Research on Group Multiuser Detection Coalition Models and Coalition Formation Algorithm
Jun Li · Dianzi xuebao · 2010
In the environment of multiple networks coexisting and sharing spectrum,the issue of group-blind multiuser detection(GBMUD) and GBMUD coalition formation among wireless nodes is addressed under the framework of coalitional game.Firstly,a stochastic multiuser detection model with transferable payoffs(stochastic TU-Model) from system viewpoint is presented;secondly,a model with non-transferable payoffs(NTU-Model) focusing on each MS's preference is introduced;finally,a coalition formation algorithm that maximizes the average users' throughput is derived on the base of the above research results,and is further verified by simulation.
