Hybrid Beamforming for Active Sensing using Sparse Arrays
Robin Rajamäki, Sundeep Prabhakar Chepuri, Visa Koivunen
This paper studies hybrid beamforming for active sensing applications, such as millimeter-wave or ultrasound imaging. Hybrid beamforming can substantially lower the cost and power…
Generative Adversarial Networks For Graph Data Imputation From Signed Observations
Amarlingam Madapu, Santiago Segarra, Sundeep Prabhakar Chepuri +1
We study the problem of missing data imputation for graph signals from signed one-bit quantized observations. More precisely, we consider that the true graph data is drawn from a d…
Learning product graphs from multidomain signals
Sai Kiran Kadambari, Sundeep Prabhakar Chepuri
In this paper, we focus on learning the underlying product graph structure from multidomain training data. We assume that the product graph is formed from a Cartesian graph product…
Sampling And Reconstruction Of Diffusive Fields On Graphs
Siddartha Reddy, Sundeep Prabhakar Chepuri
In this paper, the focus is on the reconstruction of a diffusive field and the localization of the underlying driving sources on arbitrary graphs by observing a significantly small…
Analog Beamforming for Active Imaging using Sparse Arrays
Robin Rajamäki, Sundeep Prabhakar Chepuri, Visa Koivunen
This paper studies analog beamforming in active sensing applications, such as millimeter-wave radar or ultrasound imaging. Analog beamforming architectures employ a single RF-IF ch…
Sensor Placement and Resource Allocation for Energy Harvesting IoT Networks
Osama M. Bushnaq, Anas Chaaban, Sundeep Prabhakar Chepuri +2
The paper studies optimal sensor selection for source estimation in energy harvesting Internet of Things (IoT) networks. Specifically, the focus is on the selection of the sensor l…
