ABSTRACT:
A simplified fast maximum likelihood decoder for (1-D) channels comprising a first stage decoder for detecting possible charge violations in a threshold decoded input signal, a second stage decoder for resolving charge violations detected in the first stage decoder by finding the most likely data pattern consistent with the charge constraint of the input signal, and an output shift register for generating corrected estimated decoded data in response to receiving control signals output from the second stage decoder.
