This white paper aims to briefly describe a proposed article that willprovide a thorough comparative study of waveforms designed to exploit thefeatures of doubly-dispersive channels arising in heterogeneous high-mobilityscenarios as expected in the beyond fifth generation (B5G) and sixth generation(6G), in relation to their suitability to integrated sensing and communications(ISAC) systems. In particular, the full article will compare thewell-established delay-Doppler domain-based orthognal time frequency space(OTFS) and the recently proposed chirp domain-based affine frequency divisionmultiplexing (AFDM) waveforms. Both these waveforms are designed based on afull delay- Doppler representation of the time variant (TV) multipath channel,yielding not only robustness and orthogonality of information symbols inhigh-mobility scenarios, but also a beneficial implication for environmenttarget detection through the inherent capability of estimating the path delayand Doppler shifts, which are standard radar parameters. These modulationschemes are distinct candidates for ISAC in B5G/6G systems, such that athorough study of their advantages, shortcomings, implications to signalprocessing, and performance of communication and sensing functions are well inorder. In light of the above, a sample of the intended contribution (SpecialIssue paper) is provided below.
