Abstract

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 convex problem by relaxation. Based on this convexity, we then propose an efficient 'relax-then-adjust' algorithm and provide results of performance evaluation.
