Color holographic reconstruction using multiple SLMs and LED illumination
(SPIE, 2009-01)A color holographic reconstruction technique by using three light emitting diodes (LEDs) is described. Reflective type phase-only spatial light modulators (SLMs) are used since they are suitable for in-line phase holograms. ... -
Çok kullanıcılı çok antenli sistemlerde iş birlikli iletim
(IEEE, 2008-04)Bu çalışmada işbirlikli, çok kullanıcılı, ve çok antenli bir haberleşme sisteminde telsiz erişim terminallerinin en iyi veri iletimi tekniğine ortaklaşa karar vermeleri problemini inceliyoruz. Burada pek çok çalışmadan ... -
Downlink beamforming under individual SINR and per antenna power constraints
(IEEE, 2007-08)In this paper we consider the problem of finding the optimum beamforming vectors for the downlink of a multiuser system, where there are individual signal to interference plus noise ratio (SINR) targets for each user. ... -
Efficient solution of the electric-field integral equation using the iterative LSQR algorithm
(Institute of Electrical and Electronics Engineers, 2008)In this letter, we consider iterative solutions of the three-dimensional electromagnetic scattering problems formulated by surface integral equations. We show that solutions of the electric-field integral equation (EFIE) ... -
Iterative solution of the normal-equations form of the electric-field integral equation
(IEEE, 2007)In this paper, we show that transforming the original equations into normal equations improves the convergence of EFIE significantly. We present the solutions of EFIE by employing the least-squares QR (LSQR) algorithm, ... -
Preconditioned MLFMA solution of multiple dielectric-metallic composite objects with the electric and magnetic current combined-field integral equation (JMCFIE)
(IEEE, 2009-06)We consider fast and accurate solutions of scattering problems involving multiple dielectric and composite dielectric-metallic structures with three-dimensional arbitrary shapes. Problems are formulated rigorously with the ... -
Signal recovery from partial fractional fourier transform information
(IEEE, 2004)The fractional Fourier transform has found many applications in signal and image processing and optics. An iterative algorithm for signal recovery from partial fractional Fourier transform information is presented. The ... -
Three-dimensional motion and dense-structure estimation using convex projections
(SPIE, 1997-02)We propose a novel method for estimating the 3D motion and dense structure of an object form its two 2D images. The proposed method is an iterative algorithm based on the theory of projections onto convex sets (POCS) that ...
