Transceiver Design with Hybrid Beamforming for Sub 6 GHz MIMO Communication

Wireless networks exploiting massive MIMO technologies come in handy to meet the demands of increasing data traffic and enhance network capacity and coverage for imminent communications. A large number of RF chains and energy-efficient antenna arrays are used on a broad scale to intensify the data rate and system throughput. This results in computational complexity and high energy requirements. To overcome this concern, a transceiver with Hybrid Beamforming is designed at 3.5 GHz (IMT range 3.5-3.8 GHz) using SystemVue© software. 3.5 GHz is preferred for its technical characteristics that make it effective in delivering high-speed services. It has the capacity to afford a considerable amount of contiguous spectrum that will support channels with wide bandwidth, ideal for 5G deployment. Transceiver designs with Hybrid Beamforming for sub 6 GHz MIMO systems with OFDM source are viable to reduce the volume of RF chains, disintegrating the signal processing into the analog and digital domains. Simulation results are analyzed based on various beamforming parameters like antenna array spacing, sidelobe suppression, directivity, beamforming gain and the use of a minimum number of RF chains is ensured. The proposed design provides a near-optimal performance close to the digital Beamforming with sharp beams.
