A Fast Broadband Beamspace Transformation
Nakul Singh, Coleman DeLude, Mark Davenport +1
We present a new computationally efficient method for multi-beamforming in the broadband setting. Our "fast beamspace transformation" forms beams from sensor outputs using…
Robust Broadband Beamforming using Bilinear Programming
Nakul Singh, Coleman DeLude, Mark A. Davenport +1
We introduce a new method for robust beamforming, where the goal is to estimate a signal from array samples when there is uncertainty in the angle of arrival. Our method offers sta…
Real-time Digital RF Emulation -- II: A Near Memory Custom Accelerator
Mandovi Mukherjee, Xiangyu Mao, Nael Rahman +16
A near memory hardware accelerator, based on a novel direct path computational model, for real-time emulation of radio frequency systems is demonstrated. Our evaluation of hardware…
Real-time Digital RF Emulation -- I: The Direct Path Computational Model
Coleman DeLude, Joe Driscoll, Mandovi Mukherjee +11
In this paper we consider the problem of developing a computational model for emulating an RF channel. The motivation for this is that an accurate and scalable emulator has the pot…
Subspace Tracking with Dynamical Models on the Grassmannian
Alex Saad-Falcon, Brighton Ancelin, Justin Romberg
Tracking signals in dynamic environments presents difficulties in both analysis and implementation. In this work, we expand on a class of subspace tracking algorithms which utilize…
Confidence-Based Curriculum Learning for Multi-Agent Path Finding
Thomy Phan, Joseph Driscoll, Justin Romberg +1
A wide range of real-world applications can be formulated as Multi-Agent Path Finding (MAPF) problem, where the goal is to find collision-free paths for multiple agents with indivi…
Slepian Beamforming: Broadband Beamforming using Streaming Least Squares
Coleman DeLude, Mark A. Davenport, Justin Romberg
In this paper we revisit the classical problem of estimating a signal as it impinges on a multi-sensor array. We focus on the case where the impinging signal's bandwidth is appreci…
