چکیده
When one imposes a nonnegativity constraint, one usually can reconstruct a two-dimensional sequence of finite support from themodulus of itsFourier transform using an iterativealgorithm, even when the initial estimate is an array of random numbers. In a recent paper,‘ the description of an iterative algorithm foreconstruct ing a sequencefromthe magnitudeof itsFourier transform unintentionally gives the appearance of dis-cussinganalgorithmpublishedearlier[ I ] .

One Dimensional Tdm Signal Reconstruction from Its Fourier Transform Phase or Magnitude
Unlike multidimensional signals, reconstruction of one dimensional signals from their Fourier phase or magnitude is faced with an inherent dilemma. In this paper, the reconstruction of 1D Time Division Multiplexing (TDM) signals (which are sparse in time) is discussed. We will show that such signals can be uniquely reconstructed from their Fourier phase; on the other hand, reconstruction from t...
متن کاملEffects of noise on signal reconstruction from Fourier transform phase
The effects of noise in the given phase o oignal reconstruction from the Fourier transform ohase are studied. Specifically, the effects of different methods of sampling the degraded phase, of the number of non—zero points in the sequence, and of the noise levol on the sequence reconstruction are examined. A sampling method is developef to significantly reduce the error in the reconstructed sequ...
متن کاملOn The Simulation of Partial Differential Equations Using the Hybrid of Fourier Transform and Homotopy Perturbation Method
In the present work, a hybrid of Fourier transform and homotopy perturbation method is developed for solving the non-homogeneous partial differential equations with variable coefficients. The Fourier transform is employed with combination of homotopy perturbation method (HPM), the so called Fourier transform homotopy perturbation method (FTHPM) to solve the partial differential equations. The c...
متن کاملAssessment of the Wavelet Transform for Noise Reduction in Simulated PET Images
Introduction: An efficient method of tomographic imaging in nuclear medicine is positron emission tomography (PET). Compared to SPECT, PET has the advantages of higher levels of sensitivity, spatial resolution and more accurate quantification. However, high noise levels in the image limit its diagnostic utility. Noise removal in nuclear medicine is traditionally based on Fourier decomposition o...
متن کاملAn Novel FFT Based Error Reduction Algorithm For Textured Image
This paper presents a reconstruction of missing textures based on error reduction algorithm using fourier transform magnitude estimation method. In this method fourier transform magnitude is estimated for a target patch including missing areas, and the missing intensities are estimated by retrieving its phase based on error reduction algorithm. In this method the errors are monitoring in the er...
