Abstract

This paper investigates the joint power and admission control problem for a multi-pair massive multiple-input multiple-output (MIMO) amplify-and-forward relaying system. Our aim is to minimize the total transmit power for users while maximizing the number of supported users by adopting the new linear programming deflation (NLPD) algorithm. Here, the removal strategy of the NLPD algorithm is compared with the deflation based joint user removal and power allocation (DPA) algorithm and the effect of the number of relay's antennas is also analyzed for this system. Monte-Carlo simulation results indicate that with thorough removal strategy, the NLPD algorithm can support more users than that of the DPA algorithm with almost equal average transmit powers allocated for each user-pair. In addition, although both of the algorithms can accommodate all user-pairs when the number of antennas is sufficiently large, while the computational complexity of the NLPD algorithm is at least one order of magnitude lower than that of the DPA algorithm.
