Due to the increasing demand for fast data rates and large spectra, millimeter-wave
technology plays a vital role in the advancement of 5G communication. The idea behind Mm …

Cognitive radio (CR) is a wireless technology for increasing the bandwidth usage. Spectrum
sensing (SS) is the first step in CR. There are three basic techniques in SS, energy detection …

In this paper, we discussed the parametric optimization of improved sensing schemes in
multi-antenna cognitive radio (CR) networks over an erroneous channel. The CR utilizes an …

In cognitive radio technology, spectrum sensing is essential for detecting spectrum holes
which may be allotted to secondary users. In this paper, an optimal voting rule is used for …

Spectrum sensing is a cognitive radio technique which distributes the unused spectrum hole
of primary users (PU) to secondary users (SU). This technique can remarkably improve the …

Abstract—The Bartlett's periodogram is widely used in the spectrum sensing applications
since it does not need any preknown information about the primary user signal. However, it …

Different priorities of users' access are defined in cognitive radio networks (CRNs) in order to
differentiate the spectrum usage: primary user (PU) preferentially occupies the band …
