Hierarchical modulation (HM), a promising non-orthogonal multiple access scheme, is able
to provide different levels of protection for data streams and achieve a larger rate region that …

Thanks to the benefits of deploying non-orthogonal multiple access (NOMA) in wireless
communications, ie, wireless sensor networks, we evaluate an energy harvesting wireless …

In this letter, an interference balance power control (IBPC) scheme is proposed for uplink
non-orthogonal multiple access. Compared with fixed signal-to-noise ratio (SNR) difference …
