AFDM-Aided Grouped RSMA for High-Mobility Downlink Transmissions

Rate-splitting multiple access (RSMA) has emerged as a flexible downlink framework for managing multiuser interference through common and private message splitting. However, in high-mobility scenarios, Doppler-induced intercarrier interference degrades RSMA-based transmission and motivates integration with a transform-...

Sensing-Compatible AFDM Channel Estimation in Time-Scaled Wideband Doubly-Dispersive Channels

Affine frequency division multiplexing (AFDM) is a promising chirp-based waveform for high-mobility and underwater acoustic communications. However, underwater acoustic channels are inherently wideband and characterized by timescaling effects, where Doppler distortion cannot be accurately modeled as a simple frequency...
