1. A digital receiver comprising:
an equalization component to:
receive a signal comprising a sequence of symbols; and
generate an equalized signal with an estimated sequence of symbols corresponding to the signal; and
a decision generation component to:
detect that an aggregate error level associated with the equalized signal exceeds a saturation threshold level;
identify a set of errors comprising a first error associated with a first symbol having a highest error level and a last error associated with a last symbol; and
generate, based on the equalized signal, a decision comprising a sequence of one or more bits that represent each symbol of a first subset of the sequence of symbols and a confidence level corresponding to the decision, wherein the confidence level is based at least in part on a distance between an error level of each symbol and a level of the first error.
