We analyze the sensitivity of a proposed blind detection method based on the Giannakis-Tsatsanis Gaussianity test to evaluate the presence of narrowband and wideband non-Gaussian interference. Robustness of the proposed method to the blind-spot effect that occurs in pulsed interference signals is also discussed.engGiannakis-Tsatsanis testGaussianity testsInterference detectionAutocumulantsGNSS receiversBlind-spot effectconference object10.1109/ICL-GNSS.2016.7533690
