Hybrid Beamforming for mmWave-NOMA System Based on Beamwidth Adjustment
Abstract
In this paper, to overcome the difficulty of a narrow beam not being able to cover all users in the same cluster, we present a beamwidth adjustment-based scheme for non-orthogonal multiple access (NOMA) in hybrid millimeter wave (mmWave) communication systems. Our approach addresses the limitation of narrow analog beams by using a new hierarchical codebook based on NOMA to widen the analog beamwidth to cover all users of the same NOMA cluster. Simulation results demonstrate that our algorithm outperforms similar approaches in terms of performance.
