On power minimization for non-orthogonal multiple access (NOMA)

L Lei, D Yuan, P Värbrand - IEEE Communications Letters, 2016 - ieeexplore.ieee.org
We formulate a power optimization problem for non-orthogonal multiple access systems
mathematically, and prove its NP-hardness. For tackling the problem, we first identify a …
