AFDM-Enabled Spatial Modulation for A-RoF Optical Fronthaul Networks
Fiber-wireless integrated networks are emerging as a key enabler for next-generation high-capacity access, where centralized architectures demand both efficient signal transmission and low-complexity remote units. This paper presents an AFDM-enabled analogue radio-over-fiber (A-RoF) aided spatial modulation (SM) archit...
