This chapter works on crafting a generally enhanced transceiver explicitly for wideband multi-user (wMU) mmWave massive multiple-input multiple-output (mMIMO), aiming to maximize mutual information (MI). The proposed scheme follows the prevalent hybrid block diagonalization (HBD-)based framework and further proves that HBD is optimal in the sense of MI. Specifically, the transceiver design decouples hybrid processing into two-stage analog and digital processing, with which one can derive the MI bounds associated with HBD. After demonstrating the bound tightness, we obtain the excellent HBD transceivers by optimizing the lower bound. The proposed HBD technique does not rely on substantial computational complexity, striking channel sparsity, or high-resolution analog beamformers and can achieve a superb MI performance even with inferior hardware configurations.
