Non-Orthogonal Multiple Access for Vehicular Communication [PDF]
2018 15th International Symposium on Wireless Communication Systems (ISWCS), 2018 In this paper, we establish a simple model for the exchange of messages in a vehicular network and we consider fundamental limits on the achievable data rate. For a vehicular network, the exchange of data with other nearby vehicles is particularly important for traffic safety, e.g.

A Unified Framework for Non-Orthogonal Multiple Access [PDF]
IEEE Transactions on Communications, 2018 This paper proposes a unified framework of non-orthogonal multiple access (NOMA) networks. Stochastic geometry is employed to model the locations of spatially NOMA users. The proposed unified NOMA framework is capable of being applied to both code-domain NOMA (CD-NOMA) and power-domain NOMA (PD-NOMA).
