Özet
Accurate signal detection in wireless communication systems is heavily influenced by temporal and spatial channel variations, particularly in the presence of angular spread and Doppler effects. These challenges necessitate advanced signal processing strategies to achieve robust channel estimation. This paper presents an Angular and Doppler Spread Aware Orthogonal Matching Pursuit (OMP) algorithm tailored for Integrated Sensing and Communication (ISAC) systems. By employing basis decomposition in the angular domain and directly modeling Doppler-induced phase variations, the proposed method efficiently estimates channel coefficients while addressing the complexities introduced by channel dynamics. The approach improves the reliability of both sensing and communication functionalities, offering a more seamless integration of these tasks within ISAC frameworks.
