Effective Capacity of Cognitive Radio Links: Accessing Primary Feedback Erroneously
M. Majid Butt, Ahmed Anwar, Amr Mohamed +1
We study the performance of a cognitive system modeled by one secondary and one primary link and operating under statistical quality of service (QoS) delay constraints. We analyze…
Interference-Based Optimal Power-Efficient Access Scheme for Cognitive Radio Networks
Ahmed H. Anwar, Ahmed El Shafie, Amr Mohamed +2
In this paper, we propose a new optimization-based access strategy of multipacket reception (MPR) channel for multiple secondary users (SUs) accessing the primary user (PU) spectru…
Effective Capacity of Delay Constrained Cognitive Radio Links Exploiting Primary Feedback
Ahmed H. Anwar, Karim G. Seddik, Tamer ElBatt +1
In this paper, we analyze the performance of a secondary link in a cognitive radio (CR) system operating under statistical quality of service (QoS) delay constraints. In particular…
