Design of Non-orthogonal Multiple Access Enhanced Backscatter Communication
Jing Guo, Xiangyun Zhou, Salman Durrani +1
Backscatter communication (BackCom), which allows a backscatter node (BN) to communicate with the reader by modulating and reflecting the incident continuous wave from the reader,…
User Association and Bandwidth Allocation for Terrestrial and Aerial Base Stations with Backhaul Considerations
Elham Kalantari, Irem Bor-Yaliniz, Abbas Yongacoglu +1
Drone base stations (DBSs) can enhance network coverage and area capacity by moving supply towards demand when required. This degree of freedom could be especially useful for futur…
3D Placement of an Unmanned Aerial Vehicle Base Station for Maximum Coverage of Users with Different QoS Requirements
Mohamed Alzenad, Amr El-Keyi, Halim Yanikomeroglu
The need for a rapid-to-deploy solution for providing wireless cellular services can be realized by unmanned aerial vehicle base stations (UAV-BSs). To the best of our knowledge, t…
Enabling Sphere Decoding for SCMA
Monirosharieh Vameghestahbanati, Ebrahim Bedeer, Ian Marsland +2
In this paper, we propose a reduced-complexity optimal modified sphere decoding (MSD) detection scheme for SCMA. As SCMA systems are characterized by a number of resource elements…
Polar Codes for SCMA Systems
Monirosharieh Vameghestahbanati, Ian Marsland, Ramy H. Gohary +1
In this paper, we design and compare multilevel polar coding (MLPC) and bit-interleaved polar coded modulation (BIPCM) for uplink sparse code multiple access (SCMA) systems that op…
Future of Ultra-Dense Networks Beyond 5G: Harnessing Heterogeneous Moving Cells
Sergey Andreev, Vitaly Petrov, Mischa Dohler +1
For the past 40 years, cellular industry has been relying on static radio access deployments with gross over-provisioning. However, to meet the exponentially growing volumes of irr…
