本文考虑了随机编码对门限译码器译码错误概率的限制。一个略有改进的版本的依赖测试界。这个界限的松动产生了一个家庭的Feinstein的界限，这改善了Feinstein的原始版本。这些界限的误差指数的确定和简单的，但准确的，鞍点近似相应的误差概率。
This paper considers random-coding bounds to the decoding error probability with threshold decoders. A slightly improved version of the dependence-testing bound is derived. A loosening of this bound generates a family of Feinstein-like bounds, which improve on Feinstein's original version. The error exponents of these bounds are determined and simple, yet accurate, saddlepoint approximations to the corresponding error probabilities are derived.
