Noncoherent Detection and Interference Nulling for Terrestrial-Satellite Downlink Coexistence in the Upper Mid-Band
Shizhen Jia, C. Nicolas Barati, Marco Mezzavilla +1
Terrestrial--satellite coexistence in the upper mid-band is challenging when a terrestrial base station has limited prior information about non-terrestrial receivers and their upli…
A Self-Calibrating SDR for High Fidelity Beam- and Null-forming Arrays
Yongjun Kim, Aditya Dhananjay, Sundeep Rangan +5
Null forming is increasingly essential in modern wireless systems for spectrum-sharing, anti-jamming, and covert communications in contested and congested environments. Achieving d…
Energy and Latency of Beamforming Architectures for Initial Access in mmWave Wireless Networks
C. Nicolas Barati, Sourjya Dutta, Sundeep Rangan +1
Future millimeter-wave (mmWave) systems, 5G cellular or WiFi, must rely on highly directional links to overcome severe pathloss in these frequency bands. Establishing such links re…
A Case for Digital Beamforming at mmWave
Sourjya Dutta, C. Nicolas Barati, Aditya Dhananjay +3
Due to the heavy reliance of millimeter-wave (mmWave) wireless systems on directional links, beamforming (BF) with high-dimensional arrays is essential for cellular systems in thes…
5G Millimeter Wave Cellular System Capacity with Fully Digital Beamforming
Sourjya Dutta, C. Nicolas Barati, Aditya Dhananjay +1
Due to heavy reliance of millimeter-wave (mmWave) wireless systems on directional links, Beamforming (BF) with high-dimensional arrays is essential for cellular systems in these fr…
