GLRT for Reconfigurable Intelligent Surface aided Spectrum Sensing
Nikhilsingh Parihar, Praful Mankar, Sachin Chaudhari
Spectrum sensing (SS) is crucial for realising cognitive radio networks, where the secondary user (SU) needs to detect the presence of a primary user (PU) in order to utilise the s…
Near-field Wideband Multi-User Localization using NFMR-Net
Pearl Hetul Shah, Srikar Sharma Sadhu, Praful D. Mankar
This paper proposes a deep learning based method for wideband near-field multi-user localization. In particular, the proposed approach utilizes the Zadoff-Chu (ZC) sequence based p…
Near-field Anchor-free Localization using Reconfigurable Intelligent Surfaces
Srikar Sharma Sadhu, Praful D. Mankar, Santosh Nannuru
Near-field localization is expected to play a crucial role in enabling a plethora of applications under the paradigm of 6G networks. The conventional localization methods rely on c…
Time-Frequency Pilot Sequence Design and LoS Delay-Doppler Estimation
Aadarsh Devanand, Praful D. Mankar
We present a novel framework for line-of-sight (LoS) delay-Doppler (DD) estimation in dense scattering propagation environments. We present two time-frequency (TF) domain pilot seq…
Near-field 5D Pose Estimation using Reconfigurable Intelligent Surfaces
Srikar Sharma Sadhu, Praful D. Mankar, Santosh Nannuru
The advent of 6G is expected to enable many use cases which may rely on accurate knowledge of the location and orientation of user equipment (UE). The conventional localization met…
Maximum Eigenvalue Detection based Spectrum Sensing in RIS-aided System with Correlated Fading
Nikhilsingh Parihar, Praful D. Mankar, Sachin Chaudhari
Robust spectrum sensing is crucial for facilitating opportunistic spectrum utilization for secondary users (SU) in the absense of primary users (PU). However, propagation environme…
