Summary: | Coalition game theory is introduced to investigate the performance, fairness and stability of decorrelating group multiuser detection receiver, not only from the perspective of individual nodes, but also various coalitions and the whole system as well. Firstly, to derive how the system scale with coa- lition size, a stochastic model with transferable payoffs (stochastic TU-model) is provided. Secondly, to find the most preferred coalition structures from the view point of individual nodes, a model with Non-Transferable payoffs (NTU-model) is presented. Theoretical analysis and simulation results suggest that stochasticaly the grand coalition is payoff maximizing for the system as a whole, while in- dividual nodes with good-conditioned channels may prefer local "win-win coalitions". |
