We analyse a cell of Cognitive Radio Network ( $CRN$ ) as the multiline queueing system supplying service to two Markovian arrival flows of users. Primary (or licensed) users called as High Priority Users ( $HPU\text{s}$ ) have a preemptive priority

This paper presents a simplified joint synchronization scheme for the integer carrier frequency offset and physical cell identity using a primary synchronization signal (PSS) in 5G new radio (NR) communication systems. We demonstrate the efficiency o

The implementation of a geographic exclusion zone (GEZ) has been a scheme in regulations developed to protect a primary user (PU) in dynamic spectrum access wireless networks, where secondary users (SUs) can transmit only outside the exclusion zone r

Introduction. One of the classes of modern radio engineering systems are systems with spatial diversity of transmitting, receiving or transceiving elements. In such systems, an increase of the information content is achieved by signal coprocessing en

Cognitive radio (CR) networks allow secondary users (SUs) to access and use the spectrum opportunistically. However, some misbehavior users mislead SUs to evacuate the spectrum by launching a primary user emulation attack (PUEA), which is a denial of
