不同的远程源

Arbitrarily Varying Remote Sources

摘要:

我们研究了一个有损信源编码问题的任意变化的远程源(AVRS),这是在以前的工作中提出。AVRS发送符号,每个符号以独立且相同分布的方式生成,这些符号试图在解码器处被估计。这些符号是远程生成的,并且编码器和解码器观察通过双输出噪声信道接收的噪声损坏版本。该信道是由干扰对手控制的任意变化的信道。我们假设对手知道的编码方案,以及非因果关系的源数据,因此,可以采用恶意干扰策略与他们相关。我们的兴趣在于研究率失真函数的代码与随机编码器,即当编码器可以私下随机化,而解码器是确定性的。我们提供了这个率失真函数的上限和下限。

英文摘要:

We study a lossy source coding problem for an arbitrarily varying remote source (AVRS) which was proposed in a prior work. An AVRS transmits symbols, each generated in an independent and identically distributed manner, which are sought to be estimated at the decoder. These symbols are remotely generated, and the encoder and decoder observe noise corrupted versions received through a two-output noisy channel. This channel is an arbitrarily varying channel controlled by a jamming adversary. We assume that the adversary knows the coding scheme as well as the source data non-causally, and hence, can employ malicious jamming strategies correlated to them. Our interest lies in studying the rate distortion function for codes with a stochastic encoder, i.e, when the encoder can privately randomize while the decoder is deterministic. We provide upper and lower bounds on this rate distortion function.
