Abstract-- Broadcast (or point to multipoint) communication has
attracted a lot of research recently. In this paper, we consider the group
broadcast channel where the users' pool is divided into groups, each
of which is interested in common information. Such a situation occurs
for example in digital audio and video broadcast where the users are
divided into various groups according to the shows they are interested
in. The paper obtains upper and lower bounds for the sum rate capacity
in the large number of users regime and quantifies the effect of spatial
correlation on the system capacity. The paper also studies the scaling
of the system capacity when the number of users and antennas grow
