Design of PDMA Pattern Matrix in 5G Scenarios

2020 IEEE 91st Vehicular Technology Conference (VTC2020-Spring), 2020
Pattern division multiple access (PDMA) is a novel non-orthogonal multiple access (NOMA) solution to the problem of massive connection and higher spectral efficiency for the fifth generation (5G) wireless networks. The performance of PDMA is determined by the gain brought by the PDMA pattern and is generally related to the inner product of the pattern.

A novel power allocation strategy for cooperative PDMA systems

Physical Communication, 2022
Cooperative communication technology is of great importance for increasing the user reachable rate, further improving throughput and reducing the outage probability of non-orthogonal multiple access (NOMA) systems. This paper mainly studies the power allocation optimization method based on amplify-and-forward (AF) pattern division multiple access (PDMA)
