Multi-Modal Variable-Rate CSI Reconstruction for FDD Massive MIMO Systems
Yunseo Nam, Jiwook Choi
In frequency division duplex (FDD) systems, acquiring channel state information (CSI) at the base station (BS) traditionally relies on limited feedback from mobile terminals (MTs).…

Spatial Lattice Modulation for MIMO Systems
Jiwook Choi, Yunseo Nam, Namyoon Lee
This paper proposes spatial lattice modulation (SLM), a spatial modulation method for multipleinput-multiple-output (MIMO) systems. The key idea of SLM is to jointly exploit spatia…
