Massive MIMO Channel Modeling Based On Image Method

Massive MIMO wireless communication technology is becoming more and more mature and actively promotes the development of 5G.Massive MIMO technology breakthrough is the ability to completely coherent adapt to the use of a number of services for antenna,without any increase in signal transmission bandwidth and send power under the premise of the frequency spectrum efficiency and power efficiency have been improved significantly.In order to better study the channel propagation characteristics of Massive MIMO,we need to conduct channel modeling to get more comprehensive research channel characteristics.This paper analysis and simulation for the channel modeling,first of all,through the analysis of the various models of comparative channel modeling,adopt a deterministic model to Massive MIMO indoor modeling?Then having a measurement in a meeting,through the time delay measurement and simulation of the power spectrum and delay spread,and verify the correctness of the channel model and availability.The main achievements and innovations include the following aspects:(1)Based on the modeling of the scene specific geometry information as well as the surface material relative dielectric constant and magnetic permeability,using image method for Massive MIMO simple indoor environment simulation,analysis the parameters to get the Massive MIMO features.(2)Design is the maximum number of 128 linear array antenna array,the actual measurement carried out on a hall.(3)The actual measurement results are compared with the simulation results,it is concluded that the applicability of the channel model.It provides strong theoretical support for exploring the propagation characteristics of Massive MIMO channel.
