title = "Unique Word-Based Frame Design for Bistatic ISAC with Time-Domain Filtering",
abstract = "Integrated sensing and communication (ISAC) aims at enhancing the network functionalities and enabling new applications in the upcoming communications networks. In this paper, we propose two unique word (UW)-based frame designs for bistatic ISAC. The approach consists of replacing the cyclic prefix (CP) with a Zadoff-Chu (ZC)-based sequence. With this approach, the radar receiver does not need to know the data symbols to perform sensing and the data rate is not compromised by the addition of extra pilots. We derive the Cram{\'e}r-Rao bound (CRB) considering a band-limited system with raised-cosine filtering. Furthermore, we evaluate the performance of a low-complexity fast Fourier transform (FFT)-based radar receiver that performs integer and fine grid delay-Doppler (DD) estimation, using the CRB as a benchmark.",
