This paper investigates the joint design of hybrid transmit precoder and analog receive combiners for single-group multicasting in millimeter-wave systems. We propose LB-GDM, a low-complexity learning-based approach that leverages gradient descent with momentum and alternating optimization to design (i) the digital and analog constituents of a hybrid transmitter and (ii) the analog combiners of each receiver. In addition, we also extend our proposed approach to design fully-digital precoders…

Hybrid Precoding for Multi-Group Multicasting in mmWave Systems
This paper investigates the first joint design of hybrid transmit precoders and receive combiners for mmWave multi-group multicasting and demonstrates by means of extensive simulations that the hybrid precoder design performs very close to its fully-digital counterpart even under challenging scenarios.
Hybrid Precoding for Physical Layer Multicasting
This work proposes a low complexity algorithm to compute the RF precoder that achieves near-optimal max-min performance and derives a simple condition under which the hybrid precoding driven by a limited number of RF chains incurs no loss of optimality with respect to the fully digital precoding case.
