Physical layer abstraction aims to evaluate the instantaneous quality of wireless channel.Researches on physical layer abstraction for MIMO system have demonstrated that,EESM algorithm can accurately evaluate channel quality for MIMO system with MMSE detection.However when it comes to MLD,EESM turns invalid.To the question of EESM algorithm,RBIR based physical layer abstraction was proposed from the view of information theory.Simulation results based on WiMAX II DL system show that,the proposed algorithm has improved the accuracy of physical layer abstraction for MIMO system with MLD greatly.
