Optimal Water-Filling Algorithm in Downlink Multi-Cluster NOMA Systems
Sepehr Rezvani, Eduard A. Jorswieck
The key idea of power-domain non-orthogonal multiple access (NOMA) is to exploit the superposition coding (SC) combined with successive interference cancellation (SIC) technique (c…
Optimal SIC Ordering and Power Allocation in Downlink Multi-Cell NOMA Systems
Sepehr Rezvani, Eduard A. Jorswieck, Nader Mokari +1
In this work, we propose a globally optimal joint successive interference cancellation (SIC) ordering and power allocation (JSPA) algorithm for the sum-rate maximization problem in…
Resource Allocation in Virtualized CoMP-NOMA HetNets: Multi-Connectivity for Joint Transmission
Sepehr Rezvani, Nader Mokari, Mohammad R. Javan +1
In this work, we design a generalized joint transmission coordinated multi-point (JT-CoMP)-non-orthogonal multiple access (NOMA) model for a virtualized multi-infrastructure networ…
Cooperative Multi-Bitrate Video Caching and Transcoding in Multicarrier NOMA-Assisted Heterogeneous Virtualized MEC Networks
Sepehr Rezvani, Saeedeh Parsaeefard, Nader Mokari +2
Cooperative video caching and transcoding in mobile edge computing (MEC) networks is a new paradigm for future wireless networks, e.g., 5G and 5G beyond, to reduce scarce and expen…
