On The Construction of Capacity-Achieving Lattice Gaussian Codes
Wael Alghamdi, Walid Abediseid, Mohamed-Slim Alouini
In this paper, we propose a new approach to proving results regarding channel coding schemes based on construction-A lattices for the Additive White Gaussian Noise (AWGN) channel t…
Underlay Spectrum Sharing Techniques with In-band Full-Duplex Systems using Improper Gaussian Signaling
Mohamed Gaafar, Osama Amin, Walid Abediseid +1
Sharing the spectrum with in-band full-duplex (FD) primary users (PU) is a challenging and interesting problem in the underlay cognitive radio (CR) systems. The self-interference i…

Mohamed Gaafar, Osama Amin, Walid Abediseid +1
Sharing the spectrum with in-band full-duplex (FD) primary users (PU) is a challenging and interesting problem in the underlay cognitive radio (CR) systems. The self-interference i…
Spectrum Sharing Opportunities of Full-Duplex Systems using Improper Gaussian Signaling
Mohamed Gaafar, Osama Amin, Walid Abediseid +1
Sharing the licensed spectrum of full-duplex (FD) primary users (PU) brings strict limitations on the underlay cognitive radio operation. Particularly, the self interference may ov…
On Lattice Sequential Decoding for The Unconstrained AWGN Channel
Walid Abediseid, Mohamed-Slim Alouini
In this paper, the performance limits and the computational complexity of the lattice sequential decoder are analyzed for the unconstrained additive white Gaussian noise channel. T…
On the Average Complexity of Sphere Decoding in Lattice Space-Time Coded MIMO Channel
Walid Abediseid
The exact average complexity analysis of the basic sphere decoder for general space-time codes applied to multiple-input multiple-output (MIMO) wireless channel is known to be diff…
