Abstract
A method and an apparatus for calculating an error metric in a digital communication receiver. In the receiver, an input data stream is used to generate at least one input bit stream. The combinational logic unit performs an error-check operation on delayed and current bits of the input bit stream using a polynomial error-check equation previously determined. Finally, an accumulator is used to accumulate a number of trials with respect to the error check operation and generates a nominal error-check number based on the number of the correct trials.
