Hierarchical Multi-Beam Search Based ChannelEstimation for Millimeter-Wave Massive MIMO Systems
Accurate channel state information (CSI) acquisition is indispensable for mmWave massive MIMO systems to perform sophisticated signal processing. The existing channel estimation methods such as beam training and compressed sensing either have low accuracy or require considerably high training overhe...
