A Pricing-Based Cooperative Spectrum Sharing Stackelberg Game
Ramy E. Ali, Karim G. Seddik, Mohammed Nafie +1
We consider the problem of cooperative spectrum sharing among a primary user (PU) and multiple secondary users (SUs) under quality of service (QoS) constraints. The SUs network is…
Generalized Instantly Decodable Network Coding for Relay-Assisted Networks
Adel M. Elmahdy, Sameh Sorour, Karim G. Seddik
In this paper, we investigate the problem of minimizing the frame completion delay for Instantly Decodable Network Coding (IDNC) in relay-assisted wireless multicast networks. We f…
Pseudo-Lattice Treatment for Subspace Aligned Interference Signals
Yahya H. Ezzeldin, Karim G. Seddik
For multi-input multi-output (MIMO) K-user interference networks, we propose the use of a channel transformation technique for joint detection of the useful and interference signal…
Sparse Reconstruction-based Detection of Spatial Dimension Holes in Cognitive Radio Networks
Yahya H. Ezzeldin, Radwa A. Sultan, Karim G. Seddik
In this paper, we investigate a spectrum sensing algorithm for detecting spatial dimension holes in Multiple Inputs Multiple Outputs (MIMO) transmissions for OFDM systems using Com…
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…
