Multigroup Multicast Precoding in Massive MIMO [PDF]
GLOBECOM 2017 - 2017 IEEE Global Communications Conference, 2017 Optimal physical layer multicasting (PLM) is an NP-hard problem that for simplicity has been studied under idealistic assumptions, e.g., availability of perfect channel state information (CSI), both at the base station (BS) and at the user terminals (UTs). With the advent of massive multiple-input-multiple-output (MIMO), PLM has become more challenging,

Secure multigroup multicast communication systems via intelligent reflecting surface [PDF]
China Communications, 2021 This paper considers a secure multigroup multicast multiple-input single-output (MISO) communication system aided by an intelligent reflecting surface (IRS). Specifically, we aim to minimize the transmit power at the Alice via jointly optimizing the transmit beamformer, AN vector and phase shifts at the IRS subject to the secrecy rate constraints as ...

Sum rate maximizing multigroup multicast beamforming under per-antenna power constraints [PDF]
2014 IEEE Global Communications Conference, 2014 A multi-antenna transmitter that conveys independent sets of common data to distinct groups of users is herein considered, a model known as physical layer multicasting to multiple co-channel groups. In the recently proposed context of per-antenna power constrained multigroup multicasting, the present work focuses on a novel system design that aims at ...

Multicast multigroup beamforming for per-antenna power constrained large-scale arrays [PDF]
2015 IEEE 16th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2015 Large in the number of transmit elements, multi-antenna arrays with per-element limitations are in the focus of the present work. In this context, physical layer multigroup multicasting under per-antenna power constrains, is investigated herein. To address this complex optimization problem low-complexity alternatives to semi-definite relaxation are ...
