Sensing/Decision-Based Cooperative Relaying Schemes With Multi-Access Transmission: Stability Region And Average Delay Characterization
Mohamed Salman, Amr El-Keyi, Mohammed Nafie +1
We consider a cooperative relaying system which consists of a number of source terminals, one shared relay, and a common destination with multi-packet reception (MPR) capability. I…
On the Degrees of Freedom of SISO X-Channel with Alternating CSIT
Ahmed Wagdy, Amr El-Keyi, Tamer Khattab +1
In this paper, we establish the degrees of freedom (DoF) of the two-user single input single output (SISO) X-channel with alternating channel state information at the transmitters…
The asymmetric DoF Region for the 3-user MxN Interference Channel
Mohamed Khalil, Tamer Khattab, Amr El-Keyi +1
In this paper, the 3-user Gaussian MIMO interference channel is considered. The asymmetric distribution of the DoF, where different users have different number of DoF, is studied.…
Power Control for Maximum Throughput in Spectrum Underlay Cognitive Radio Networks
John Tadrous, Ahmed Sultan, Mohammed Nafie +1
We investigate power allocation for users in a spectrum underlay cognitive network. Our objective is to find a power control scheme that allocates transmit power for both primary a…
