Game theoretic power allocation for fading MIMO multiple access channels with imperfect CSIR

摘要: In this paper, we formulate the power allocation (PA) problem for uplink of MIMO fading multiple access channels using a game theoretic framework with channel estimation error at receiver side. We investigate effect on derived PA policy and performance system. Furthermore, it is assumed that CSI transmitter side imperfect i.e., each informed statistics instead instantaneous states. use lower bound mutual information between user base station to derive utility function concave game, regarding error. Following formulation problem, existence uniqueness game's equilibrium are investigated proved proposed has unique Nash (NE). Also primal-dual subgradient based best-response algorithm designed find NE. The updates player given other players, iteration. Finally, simulation results achieved illustrated particular, simulations show overall system will be improved when in modeling considered.
