Optimal Resource Allocation in MIMO Relay Multiple Access Channel

摘要：

We investigate the MIMO Gaussian relay multiple access channels with two colocated users and a destination.We determine the lower bound and upper bound on the sum capacity under time-division decodeand-forward (DF) mode.A resource allocation scheme is proposed to maximize the lower bounds by using superposition modulation.The simulation results show that the proposed scheme can approach the maximum lower bound on the sum capacity of relay multiple access channels.
