Shaped-Beam Subarrays for Equi-Power Urban Area Coverage With Modularity and Low Cost

Design of millimeter-wave arrays for base stations operating in dense urban environment is investigated. Innovative designs for linear subarrays with shaped beam patterns for hybrid beamforming are proposed. The number of elements and element spacings in the subarrays are optimally selected based on a pattern matching technique. The subarrays...

System Modeling and Simulation in 5G: A Hybrid Beamforming Approach With Power Flux Equalization in the Elevation Plane

This paper presents a 5G downlink system model for a hybrid multi-user beamforming technique at the base station. The presented technique employs power flux equalization in the elevation plane using a fixed analog cosecant-shaped beam and digital beamforming in the azimuth plane. The system performances of various beamforming algorithms are...

Active Multiport Subarrays for 5G Communications

A novel hybrid beamforming architecture based on aphased array of active multiport subarrays is proposed for multi-user 5G applications. The subarrays have multiple simultaneous fixed beams which are smartly combined at the user locations withrelatively large gains towards the intended co-frequency users and sufficiently low inter-user...
