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 k-angle tight frames
Somantika Datta, Jesse Oldroyd
Frames have become standard tools in signal processing due to their robustness to transmission errors and their resilience to noise. Equiangular tight frames (ETFs) are particularl…
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…
Geometry of the Welch Bounds
Somantika Datta, Stephen Howard, Douglas Cochran
A geometric perspective involving Grammian and frame operators is used to derive the entire family of Welch bounds. This perspective unifies a number of observations that have been…
