Spatial and Statistical Modeling of Multi-Panel Millimeter Wave Self-Interference

no code implementations14 Oct 2022 Ian P. Roberts, Aditya Chopra, Thomas Novlan, Sriram Vishwanath, Jeffrey G. Andrews

Characterizing self-interference is essential to the design and evaluation of in-band full-duplex communication systems.

STEER: Beam Selection for Full-Duplex Millimeter Wave Communication Systems

no code implementations15 Jul 2022 Ian P. Roberts, Aditya Chopra, Thomas Novlan, Sriram Vishwanath, Jeffrey G. Andrews

Modern millimeter wave (mmWave) communication systems rely on beam alignment to deliver sufficient beamforming gain to close the link between devices.

Beamformed Self-Interference Measurements at 28 GHz: Spatial Insights and Angular Spread

no code implementations15 Jun 2022 Ian P. Roberts, Aditya Chopra, Thomas Novlan, Sriram Vishwanath, Jeffrey G. Andrews

We present measurements and analysis of self-interference in multi-panel millimeter wave (mmWave) full-duplex communication systems at 28 GHz.

28 GHz Phased Array-Based Self-Interference Measurements for Millimeter Wave Full-Duplex

no code implementations5 Mar 2022 Aditya Chopra, Ian P. Roberts, Thomas Novlan, Jeffrey G. Andrews

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.

Training-Based Equivalence Relations in Large-Scale Quantized Communication Systems

no code implementations2 Dec 2020 Kang Gao, J. Nicholas Laneman, Jonathan Chisum, Ralf Bendlin, Aditya Chopra, Bertrand Hochwald

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 signal power and noise variance in a prescribed manner.

FireSim: FPGA-Accelerated Cycle-Exact Scale-Out System Simulation in the Public Cloud

1 code implementation 45th ACM/IEEE International Symposium on Computer Architecture (ISCA 2018) 2018 Sagar Karandikar, Howard Mao, Donggyu Kim, David Biancolin, Alon Amid, Dayeol Lee, Nathan Pemberton, Emmanuel Amaro, Colin Schmidt, Aditya Chopra, Qijing Huang, Kyle Kovacs, Borivoje Nikolic, Randy Katz, Jonathan Bachrach, Krste Asanovic

We present FireSim, an open-source simulation platform that enables cycle-exact microarchitectural simulation of large scale-out clusters by combining FPGA-accelerated simulation of silicon-proven RTL designs with a scalable, distributed network simulation.
