Abstract
Safety-critical applications (SCA), such as civil aviation and autonomous driving, and liability critical applications (LCA), such as precision agriculture, require a robust positioning system in demanding signal environments with coherent multipath while ensuring reasonably low complexity. In this context, antenna array based Global Navigation Satellite Systems (GNSS) receivers with array signal processing schemes allow the spatial separation of line-of-sight (LOS) from multipath components. In this paper, we propose a three step tensor-based approach applying direction of arrival (DoA) estimation and Khatri-Rao factorization (KRF) to separate the code for each impinging component. Our scheme outperforms the Higher-Order Singular Value Decomposition (HOSVD) based eigenfilter, which is the state-of-the-art tensor based scheme for delay estimation.
