Simulation of Beamforming by Massive MIMO Antennas

Featured Product from Remcom (USA)

This paper, presented at EDI CON 2016, demonstrates a new predictive capability for simulating massive MIMO antennas and beamforming in dense urban propagation environments.

In anticipation of rapid growth in wireless device and mobile data demand, multiple input multiple output (MIMO) is one of the key technologies being researched for 5G; however, traditional methods for channel modeling present shortfalls, either in their ability to model the details required for MIMO systems, or in the level of computation that they must perform to handle the increasing numbers of antennas and channels.

To overcome these shortfalls, Remcom has developed an innovative and optimized approach for efficiently simulating the detailed multipath of large numbers of MIMO channels using ray-tracing, while overcoming the limitations and computational complexity of traditional ray-tracing methods.  Wireless InSite® MIMO is used to predict the complex channel matrix for mobile devices within a small cell.  We then apply beamforming techniques to predict and display the actual physical beams to each device and evaluate signal power and interference, including the impacts when pilot contamination is present.
