QSM based NOMA for Multi-User Wireless Communication [PDF]
2019 16th International Symposium on Wireless Communication Systems (ISWCS), 2019 In this study, a quadrature spatial modulation (QSM) based non-orthogonal multiple access (NOMA) for multiuser, named as NOMA-QSM, is proposed. The main idea of NOMA-QSM is to superimpose several constellation symbols to be transmitted simultaneously via some selected antenna indexes by distinguishing power domain.

Realistic in silico abdominal QSM phantom
ISMRM Annual Meeting, 2023 Compared to Quantitative Susceptibility Mapping (QSM) in the brain, abdominal QSM faces additional issues due to the presence of gas and fatty tissue. Recent works in abdominal QSM are more focused on its feasibility as a biomarker for disease diagnosis than improving or assessing the robustness and quality of the reconstructions.

Towards energy-efficient modulation: PIM-QSM and EPIM-QSM schemes
Physical CommunicationThe sixth-generation (6G) network is anticipated to meet energy efficiency (EE) standards while enabling data transmission speeds much faster than current networks. Quadrature spatial modulation (QSM) can effectively meet the requirements of EE. Meanwhile, pulse index modulation (PIM) is another innovative scheme that satisfies the EE demands of ...
