IEEE Transactions on Aerospace and Electronic Systems. ISSN 0018-9251. Vol. 52, N.º 5 (2016), pp. 2574–25860018-9251http://hdl.handle.net/10400.21/7946GNSS signals affected by additive channel noise are approximately Gaussian, but often the presence of interference may change that distribution.We propose a blind detection method based on the Giannakis-Tsatsanis Gaussianity test to evaluate the presence of narrowband and wideband non-Gaussian interference. This method, resorting to the sample fourth-order autocumulants, is compared to other Gaussianity tests. The asymptotic covariance matrix of the estimated autocumulant vector is analytically determined, thus reducing the complexity of the proposed technique.engSignalTestsOrderjournal article10.1109/TAES.2016.150499
