Interleaver-Based Pattern Division Multiple Access with Iterative Decoding and Detection

2017 IEEE 85th Vehicular Technology Conference (VTC Spring), 2017
Pattern Division Multiple Access (PDMA) is a novel non-orthogonal multiple access scheme proposed to meet the demand of massive connection in the future 5G communications. PDMA is based on the joint design of transmitter and receiver. The multiuser signals are superposed on the multiple signal domains based on different characteristic patterns at the ...

Double-weight signature pattern codes for multicore-fiber code-division multiple-access networks

IEEE Communications Letters, 2001
To transmit digitized image pixels in optical code-division multiple-access (CDMA) networks with multicore fiber, classes of two-dimensional (2-D) patterns, so-called optical orthogonal signature pattern codes (OOSPCs), have previously been proposed.

Demonstration of Pattern Division Multiple Access With Message Passing Algorithm for Multi-Channel mmWave Uplinks via RoF Mobile Fronthaul

Journal of Lightwave Technology, 2020
Orthogonal multiple access (OMA) such as orthogonal frequency division multiple access (OFDMA) has been the predominant access technology adopted by the current generation of mobile communication. Representing an evolutionary step in radio access networks, non-orthogonal multiple access (NOMA) is considered to be a promising technology to meet the ...

A Pattern Division Multiple Access Scheme with Low Complexity Iterative Receiver for 5G Wireless Communication Systems

2018 IEEE 88th Vehicular Technology Conference (VTC-Fall), 2018
Non-orthogonal multiple access schemes with higher spectral efficiency and the capability of accessing more users than orthogonal multiple access (OMA) scheme is preferred for the fifth generation (5G) wireless networks. In this work, a non-orthogonal transmission scheme called pattern division multiple access (PDMA) is proposed for the 5G wireless ...
