Coded Aperture Radar Imaging Using Reconfigurable Intelligent Surfaces
R. S. Prasobh Sankar, Sundeep Prabhakar Chepuri
In this paper, we focus on radar imaging using active sensing with a single transceiver and reconfigurable intelligent surface (RIS). RISs are arrays with tunable passive phase shi…
Quantized Precoding and RIS-Assisted Modulation for Integrated Sensing and Communications Systems
R. S. Prasobh Sankar, Sundeep Prabhakar Chepuri
In this paper, we present a novel reconfigurable intelligent surface (RIS)-assisted integrated sensing and communication (ISAC) system with 1-bit quantization at the ISAC base stat…
Joint Communication and Radar Sensing with Reconfigurable Intelligent Surfaces
R. S. Prasobh Sankar, Battu Deepak, Sundeep Prabhakar Chepuri
In this paper, we use a reconfigurable intelligent surface (RIS) to enhance the radar sensing and communication capabilities of a mmWave dual function radar communication system. T…
Channel Estimation for RIS-assisted Millimeter-wave MIMO Systems
Battu Deepak, R. S. Prasobh Sankar, Sundeep Prabhakar Chepuri
Channel estimation in reconfigurable intelligent surface (RIS) assisted multiple input multiple output (MIMO) communication systems is challenging as pilots cannot be decoded at or…
Millimeter Wave MIMO Channel Estimation with 1-bit Spatial Sigma-delta Analog-to-Digital Converters
R. S. Prasobh Sankar, Sundeep Prabhakar Chepuri
This paper focuses on channel estimation for mmWave MIMO systems with 1-bit spatial sigma-delta analog-to-digital converters (ADCs). The channel estimation performance with 1-bit s…
