One of the phenomena that most affects the performance of wireless telecommunications systems is the fading. Thus, several techniques have been proposed to mitigate its effects. These techniques include the so-called opportunistic transmissions, whic

In this paper, the power allocation of Nonorthogonal multiple access (NOMA) for secondary users (SU) in a Cognitive Mobile Radio Network (CMRN) is studied. In the proposed scheme, SUs produce interference to the primary mobile network, which consists

In millimeter-wave (mm-wave) massive MIMO systems, the channel estimation (CE) is a crucial component to set the mm-wave links. Unfortunately, acquiring channel knowledge is a source of training overhead. In this paper, we propose a CE method leverag
