Speech-Synchronized Whiteboard Generation via VLM-Driven Structured Drawing Representations
Suraj Prasad, Pinak Mahapatra
Creating whiteboard-style educational videos demands precise coordination between freehand illustrations and spoken narration, yet no existing method addresses this multimodal sync…
Geolocation with Large LEO Constellations: Insights from Fisher Information
Don-Roberts Emenonye, Harpreet S. Dhillon, R. Michael Buehrer
Interest in the use of the low earth orbit (LEO) in space - from to - has skyrocketed; this is evident by the fact that National Aeronautics and…
Impact of Model Mismatch on DOA Estimation with MUSIC: Near-Field and Far-Field
Don-Roberts Emenonye, Harpreet S. Dhillon, R. Michael Buehrer
There has been substantial work on developing variants of the multiple signal classification (MUSIC) algorithms that take advantage of the information present in the near-field pro…
Fundamentals of LEO Based Localization
Don-Roberts Emenonye, Harpreet S. Dhillon, R. Michael Buehrer
In this paper, we derive the fundamental limits of low earth orbit (LEO) enabled localization by analyzing the available information in signals from multiple LEOs during different…
Differential Deep Detection in Massive MIMO With One-Bit ADC
Don-Roberts Emenonye, Carl Dietrich, R. Michael Buehrer
This article presents a differential detection scheme for the uplink of a massive MIMO system that employs one-bit quantizers on each receive antenna. We focus on the detection of…
