报告摘要：

Integrated sensing and communication (ISAC) is emerging as a promising technology for next-generation wireless networks by allowing radar sensing and wireless communication to share hardware and spectrum resources. A common ISAC strategy is to perform sensing based on the communication signal frame, which typically consists of a predefined preamble sequence followed by a time-varying information-carrying data payload. However, existing communication frames are not primarily designed for radar sensing, and their ambiguity-function (AF) sidelobes may degrade target detection and delay–Doppler estimation performance. This talk presents our recent work on improving ISAC sensing performance from three complementary perspectives. The first two perspectives focus on improving sensing while largely preserving the communication frame structure or communication performance, through preamble-sequence design and sensor-side delay–Doppler processing. The third perspective considers new waveform design for future ISAC systems, where sensing and communication performance can be balanced more flexibly through explicit trade-offs.
