Symbol-Level Mask-Compliant Hybrid Precoding for Multi-User MIMO-OFDM Systems
An MMSE-based block coordinate descent algorithm with closed-form subproblem solutions is proposed for robust hybrid precoding in MU-MIMO-OFDM systems under power, clipping, and OOB mask constraints, with simulations showing gains over benchmarks.
