Abstract
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.
