Spatial and Statistical Modeling of Multi-Panel Millimeter Wave Self-Interference
Ian P. Roberts, Aditya Chopra, Thomas Novlan +2
Characterizing self-interference is essential to the design and evaluation of in-band full-duplex communication systems. Until now, little has been understood about this coupling i…
STEER: Beam Selection for Full-Duplex Millimeter Wave Communication Systems
Ian P. Roberts, Aditya Chopra, Thomas Novlan +2
Modern millimeter wave (mmWave) communication systems rely on beam alignment to deliver sufficient beamforming gain to close the link between devices. We present a novel beam selec…
Beamformed Self-Interference Measurements at 28 GHz: Spatial Insights and Angular Spread
Ian P. Roberts, Aditya Chopra, Thomas Novlan +2
We present measurements and analysis of self-interference in multi-panel millimeter wave (mmWave) full-duplex communication systems at 28 GHz. In an anechoic chamber, we measure th…
A Real-Time Millimeter Wave V2V Channel Sounder
Aditya Chopra, Andrew Thornburg, Ojas Kanhere +3
Wireless communication in millimeter wave spectrum is poised to provide the latency and bandwidth needed for advanced use cases unfeasible at lower frequencies. Despite the market…
28 GHz Phased Array-Based Self-Interference Measurements for Millimeter Wave Full-Duplex
Aditya Chopra, Ian P. Roberts, Thomas Novlan +1
We present measurements of the 28 GHz self-interference channel for full-duplex sectorized multi-panel millimeter wave (mmWave) systems, such as integrated access and backhaul. We…
A Training-Based Mutual Information Lower Bound for Large-Scale Systems
Xiangbo Meng, Kang Gao, Bertrand M. Hochwald
We provide a mutual information lower bound that can be used to analyze the effect of training in models with unknown parameters. For large-scale systems, we show that this bound c…
Performance Impact Analysis of Beam Switching in Millimeter Wave Vehicular Communications
O. Kanhere, A. Chopra, A. Thornburg +2
Millimeter wave wireless spectrum deployments will allow vehicular communications to share high data rate vehicular sensor data in real-time. The highly directional nature of wirel…
Training-Based Equivalence Relations in Large-Scale Quantized Communication Systems
Kang Gao, Xiangbo Meng, J. Nicholas Laneman +4
We show that a quantized large-scale system with unknown parameters and training signals can be analyzed by examining an equivalent system with known parameters by modifying the si…
Real-time Millimeter Wave Omnidirectional Channel Sounder Using Phased Array Antennas
Aditya Chopra, Andrew Thornburg, Ojas Kanhere +3
Characterization of the millimeter wave wireless channel is needed to facilitate fully connected vehicular communication in the future. To study the multipath-rich, rapidly varying…
