Iterative Residual Fitting for Spherical Harmonic Transform of Band-Limited Signals on the Sphere: Generalization and Analysis
Usama Elahi, Zubair Khalid, Rodney A. Kennedy +1
We present the generalized iterative residual fitting (IRF) for the computation of the spherical harmonic transform (SHT) of band-limited signals on the sphere. The proposed method…
Optimal-Dimensionality Sampling on the Sphere: Improvements and Variations
Wajeeha Nafees, Zubair Khalid, Rodney A. Kennedy +1
For the accurate representation and reconstruction of band-limited signals on the sphere, an optimal-dimensionality sampling scheme has been recently proposed which requires the op…
Accurate Reconstruction of Finite Rate of Innovation Signals on the Sphere
Yahya Sattar, Zubair Khalid, Rodney A. Kennedy
We develop a method for the accurate reconstruction of non-bandlimited finite rate of innovation signals on the sphere. For signals consisting of a finite number of Dirac functions…
Gauss-Legendre Sampling on the Rotation Group
Zubair Khalid, Salman Durrani, Rodney A. Kennedy +2
We propose a Gauss-Legendre quadrature based sampling on the rotation group for the representation of a band-limited signal such that the Fourier transform (FT) of a signal can be…
Spherical Harmonic Expansion of Fisher-Bingham Distribution and 3D Spatial Fading Correlation for Multiple-Antenna Systems
Yibeltal F. Alem, Zubair Khalid, Rodney A. Kennedy
This paper considers the 3D spatial fading correlation (SFC) resulting from an angle-of-arrival (AoA) distribution that can be modelled by a mixture of Fisher-Bingham distributions…
An Optimal-Dimensionality Sampling Scheme on the Sphere with Fast Spherical Harmonic Transforms
Zubair Khalid, Rodney A. Kennedy, Jason D. McEwen
We develop a sampling scheme on the sphere that permits accurate computation of the spherical harmonic transform and its inverse for signals band-limited at using only sa…
