Spatial-Code-Domain Grouped Index Modulation: Fluid-Antenna-Assisted System Design and BER Performance Analysis
Peng Zhang, Jian Dang, Yao Ge +5
Fluid antenna systems (FASs) provide reconfigurable spatial resources within compact apertures. In this paper, we introduce code-domain grouped index modulation (CGIM) and its spat…
UAV Fluid-Antenna Channel Acquisition under Intra-Scan Channel Aging
Yuanhui Wu, Hao Jiang, Liang Wu +1
Sequential sounding in UAV fluid-antenna systems (FASs) provides additional spatial information but delays transmission, causing earlier channel observations to age. This paper add…
