简单信道编码边界

Simple Channel Coding Bounds

Ligong Wang, Roger Colbeck, Renato Renner

摘要:

推导了单次使用任意信道的新的信道编码逆界和可复用界。这两个界限都是用一个称为“光滑0-散度”的量来表示的,它是Renyi的0阶散度的推广。在大块长度的极限下,也研究了其界。特别是,他们结合起来,给出一个一般的能力公式,这是相当于一个由Verdu和汉。

英文摘要:

New channel coding converse and achievability bounds are derived for a single use of an arbitrary channel. Both bounds are expressed using a quantity called the "smooth 0-divergence", which is a generalization of Renyi's divergence of order 0. The bounds are also studied in the limit of large block-lengths. In particular, they combine to give a general capacity formula which is equivalent to the one derived by Verdu and Han.
