Blind Adaptive Beamformer Based on Orthogonal Projections for GNSS
, 2012 The quality of the ranging data provided by a global navigation satellite systems (GNSS) receiver largely depends on the synchronization error, that is, on the accuracy of the propagation time-delay estimation of the line-of-sight (LOS) signal.
