Pattern Division Multiple Access: A New Multiple Access Technology for 5G

IEEE Wireless Communications, 2018
The anticipated 1000-fold increase in mobile data traffic over the next decade and the explosion of new services and applications pose great challenges for the current orthogonal multiple access (OMA)-based 4G systems. A promising solution to address these challenges is to shift from the currently predominant OMA to non-orthogonal multiple access (NOMA)

Pattern Division Multiple Access—A Novel Nonorthogonal Multiple Access for Fifth-Generation Radio Networks

IEEE Transactions on Vehicular Technology, 2017
In this paper, pattern division multiple access (PDMA), which is a novel nonorthogonal multiple access scheme, is proposed for fifth-generation (5G) radio networks. The PDMA pattern defines the mapping of transmitted data to a resource group that can consist of time, frequency, and spatial resources or any combination of these resources. The pattern is

On the performance of pattern division multiple access in 5G systems

2016 8th International Conference on Wireless Communications & Signal Processing (WCSP), 2016
Pattern division multiple access (PDMA) is one of the important candidate multiple access technologies for future 5G wireless communication systems. It can improve the spectral efficiency and support the massive connection based on the reasonable unequal diversity between users.
