Communication system commonly exists cochannel interference, which is the main reason why the accuracy of directions-of-arrival (DOAs) estimation is low especially in an alpha stable distribution noise environment. Though the second-order DOA estimation algorithms work well in Gaussian noise, while the methods based on fractional lower-order statistics may do well but which depend on much of apriori...
Fractional Gaussian noise (fGn) with a constant Hurst parameter H can be used to more accurately characterize the long memory process than traditional short-range dependent stochastic processes, such as Markov, Poisson or ARMA processes. However, the ability of fGn is limited for modeling the stochastic processes with prescribed local forms. Therefore, the multifractional Gaussian noise (mGn) with...
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...
