Joint Interference Estimation and Detection in Uplink of Massive MIMO System

Abstract

In this article, the joint detection in uplink are studied in Massive MIMO (Massive Multiple-input Multiple-output) system. This article will combine several precoding techniques such as ZF (Zero Force), MMSE (Minimum Mean Square Error), BD (Block Diagonalization) in interference estimation and propose a new structure for joint detection in uplink based on 5G simulation test platform of NCRL (National Mobile Communications Research Laboratory of SEU). Finally, this article will analysis feasibility of the new structure and give out simulation results.
