Refined Strong Converse for the Constant Composition Codes
Hao-Chung Cheng, Barış Nakiboğlu · 2020
A strong converse bound for constant composition codes of the form P(n)e≥ 1-An-0.5(1-E0sc(R,W,p))e-nEsc(R,W,p)is established using the Berry-Esseen theorem through the concepts of Augustin information and Augustin mean, where A is a constant determined by the channel W , the composition p, and the rate R, i.e., A does not depend on the block length n.
