An Invitation to Hypercomplex Phase Retrieval: Theory and Applications

no code implementations20 Oct 2023 Roman Jacome, Kumar Vijay Mishra, Brian M. Sadler, Henry Arguello

The hypercomplex PR (HPR) arises in many optical imaging and computational sensing applications that usually comprise quaternion and octonion-valued signals.

LD-GAN: Low-Dimensional Generative Adversarial Network for Spectral Image Generation with Variance Regularization

2 code implementations29 Apr 2023 Emmanuel Martinez, Roman Jacome, Alejandra Hernandez-Rojas, Henry Arguello

To surmount this limitation, we propose low-dimensional GAN (LD-GAN), where we train the GAN employing a low-dimensional representation of the {dataset} with the latent space of a pretrained autoencoder network.

Multi-Antenna Dual-Blind Deconvolution for Joint Radar-Communications via SoMAN Minimization

no code implementations23 Mar 2023 Roman Jacome, Edwin Vargas, Kumar Vijay Mishra, Brian M. Sadler, Henry Arguello

Our theoretical analyses show that the minimum number of samples and antennas required for perfect recovery is logarithmically dependent on the maximum of the number of radar targets and communications paths rather than their sum.

D$^\text{2}$UF: Deep Coded Aperture Design and Unrolling Algorithm for Compressive Spectral Image Fusion

no code implementations24 May 2022 Roman Jacome, Jorge Bacca, Henry Arguello

To overcome this issue, compressive spectral image fusion (CSIF) employs the projected measurements of two CSI architectures with different resolutions to estimate a high-spatial high-spectral resolution.

Joint Radar-Communications Processing from a Dual-Blind Deconvolution Perspective

no code implementations11 Nov 2021 Edwin Vargas, Kumar Vijay Mishra, Roman Jacome, Brian M. Sadler, Henry Arguello

When the radar receiver is not collocated with the transmitter, such as in passive or multistatic radars, the transmitted signal is also unknown apart from the target parameters.
