A Deep Reinforcement Learning Framework for Data Compression in Uplink NOMA-SWIPT Systems
( Institute of Electrical and Electronics Engineers Inc. , 2021 , Article)<comment< Non-orthogonal multiple access (NOMA) shall play an important role in the current and foreseeable design of 5G and beyond networks. NOMA allows multiple users to share the same time-frequency ... -
A Novel Downlink IM-NOMA Scheme
( Institute of Electrical and Electronics Engineers Inc. , 2021 , Article)In the next generations of communication systems, resources' scarcity devolves to a more critical point as a consequence of the expected massive number of users to be served. Furthermore, the users' contradicting requirements ... -
Generalized dynamic spectrum access: An order statistics design perspective
( Elsevier GmbH , 2008 , Article)A new adaptive multiple access scheme based on the theory of order statistics is introduced. The proposed algorithm employs a semi-random allocation mechanism that limits subchannel selection to the highest-gain subchannels. ... -
Performance Analysis of PLS key generation-based Secure NOMA-enabled IoT Networks in the presence of Untrusted Users
( Institute of Electrical and Electronics Engineers Inc. , 2021 , Conference Paper)In Internet of Things (IoT), a massive amount of sensitive data is generated and transmitted by IoT devices. Security risks represent a major concern in IoT, especially when using innovative techniques such as Non-Orthogonal ... -
Secrecy Performance Analysis of Cooperative NOMA system with multiple DF Relays
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Conference Paper)In this paper, we derive the Secrecy Outage Probability (SOP) and Strictly Positive Secrecy Capacity (SPSC) of cooperative Non Orthogonal Multiple Access (NOMA) in the presence of K Decode and Forward (DF) relays and ... -
Secrecy performance analysis of half/full duplex AF/DF relaying in NOMA systems over κ−μ fading channels
( Springer , 2022 , Article)Although the progress in understanding 5G and beyond techniques such as Non-Orthogonal Multiple Access (NOMA) and full-duplex techniques has been overwhelming, still analyzing the security aspects of such systems under ... -
Secrecy Performance Analysis of Multi-Antenna NOMA System with AF/DF relaying under External and Internal Eavesdropping Scenarios
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Conference Paper)Due to the successive interference cancellation (SIC) technique, Non orthogonal multiple Access (NOMA) users have the capability of decoding the other paired users sharing the same resource bloc. As a result, NOMA technique ... -
Secure Performance of DF Relaying in Cooperative NOMA over Rician Fading Channels
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Conference Paper)In this paper, a Decode-and-Forward (DF) relaying system for Non Orthogonal Multiple Access (NOMA) networks is considered, where the transmitted information between the relay and NOMA users can be overheard by an eavesdropper. ...
