Waveform Design of Integrated Communication and Navigation System in High Dynamic Scenarios

High-dynamic scenarios pose significant challenges to the stability and performance of integrated communication and navigation (ICAN) systems. To address this issue, this paper proposes a frame structure for an anti-high-dynamic ICAN system, enabling high-precision navigation and reliable communication even under high-speed motion and complex Doppler shifts. A preamble sequence is designed for coarse frequency offset estimation, while pilot sequences are utilized for fine frequency offset estimation. This approach effectively mitigates the impact of Doppler frequency offsets on the ICAN system, providing both a theoretical foundation and technical support for the application of ICAN technology in complex scenarios. Simulation results validate the effectiveness and robustness of the proposed frame structure.
