Homomorphic Directional Beamforming with Analog True Time Delay Arrays
Ibrahim Pehlivan, Danijela Cabric
Recently, true-time-delay (TTD) arrays, also referred to as joint phase-time arrays (JPTA), have been investigated for low-cost frequency-dependent beamforming capabilities to enab…
The Radon Transform, True Time Delay Beamforming, and Ultra-Wideband Antenna Arrays (Invited Paper)
Tyler Ikehara, Ibrahim Pehlivan, Danijela Cabric +1
The FR3 band has emerged as the major focus of 6G wireless research. FR3 cellular operation presents the challenge of extreme bandwidth combined with physically large antenna array…
Sparse Bayesian Learning Algorithms Revisited: From Learning Majorizers to Structured Algorithmic Learning using Neural Networks
Rushabha Balaji, Kuan-Lin Chen, Danijela Cabric +1
Sparse Bayesian Learning is one of the most popular sparse signal recovery methods, and various algorithms exist under the SBL paradigm. However, given a performance metric and a s…
Millimeter-Wave True-Time Delay Array Beamforming with Robustness to Mobility
Benjamin W. Domae, Ibrahim Pehlivan, Danijela Cabric
