| Abstract: | A hybrid transmission scheme based on dynamic mode switching between collaborative spatial-multiplexing(CSM) and single-input multi-out(SIMO) was proposed for multi-user multi-antenna uplink CSM systems with imperfect channel state information(CSI).The achievable ergodic rates of CSM and SIMO were analyzed respectively,and the closed-form bounds derived.Performance of the two systems was analyzed,and a mode switching algorithm proposed based on the comparison of the analytical results.Simulation results val... |
