Qu Luo, Zilong Liu, Musavian Leila, Thomos Nikolaos, Qihao Peng, Pei Xiao
This paper proposes an Affine frequency division multiplexing (AFDM)-empowered integrated sensing and communications (ISAC) design, referred to as AFDM-ISAC. We first design a novel AFDM-ISAC frame structure that consists of both ISAC and pure data symbols. Each ISAC symbol consi…
