Full-Duplex Transceivers for Next-Generation Wireless Communication Systems
Ian P. Roberts, Himal A. Suraweera
Wireless communication systems can be enhanced at the link level, in medium access, and at the network level when transceivers are equipped with full-duplex capability: the transfo…
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…
Downlink Analysis and Evaluation of Multi-Beam LEO Satellite Communication in Shadowed Rician Channels
Eunsun Kim, Ian P. Roberts, Jeffrey G. Andrews
The extension of wide area wireless connectivity to low-earth orbit (LEO) satellite communication systems demands a fresh look at the effects of in-orbit base stations, sky-to-grou…
LoneSTAR: Analog Beamforming Codebooks for Full-Duplex Millimeter Wave Systems
Ian P. Roberts, Sriram Vishwanath, Jeffrey G. Andrews
This work develops LoneSTAR, a novel enabler of full-duplex millimeter wave (mmWave) communication systems through the design of analog beamforming codebooks. LoneSTAR codebooks de…
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…
