通道辨识的极小极大逆

Minimax Converse for Identification via Channels

Shun Watanabe

摘要:

推导出了通道识别的极小极大逆。利用这一逆,在不作强逆性假设的情况下,证明了一个与传输容量一致的识别容量的一般公式。进一步,给出了当I类错误概率不为零而II类错误概率为零时,信道识别的最优二阶编码速率的特征。我们的逆是建立在所谓的部分通道可解析性的方法,然而,极大极小的参数使我们能够规避文献中报道的缺陷。

英文摘要:

A minimax converse for the identification via channels is derived. By this converse, a general formula for the identification capacity, which coincides with the transmission capacity, is proved without the assumption of the strong converse property. Furthermore, the optimal second-order coding rate of the identification via channels is characterized when the type I error probability is non-vanishing and the type II error probability is vanishing. Our converse is built upon the so-called partial channel resolvability approach; however, the minimax argument enables us to circumvent a flaw reported in the literature.
