In this paper, we consider multi-quality multicast beamforming of a video stream from a multi-
antenna base station to multiple single-antenna users receiving different qualities of the …

In this paper, we consider multi-quality multicast of a video stream from a multi-antenna base
station (BS) to multiple single-antenna users requiring the video at different quality levels …

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 …

In this paper, we consider multigroup multicast transmissions with different types of service
messages in an overloaded multicarrier system, where the number of transmitter antennas is …

The demand for providing multicast services in emerging cellular networks is increasing.
This paper proposes a non-orthogonal transmission framework based on layered-division …

This paper considers the multi-group multicast beamforming optimization problem, for which
the optimal solution has been unknown due to the non-convex and NP-hard nature of the …

In this paper, multi-group multicast beamforming is considered with antenna selection.
Nonconvex joint problem is converted to an equivalent biconvex problem by using exact …

A multiantenna transmitter that conveys independent sets of common data to distinct groups
of users is considered. This model is known as physical layer multicasting to multiple …

In a multicast scenario, the performance is usually determined, and therefore limited, by the
weakest link present in the system. With multiple co-channel multicast groups, the problem is …

This paper addresses the problem of transmit beamforming for single-group multicasting,
where common information is transmitted to a group of users. Beamformers are designed to …
