Hybrid Analog and Digital Beamforming for SU-MIMO Frameworks

Abstract

The analog and digital beamforming performing in hybrid manner that is by superimposing them altogether is the most appropriate scheme for MIMO systems to attain better performance. By utilizing this procedure the framework can lessen the equipment multifaceted nature, power consumption and can increase the spectral efficiency with a few number of RF chains. What’s more, interestingly, it’s general execution is the same as that of a hybrid beamformer’s structure. In this paper the hybrid beamforming structure for mm Wave frameworks with OFDM modulation is performed. That must be accomplished for the instance of single-user multiple-input multiple output framework, the hybrid beamforming architecture were implemented on its transmitter and receiver, and observe the results. That was the proposed idea. For this phase, there is only the transmitter portion of the proposed system is implemented. Expected result is the power spectrum of the transmitted signal. The generation of power spectrum to the hybrid beamforming is based on an analog steering vector designed under certain constraints. Only transmitted portion that is the inverse beamforming is done over here for this phase.
