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…
Iterative Broadband Source Localization
Coleman DeLude, Rakshith Sharma, Santhosh Karnik +3
In this paper we consider the problem of localizing a set of broadband sources from a finite window of measurements. In the case of narrowband sources this can be reduced to the pr…
