DOI: 10.1109/access.2017.2687078
Abstract: In order to meet the ever increasing data rate demands, the next generation of wireless communication systems is being designed for exploiting the large amounts of unused spectrum in the millimeter-wave (mm-wave) band. Since operating… read more here.

DOI: 10.21595/jve.2017.18039
Abstract: This article addresses the problem of blind source separation, in which the source signals are most often of the convolutive mixtures, and moreover, the source signals cannot satisfy independent identical distribution generally. One kind of… read more here.
