CSNOMA: Carrier Sense Non-Orthogonal Multiple Access [PDF]

open access: yesSensors, 2020
In this paper, we investigate the possibility of the cross-layer design of a distributed random access scheme with considering physical (PHY) and multiple access control (MAC) layers, which utilizes the interference cancellation technique. In this regard,

Rate Compatible Modulation for Non-Orthogonal Multiple Access [PDF]

open access: yesIEEE Access, 2020
We propose a new Non-Orthogonal Multiple Access (NOMA) coding scheme based on the use of a Rate Compatible Modulation (RCM) encoder for each user. By properly designing the encoders and taking advantage of the additive nature of the Multiple Access ...

Non-Orthogonal Multiple Access for Ubiquitous Wireless Sensor Networks [PDF]

open access: yesSensors, 2018
Ubiquitous wireless sensor networks (UWSNs) have become a critical technology for enabling smart cities and other ubiquitous monitoring applications. Their deployment, however, can be seriously hampered by the spectrum available to the sheer number of ...

Noise-Domain Non-Orthogonal Multiple Access

open access: yesIEEE Open Journal of the Communications Society
In this paper, we present noise-domain non-orthogonal multiple access (ND-NOMA), an innovative communication scheme that utilizes the modulation of artificial noise mean and variance to convey information.

Joint power control and user grouping for uplink power domain non-orthogonal multiple access

open access: goldInternational Journal of Distributed Sensor Networks, 2021
Orthogonal multiple access schemes based on assignment of communication resource blocks among multiple contenders, although widely available, still necessitate an upper limit on the number of concurrent users for minimization of multiple-user ...

Non orthogonal multiple access with wind energy harvesting

open access: yesAlexandria Engineering Journal, 2023
In this paper, we derive the performance of wireless communications using wind energy harvesting. We study the single-user and multi-user scenarios using Non Orthogonal and Orthogonal Multiple Access (NOMA and OMA).
