Joint Optimization of Integrated Sensing and Communications in Precoded Multi-Carrier Faster-Than-Nyquist Signaling

In this paper, we propose a precoded faster-than-Nyquist (FTN) dual-functional integrated sensing and communication (ISAC) waveform, which improves the information rate of the conventional orthogonal multi-carrier architecture.
