Application of the Main Components Method for GNSS Interference Suppression
In this paper three methods of interferences nulling for GNSS GPS or GLONASS are described. A digital antenna array for compensation of interferences is implied. Two methods are based on the eigenvector decomposition of the correlation matrix of received oscillations. An expansion of the correlation...
