Constrained Channel Decomposition-Based Hybrid Beamforming for mmWave Massive MIMO Systems
IEEE Open Journal of the Communications Society, 2020 In this article, we propose a hybrid beamforming design for multiuser mmWave massive MIMO systems. We adopt a two-stage approach for designing the analog and digital beamforming separately. The analog beamforming design is based on a constrained low-rank

Multiuser interference cancellation in time-varying channels [PDF]
The Journal of the Acoustical Society of America, 2012 In this letter, an adaptive time-reversal multichannel combiner is embedded within an iterative successive interference cancellation receiver. With the addition of matching pursuit, a sparse channel estimation technique, the combined receiver is shown to provide both temporal interference cancellation as well as spatial interference suppression in ...
