Adaptive Cell Range Expansion in Multi-Band UAV Communication Networks
Xinsong Feng, Ian P. Roberts
This paper leverages stochastic geometry to model, analyze, and optimize multi-band unmanned aerial vehicle (UAV) communication networks operating across low-frequency and millimet…
Analog Beamforming Codebooks for Wideband Full-Duplex Millimeter-Wave Systems
Sungho Cho, Ian P. Roberts
In full-duplex millimeter-wave (mmWave) systems, the effects of beam squint and the frequency-selectivity of self-interference exacerbate over wide bandwidths. This complicates the…
Splitting Messages in the Dark- Rate-Splitting Multiple Access for FDD Massive MIMO Without CSI Feedback
Namhyun Kim, Ian P. Roberts, Jeonghun Park
A critical hindrance in realizing frequency division duplex (FDD) massive multi-input multi-output (MIMO) systems is the overhead associated with the downlink (DL) channel state in…
Analog Beamforming for In-Band Full-Duplex Phased Arrays with Quantized Phase Shifters under a Per-Antenna Received Power Constraint
Ao Liu, Ian P. Roberts, Taneli Riihonen +1
This letter develops a novel transmit beamforming (BF) design for canceling self-interference (SI) in analog in-band full-duplex phased arrays. Our design maximizes transmit BF gai…
