Optimal Spectrum Access for a Rechargeable Cognitive Radio User Based on Energy Buffer State
Ahmed El Shafie, Mahmoud Ashour, Amr Mohamed +1
This paper investigates the maximum throughput for a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU) plugged to a reliable power supply. The SU maint…
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…
On Spectrum Sharing Between Energy Harvesting Cognitive Radio Users and Primary Users
Ahmed El Shafie, Mahmoud Ashour, Tamer Khattab +1
This paper investigates the maximum secondary throughput for a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU) plugged to a reliable power supply. Th…
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.…
Stationarity of Stochastic Processes In The Fractional Fourier Domains
Ahmed El Shafie, Tamer Khattab
In this paper, we investigate the stationarity of stochastic processes in the fractional Fourier domains. We study the stationarity of a stochastic process after performing fractio…
