A Simple Derivation of the Refined SPB for the Constant Composition Codes
share
A judicious application of the Berry-Esseen theorem via the concepts of Augustin information and mean is demonstrated to be sufficient for deriving the sphere packing bound with a prefactor that is Ω(n^-0.5(1-E_sp'(R,W,p))) for the constant composition codes. The resulting non-asymptotic bounds have definite approximation error terms.
