Joint Source-Channel Coding for Broadcast Channel with Cooperating Receivers
It is known that, as opposed to point-to-point channel, separate source and
channel coding is not optimal in general for sending correlated sources over
multiuser channels. In some works joint source-channel coding has been
investigated for some certain multiuser channels; i.g., multiple access channel
(MAC) and broadcast channel (BC). In this paper, we obtain a sufficient
condition for transmitting arbitrarily correlated sources over a discrete
memoryless BC with cooperating receivers, where the receivers are allowed to
exchange messages via a pair of noisy cooperative links. It is seen that our
results is a general form of previous ones and includes them as its special
cases.Comment: to appear in Proceedings of IEEE Information Theory Workshop - Fall
