convolution transform
1.Identification of Daemonorops draco Bl. by near-infrared diffuse reflectance spectrometry combined with visualization of convolution transform
3.Using convolution and fast Fourier transform(FFT) algorithm to calculate diffraction integral,the CGH is reconstructed by digital focus method.
4.In this paper, algorithms for computing 2-D circular convolution by using Fast Polynomial Transform (FPT) are reviewed and discussed, and then an improved algorithm is presented.
5.Convolution of windowing function is traditionally used to explain the Discrete Fourier Transform(DFT) errors.
6.An approach is made to simplify the search procedures for optimum-excitation-selection in CELP coder by DFT (Discrete Fourier Transform); i. e. by making use of the transform domain method to simplify convolution operation.
7.According to the seismic convolution model, a kind of matched filters in time-scale domain is designed for echo signal detection of Ground Penetrating Radar (GPR) and implemented in this paper, which is applied to detect the location and amplitude of single reflection wavelet in receiving signal through continuous wavelet transform.
8.The prevailing approaches depend on costly time domain convolution, using the frequency domain network parameters such as S-parameter, Y-parameter or ABCD parameters to find analytic solution, and finding the time domain approximations by FFT or even numerical inversion of laplace transform (NITL) if there are a large number of nonlinear devices in the network.
