Angle-domain hybrid beamforming-based mmWave massive MIMO-NOMA systems
We design angle-domain schemes for mmWave assive MIMO systems using hybrid beamforming techniques. One is designed using only NOMA, and the other is a joint of TDMA and NOMA.

Multi-user angle-domain MIMO-NOMA system for mmWave communications
We propose an angle-domain NOMA scheme for mmWave MU-MIMO systems that uses only users’ angular information to boost sum-throughput, especially in congested cells. By designing new clustering, user ordering, and power allocation strategies based on angular metrics, our approach improves spectral efficiency by up to 39% and enables more effective interference management.

Multi-user digital beamforming based on path angle information for mm-wave MIMO systems
We evaluate the geometric features of conjugate beamforming and angle-domain digital beamforming for millimeter-wave communications using the NYUSIM channel model.
