DRM Channel Estimation via OMP Algorithm

Year: 2024

Type: article

Abstract: Digital Radio Mondiale (DRM) standard is the most mature digital broadcasting system standard all over the world. Due to the limited spectrum characteristics of DRM communication systems, pilot-based DRM channel estimation brings great challenges. In this paper, the channel estimation problem is transformed into a sparse recovery problem by leveraging the compressed sensing problem. Subsequently, the orthogonal matching pursuit (OMP) sparse recovery algorithm is employed to obtain accurate estimation performance with a lower pilot overhead. Compared with the traditional least square algorithm, simulation results demonstrate that the OMP-based channel estimation algorithm can obtain accurate estimation results with lower pilots, and improve the spectrum utilization while improving the estimation performance.
