An Optimal-Dimensionality Sampling for Spin- Functions on the Sphere
Usama Elahi, Zubair Khalid, Rodney A. Kennedy +1
For the representation of spin- band-limited functions on the sphere, we propose a sampling scheme with optimal number of samples equal to the number of degrees of freedom of th…
Efficient sampling and robust 3D diffusion magnetic resonance imaging signal reconstruction
Alice P. Bates, Zubair Khalid, Jason D. McEwen +3
This paper presents novel single and multi-shell sampling schemes for diffusion MRI. In diffusion MRI, it is paramount that the number of samples is as small as possible in order t…
Symbol-by-Symbol Maximum Likelihood Detection for Cooperative Molecular Communication
Yuting Fang, Adam Noel, Nan Yang +2
In this paper, symbol-by-symbol maximum likelihood (ML) detection is proposed for a cooperative diffusion-based molecular communication (MC) system. In this system, the transmitter…
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…
An Optimal Dimensionality Multi-shell Sampling Scheme with Accurate and Efficient Transforms for Diffusion MRI
Alice P. Bates, Zubair Khalid, Jason D. McEwen +1
This paper proposes a multi-shell sampling scheme and corresponding transforms for the accurate reconstruction of the diffusion signal in diffusion MRI by expansion in the spherica…
