多接收机协作广播信道的联合信源-信道编码

Joint Source-Channel Coding for Broadcast Channel with Cooperating Receivers

摘要:

众所周知,与点到点信道相反,分离的信源和信道编码通常对于在多用户信道上发送相关信源不是最佳的。在一些工作中,联合信源-信道编码已经被研究用于某些特定的多用户信道;即,多址接入信道(MAC)和广播信道(BC)。在本文中,我们得到了一个充分条件,传输任意相关的源在一个离散的无记忆BC与合作的接收器,其中接收器被允许通过一对噪声的合作链路交换消息。可以看出,我们的结果是以前的一般形式,并包括他们作为其特殊情况。

英文摘要:

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.
