Performances Evaluation and Optimization of Uplink Massive MIMO System

Massive multiple inputs multiple outputs (MIMO) will be the main physical layer technology of 5G systems. Its idea is to use, for each cell, a large number of antennas to increase the network's performances. In order to improve the throughput, 5G system will be aims to use massive MIMO technique in a dense network. In this article, we focus on the study of the uplink massive MIMO system with small cells. The system performances are modeled and optimized. Simulation results show that using massive MIMO with small cells greatly improves the throughput and number of active users in the cellular networks.
