A Statistical Channel Modeling for MIMO-OFDM Beamforming System in 5G mmWave Communications

The rapid increase of demanding data rates have push the button of aspiration to work with Fifth Generation (5G) network. Millimeter Wave (mmWave) with a wide bandwidth has made the path one step ahead to solve this problem. In this paper we consider a MIMO OFDM (Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing) beamformers for mmWave channels. Here we use statistical value of channel to make hybrid beamformers and hybrid combiners. As the RF (radio frequency) chain is short, we make a latest model comparing with previous one which can reduce the problem. Simulation results represent the enhancement of minimizing the loss of SNR, increasing the average SNR and transmission rate clearly.
