A system and method are provided for maximum likelihood estimation in a channel receiving data with inter-symbol interference (ISI). The method receives a serial stream of digital information bits. Decisions are made concerning the received information bit values, which the method accepts as processed information, with soft decisions (SDs) and corresponding initial hard decisions (HDs). The method then identifies a sequence of processed information in a correction matrix, and uses the correction matrix to cross-reference the sequence to a HD look-up value. In response to accessing the HD look-up value, a modified HD is created. The modified HD is decoded, for example, by using forward error correction (FEC), creating a decoded HD. The method compares the decoded HD to the initial HD, and updates the correction matrix HD look-up value in response to the comparison.
