subtract (FRTAAS) approach is presented in terms of restoration accuracy. The effectiveness of our approach is demonstrated on both synthetic and real-world surveillance videos.","PeriodicalId":88960,"journal":{"name":"Proceedings of the ...

Back-projection has been customized to make it work even when the projections are not uniformly distributed, and thus ensures a better initial guess to start ART iterations. Contour information of the object has been used efficiently for faster and finer reconstruction. Aiming successful reconstruction with minimum number of iterations, conjugate gradient method that enjoys the full benefit of ART with good initial guess has been used instead of commonly used steepest descent method. Based on the experiments on simulated and real medical images it has been shown that the proposed modality is capable of producing much better reconstruction than the state-of-the-art methods.","PeriodicalId":88960,"journal":{"name":"Proceedings of the ...

EOG can make serious problems in results and interpretations of EEG processing. Rejecting contaminated EEG segments result in an unacceptable data loss. Many methods were proposed to correct EOG artifact mainly based on regression and blind source separation (BSS). In this study, we proposed an automatic correction method based on maximum likelihood estimation. The proposed method was applied to our simulated data (real artifact free EEG plus controlled EOG) and results show that this method gives superior performance to Schlögl and SOBI methods.","PeriodicalId":88960,"journal":{"name":"Proceedings of the ...
