Abstract: We develop a modulation recognition algorithm for orthogonal frequency division multiplexing (OFDM) signals in decode-and-forward (DF) full-duplex (FD) cooperative broadcast systems. In such ...

Abstract: Index modulation (IM) has been proposed and widely demonstrated to improve the spectral efficiency by simultaneously utilizing both the indices of activated subcarriers and their modulated ...

AI-native air interfaces represent a shift from mathematical models to learned representations at the PHY layer.
