Channel Tracking and Transmission Design in 5G Large-Scale MIMO System

Channel Tracking and Transmission Design in 5G Large-Scale MIMO System

The 5G wireless channel in the high-speed rail scene has the characteristics of fast time-varying and double selection, that is, frequency selectivity and time selectivity. The change in the instantaneous channel parameters is much faster than that in the cellular cell scene, so it is more difficult...
