Wavelets for using Zernike polynomials
Somantika Datta, Kanti B. Datta
A set of orthogonal polynomials on the unit disk known as Zernike polynomials are commonly used in the analysis and evaluation of optical systems. Here Zernike polynomials…

Low coherence unit norm tight frames
Somantika Datta, Jesse Oldroyd
Equiangular tight frames (ETFs) have found significant applications in signal processing and coding theory due to their robustness to noise and transmission losses. ETFs are charac…

Construction of zero autocorrelation stochastic waveforms
Somantika Datta
Stochastic waveforms are constructed whose expected autocorrelation can be made arbitrarily small outside the origin. These waveforms are unimodular and complex-valued. Waveforms w…
