MARS: Message Passing for Antenna and RF Chain Selection for Hybrid Beamforming in MIMO Communication Systems
Li-Hsiang Shen, Yen-Chun Lo, Kai-Ten Feng +2
In this paper, we consider a prospective receiving hybrid beamforming structure consisting of several radio frequency (RF) chains and abundant antenna elements in multi-input multi…
Spectral-Efficiency of Cell-Free Massive MIMO with Multicarrier-Division Duplex
Bohan Li, Lie-Liang Yang, Robert G. Maunder +2
A multicarrier-division duplex (MDD)-based cell-free (CF) scheme, namely MDD-CF, is proposed, which enables downlink (DL) data and uplink (UL) data or pilots to be concurrently tra…
Multicarrier-Division Duplex for Solving the Channel Aging Problem in Massive MIMO Systems
Bohan Li, Lie-Liang Yang, Robert G Maunder +2
The separation of training and data transmission as well as the frequent uplink/downlink (UL/DL) switching make time-division duplex (TDD)-based massive multiple-input multiple-out…
Heterogeneous graph neural network for power allocation in multicarrier-division duplex cell-free massive MIMO systems
Bohan Li, Lie-Liang Yang, Robert G Maunder +2
In-band full duplex cell-free (CF) systems suffer from severe self-interference and cross-link interference, especially when CF systems are operated in distributed way. To this end…
