The current 5G network needs to achieve a considerably larger link capacity and ultra-low latency to enhance mobile broadband and support emerging mobile applications and massive IoT. Thus, implementing MIMO-OFDM Spatial Multiplexing and Hybrid Beamforming techniques helped increase the information capacity using multiple transmit and receive antennas. At the same time, these can improve the Signal to Noise Ratio (SNR), reducing the interference that leads to lower latency. The whole system comprises four models, namely the antenna array, channel model, spatial multiplexing, and hybrid beamforming. They were designed and simulated using the MATLAB software, and each output produced in the previous model is being utilized in simulating the next one following a parallel design process. An antenna array was first modeled and was used for the subsequent channel model process. The outputs from these two are then used to simulate spatial multiplexing and hybrid beamforming. The results of each model were discussed and analyzed concluding that both transmission techniques are efficient tools for achieving the goals of the emerging 5G mobile technology. It provides a solution to the current difficulties being encountered by the 4G technology.
