Deep uGMRT observations for enhanced calibration of 21 cm arrays -- I. First image and source catalogue
Khandakar Md Asif Elahi, Samir Choudhuri, Nirupam Roy +3
Radio-interferometric arrays require very precise calibration to detect the Epoch of Reionization 21-cm signal. A remarkably complete and accurate sky model is therefore needed in…
DeepSync: A Learning Framework for Pervasive Localization using Code Synchronization on Compressed Cellular Spectrum
Aritrik Ghosh, Nakul Garg, Nirupam Roy
Pervasive localization is essential for continuous tracking applications, yet existing solutions face challenges in balancing power consumption and accuracy. GPS, while precise, is…
Spatial Audio Processing with Large Language Model on Wearable Devices
Ayushi Mishra, Yang Bai, Priyadarshan Narayanasamy +2
Integrating spatial context into large language models (LLMs) has the potential to revolutionize human-computer interaction, particularly in wearable devices. In this work, we pres…
SpINR: Neural Volumetric Reconstruction for FMCW Radars
Harshvardhan Takawale, Nirupam Roy
In this paper, we introduce SpINR, a novel framework for volumetric reconstruction using Frequency-Modulated Continuous-Wave (FMCW) radar data. Traditional radar imaging techniques…
Simultaneously Learning Speaker's Direction and Head Orientation from Binaural Recordings
Harshvardhan Takawale, Nirupam Roy
Estimation of a speaker's direction and head orientation with binaural recordings can be a critical piece of information in many real-world applications with emerging `earable' dev…
