This paper considers random-coding bounds to the decoding error probability with maximum-metric mismatched decoders. Their error exponents are determined and the saddle-point approximation to the corresponding probability is derived. This approximation is accurate and allows for simple numerical evaluation, as verified for several channels of interest.
