论文摘要
在分布式遥控器（CEO）源编码问题中，许多单独的编码器都观察到基础源的独立嘈杂副本。利率损失是该分布式设置所需的利率与编码器可以完全合作的设置所需的利率之间的差。从这个意义上讲，损失的特征是分布式处理的价格。我们调查并扩展了有关各种环境中速率损失的已知结果，并特别强调了观测值是高斯的情况，但是基本来源是一般的。
In the distributed remote (CEO) source coding problem, many separate encoders observe independently noisy copies of an underlying source. The rate loss is the difference between the rate required in this distributed setting and the rate that would be required in a setting where the encoders can fully cooperate. In this sense, the rate loss characterizes the price of distributed processing. We survey and extend the known results on the rate loss in various settings, with a particular emphasis on the case where the noise in the observations is Gaussian, but the underlying source is general.
