Abstract: Non-orthogonal multiple access (NOMA) achieved the high throughput by introducing the power domain multiplexing. To improve the spectral efficiency of conventional NOMA scheme, we introduce the spatial domain to NOMA and the proposed scheme is proved has superior performance in spectral efficiency, compared with conventional space shift keying (SSK). The result of simulation confirms that the proposed scheme effectively improve the performance in the aspect of spectral efficiency.
