Covariance, one of the most widely accepted mathematical tool for similarity measurement relies heavily on the assumption of Gaussian distribution noise model. Along with many other second-order statistics based methods, its performance deteriorates significantly in the presence of impulsive noise. Therefore, in this study, a generalised covariance function named bounded non-linear covariance (BNC)...
A large class of physical phenomenon observed in practice exhibits impulsive, which can be modeled as alpha-stable distribution. Although methods based on fractional lower-order moments (FLOMs) have proven successful in dealing with non-Gaussian impulsive processes, they require in general the previous knowledge or estimation of characteristic exponent in order to choose an appropriate parameter value...
Multiple-access interference (MAI) is concerned widely as one of the most important problems in CDMA system. Most existing researches are under the Gaussian noise assumption, which is not coincident with the real situation. Actually, the more impulsive is the noise, the more severe is the performance degradation incurred by the conventional detectors. This paper proposes a novel robust blind multiuser...
