Abstract EN
A compressive sensing based array processing method is proposed to lower the complexity, and computation load of array system and to maintain the robust antijam performance in global navigation satellite system (GNSS) receiver.
Firstly, the spatial and temporal compressed matrices are multiplied with array signal, which results in a small size array system.
Secondly, the 2-dimensional (2D) minimum variance distortionless response (MVDR) beamformer is employed in proposed system to mitigate the narrowband and wideband interference simultaneously.
The iterative process is performed to find optimal spatial and temporal gain vector by MVDR approach, which enhances the steering gain of direction of arrival (DOA) of interest.
Meanwhile, the null gain is set at DOA of interference.
Finally, the simulated navigation signal is generated offline by the graphic user interface tool and employed in the proposed algorithm.
The theoretical analysis results using the proposed algorithm are verified based on simulated results.
