Near-Field ISAC in 6G: Addressing Phase Nonlinearity via Lifted Super-Resolution
Sajad Daei, Amirreza Zamani, Saikat Chatterjee +2
Integrated sensing and communications (ISAC) is a promising component of 6G networks, fusing communication and radar technologies to facilitate new services. Additionally, the use…
DANSE: Data-driven Non-linear State Estimation of Model-free Process in Unsupervised Learning Setup
Anubhab Ghosh, Antoine Honoré, Saikat Chatterjee
We address the tasks of Bayesian state estimation and forecasting for a model-free process in an unsupervised learning setup. For a model-free process, we do not have any a-priori…
Observability-aware online multi-lidar extrinsic calibration
Sandipan Das, Ludvig af Klinteberg, Maurice Fallon +1
Accurate and robust extrinsic calibration is necessary for deploying autonomous systems which need multiple sensors for perception. In this paper, we present a robust system for re…
M-LIO: Multi-lidar, multi-IMU odometry with sensor dropout tolerance
Sandipan Das, Navid Mahabadi, Maurice Fallon +1
We present a robust system for state estimation that fuses measurements from multiple lidars and inertial sensors with GNSS data. To initiate the method, we use the prior GNSS pose…
Neural Greedy Pursuit for Feature Selection
Sandipan Das, Alireza M. Javid, Prakash Borpatra Gohain +2
We propose a greedy algorithm to select important features among input features for a non-linear prediction problem. The features are selected one by one sequentially, in a…
Extrinsic Calibration and Verification of Multiple Non-overlapping Field of View Lidar Sensors
Sandipan Das, Navid Mahabadi, Addi Djikic +3
We demonstrate a multi-lidar calibration framework for large mobile platforms that jointly calibrate the extrinsic parameters of non-overlapping Field-of-View (FoV) lidar sensors,…
