Abstract: In underwater acoustics, environmental fluctuations can lead to a loss of coherence in sonar arrays. Among the various approaches that can be considered to mitigate their effects, sub-array ...
Sub-array based hybrid precoding design for downlink millimeter-wave multi-user massive MIMO systems
Abstract: In this paper, we investigate the downlink of millimeter-wave multi-user massive MIMO systems, and propose a hybrid precoding scheme based on a sub-array architecture to achieve a better ...
