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. Different signal domain such as antenna indexes and constellation symbols is then perceived at each receiver. Consequently, both connectivity and spectral efficiency can be improved by NOMA-QSM. As performance measures, spectral efficiency, connectivity and bit error rate (BER) are evaluated by simulations. The result shows that the proposed NOMA-QSM scheme outperforms the existing schemes.
