Dynamically Subarray-Connected Hybrid Precoding Scheme for Multiuser Millimeter-Wave Massive MIMO Systems

<div>Two subconnected architectures of the multiuser hybrid precoding in mmWave massive MIMO system: (a) conventional subarray architecture, where each RF chain is connected to a fixed subset of the antennas; (b) dynamic subarray architecture, where each RF chain is connected to interlaced antennas.</div>
