摘要：

Hybrid Beamforming is an effective way to upgrade the performance of Massive MIMO(Multiple Input Multiple Output) system with reduced complexity and cost. For current wireless technology, MIMO-OFDM(Orthogonal Frequency Division Multiplexing) system is used to combat the frequency selective fading, by converting it to flat fading channel model. Assuming perfect Channel State Information is obtained, we consider a single cell downlink Multiuser Massive MIMO system to emulate the performance of various Precoding Techniques by varying number of users, number of data streams per user, MIMO configuration and modulation techniques using carrier frequency(fc) 28GHz. One-Ring based Scattering Channel model is used with number of Scatterers 100 distributed randomly around the user. Spatial Multiplexing technique is used at transmitter to increase the system capacity.
