Coding Techniques for Multicasting
The multicast channel, which is composed of a transmitter and several receivers, is a special case of the broadcast channel,
where the transmitter broadcasts a message common to all receivers rather than private messages. The radio and TV
broadcasting are the simplest wireless multicasting examples. Besides, multicasting is of interest to cellular communications
in operations such as updating the cell parameters, broadcasting advertisements and public information.
Subscription to services is necessary for future multicasting scenarios, which makes the assumption of availability of the channel
state information at the transmitter (CSIT) convincing. It is well-known in multicasting applications that transmission rate is determined by
the weakest user in the system, since the transmitter's common message should be decoded perfectly by all receivers. It has been shown that multiple
antennas at the transmitter improves the performance significantly.
