… The cognitive radio network that is under consideration in this work is shown in Fig. 1. It … that
there are n SUs that form the underlay cognitive network with primary user, where n = {1, 2, 3 …

… In this paper, since our main focus is on studying the PR channel capacities, we consider
for simplicity only the interference-power constraint for CR channel capacities. …

… the secondary network physical layer security under the outage constraint of the primary
user (PU) receiver and interference from the PU transmitter to the secondary network. In …

… This paper has investigated the performance of a primary user subject to Poisson distributed
secondary user interferers in a CR underlay system. In contrast to infinite interferers area …

… utilize licensed spectrum in a way that licensed user or primary radio user would not be
interfered. After this approval, Cognitive Radio Networks (CRNs) appear as a promising solution …

… , sensing and Primary User Interference are the bold … interference with Primary Users (PU).
This article presents a novel cognitive radio algorithm called SenPUI for both mentioned main …

… the impact of the cognitive users on the primary users in terms of the interference power, or
… we can control this interference to limit its impact on the primary users’ performance. Assume …

In this paper, we investigate the secrecy performance of a Cooperative Cognitive Radio
Network (CCRN) in the presence of an eavesdropper (EAV). The secondary users (SUs) are …

… modify the air interface of a CR to mimic a primary user signal’s … primary user networks such
as cellular networks [9]. In the paper, we focus on a scenario in which a primary user network …

… (DSA) approach [1], CR users, also designated as secondary users (SUs), are able to … way
