摘要：
This paper formulates the problem of embedded modulation applied to a multiuser multicarrier system. These embedded multiuser optimization problems are shown to be convex, for which globally optimal solutions can be computed efficiently. We also show that these embedded problems are convex relaxations of the combinatorial FDMA multiuser problems and thus provide performance bounds to the optimal and aymptotically optimal solutions proposed in [1] [2].
