Abstract

The implementation of massive multiple input multiple output systems mMIMO can greatly enhance the spectral efficiency SE performance for users. Although, the cell-edge users as well as indoor users still have a bad performance. The cell-Free network, wherein the large number of existing antennas is replaced by the same number of distributed access points APs, can enlarge the SE performance even for shadowed users. The performance can be further enhanced after application of cooperation. When a Cell-Free mMIMO system is enriched with intelligent reflecting surfaces IRS, its performance may be improved. In this manuscript, the authors will carry out the mathematical model and simulation for the Cell-Free networks employing IRSs. The performance metrics can include the SE as well as energy efficiency EE. From the simulation results, it can be observed that implementation of IRSs inside the cell-Free networks can greatly increase the SE and EE of the system.
