可变距离源的编码

Coding for Arbitrarily Varying Remote Sources

Amitalok J. Budkuley, Bikash Kumar Dey, Vinod M. Prabhakaran

摘要:

研究了无记忆远程信源的有损信源编码问题。源数据通过由对手控制的任意变化信道(AVC)广播。AVC的一个输出在编码器处被接收作为输入,并且另一输出在解码器处被接收作为边信息。假设对手非因果地知道源数据,并且可以采用与源数据任意相关的随机干扰策略。解码器从编码的消息和边信息重构源数据。我们证明了上界和下界的对抗率失真函数的源随机编码。此外,我们还提出了一般设置的一些有趣的特殊情况,其中上述界限一致,从而提供了它们完整的率失真函数特征。

英文摘要:

We study a lossy source coding problem for a memoryless remote source. The source data is broadcast over an arbitrarily varying channel (AVC) controlled by an adversary. One output of the AVC is received as input at the encoder, and another output is received as side information at the decoder. The adversary is assumed to know the source data non-causally, and can employ randomized jamming strategies arbitrarily correlated to the source data. The decoder reconstructs the source data from the encoded message and the side information. We prove upper and lower bounds on the adversarial rate distortion function for the source under randomized coding. Furthermore, we present some interesting special cases of our general setup where the above bounds coincide, and thus, provide their complete rate distortion function characterization.
