Low Complexity Algorithms for Robust Multigroup Multicast Beamforming
Guangda Zang, Hei Victor Cheng, Ying Cui +4
Existing methods for robust multigroup multicast beamforming obtain feasible points using semidefinite relaxation (SDR) and Gaussian randomization, and have high computational comp…
Optimal Hybrid Beamforming for Multiuser Massive MIMO Systems With Individual SINR Constraints
Guangda Zang, Ying Cui, Hei Victor Cheng +3
In this letter, we consider optimal hybrid beamforming design to minimize the transmission power under individual signal-to-interference-plus-noise ratio (SINR) constraints in a mu…
