In this paper, multi-user multiple-input multiple output (MU-MIMO) transmission in long term evolution (LTE)-Advanced system is presented. To support dynamic scheduling of MIMO transmission, enhanced node B (eNB) does not inform user equipment (UE) of the existence of other co-scheduled UE. In this case, the UE cannot perform any interference mitigation scheme because it does not know whether the...
In this paper, we propose an enhanced channel estimation method for multi-user multiple-input multiple output (MU-MIMO) based long term evolution (LTE)-Advanced system. In MU-MIMO based LTE-Advanced system, the orthogonality between co-scheduled layers is not perfectly guaranteed. In this case, significant performance degradation in channel estimation can occur due to the interference from transmit...
