Hybrid Precoding in Cooperative Millimeter Wave Networks [PDF]
IEEE Transactions on Wireless Communications, 2021 In this paper, we study the performance of cooperative millimeter wave (mmWave) networks with hybrid precoding architectures. Considering joint transmissions and BS silence strategy, we propose hybrid precoding algorithms which minimize the sum power consumption of the base stations (BSs), for both fully- and partially-connected hybrid precoding (FHP ...

Adaptive Hybrid Precoding for Multiuser Massive MIMO [PDF]
IEEE Communications Letters, 2016 Hybrid precoding (HP) is widely utilized in millimeter wave-based massive MIMO systems with significantly reduced radio frequency (RF) chains, but it requires a large number of analog phase shifters (APSs) and RF adders to realize the connection between RF chains and antenna elements.

Hybrid TH-VP Precoding for Multiuser MIMO [PDF]
IEEE Transactions on Vehicular Technology, 2017 Vector perturbation (VP) is a nonlinear precoding technique that achieves near-capacity performance in multiuser multiple-input multiple-output systems at the expense of large complexity due to the search for the optimum perturbation vector. In this paper, we present the hybrid Tomlinson–Harashima VP (TH-VP) algorithm, a novel zero-forcing precoding ...

Learn to Rapidly and Robustly Optimize Hybrid Precoding
IEEE Transactions on Communications, 2023 Hybrid precoding plays a key role in realizing massive multiple-input multiple-output (MIMO) transmitters with controllable cost. MIMO precoders are required to frequently adapt based on the variations in the channel conditions. In hybrid MIMO, here precoding is comprised of digital and analog beamforming, such an adaptation involves lengthy ...
