摘要

研究了一般信道下具有成本约束的信道编码问题。Verdú和Han导出了一般渠道的ε-容量。按照同样的证明思路,我们也可以推导出具有成本约束的ε-capacity。本文导出了成本约束下允许超支的ε-容量公式。为了证明这一定理,采用了Feinstein引理的一种新变体来选择满足成本约束的码字和不满足成本约束的码字。

Channel Capacity with Cost Constraint Allowing Cost Overrun
A channel coding problem with cost constraint for general channels is considered. Verdú and Han derived ε-capacity for general channels. Following the same lines of its proof, we can also derive ε-capacity with cost constraint. In this paper, we derive a formula for ε-capacity with cost constraint allowing overrun. In order to prove this theorem, a new variation of Feinstein's lemma is applied to select codewords satisfying cost constraint and codewords not satisfying cost constraint.
