Hybrid Analog-Digital Beamforming for Massive MIMO Systems
Shahar Stein Ioushua, Yonina C. Eldar
In massive MIMO systems, hybrid beamforming is an essential technique for exploiting the potential array gain without using a dedicated RF chain for each antenna. In this work, we…
High Resolution FDMA MIMO Radar
David Cohen, Deborah Cohen, Yonina C. Eldar
Traditional multiple input multiple output radars, which transmit orthogonal coded waveforms, suffer from range-azimuth resolution trade-off. In this work, we adopt a frequency div…
Fourier Phase Retrieval: Uniqueness and Algorithms
Tamir Bendory, Robert Beinert, Yonina C. Eldar
The problem of recovering a signal from its phaseless Fourier transform measurements, called Fourier phase retrieval, arises in many applications in engineering and science. Fourie…
Online Dictionary Learning Aided Target Recognition In Cognitive GPR
Fabio Giovanneschi, Kumar Vijay Mishra, Maria Antonia Gonzalez-Huici +2
Sparse decomposition of ground penetration radar (GPR) signals facilitates the use of compressed sensing techniques for faster data acquisition and enhanced feature extraction for…
