Abstract EN
Interference suppression techniques have been intensively studied in nearly two decades due to their importance for maintaining the integrity and functionality of global navigation satellite system (GNSS).
However, the interference suppression method applicable for the complex receiving environment in which there are multitype interfering signals has not been considered in most of the researches.
To deal with this problem better, a cascaded multitype interferences suppression method using sparse representation and array processing is proposed.
In the first stage, according to the sparsity of the narrowband and modulated wideband interference signals, a novel parallel multichannel signal interference suppression method based on matching pursuit (MP) algorithm and a design strategy for the overcomplete dictionary are proposed to mitigate the interferences with sparse features.
Then, the minimum power distortionless response (MPDR) beamformer is employed in the second stage to suppress the residuary interferences (such as Gaussian noise interferences).
Compared with existing algorithms, the proposed method can not only effectively suppress the interference arriving from the same direction with the desired signal and increase the Degree of Freedom (DoF) of the array antenna, but also introduce no distortion into the navigation signal.
The effectiveness of the proposed method is illustrated by theoretical analysis and several simulation results.
