  1. Coordinated multicast beamforming for multi-cell massive MIMO systems

    Yin, ShiqiUniversity of Ontario Institute of Technology2023

    … approximation (SCA). To further design a fast algorithm applicable to massive MIMO systems, we apply the alternating direction method of multipliers (ADMM) technique and propose an ADMM-based first-order algorithm to solve the quality of service (QoS) problem, which decompose the QoS problem …

  2. Efficient design of reconfigurable intelligent surface assisted multi-group multicast beamforming

    Ebrahimi, MohammadUniversity of Ontario Institute of Technology2023

    … (RIS). We propose low-complexity scalable algorithms for the joint design of the base station (BS) multicast beamformer and the RIS passive beamformer to minimize the transmit power subject to the quality-of-service (QoS) constraints and maximize the minimum quality-of-service among all …
