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…
