Herein described is a system and a method of detecting and correcting data bit errors using a sequence of one or more codewords transmitted through a communication channel characterized by intersymbol interference. Each of the one or more codewords incorporates one or encodes one or more parity bits. The codewords are processed by a Meta-Viterbi detector that utilizes a Meta-Viterbi algorithm. The Meta-Viterbi detector comprises an event weight processor, a computational circuitry, a parity syndrome calculator, and an error correction circuitry. The Meta-Viterbi detector receives an output generated from a Viterbi detector having 2s states and processes the received output using a trellis diagram having 2t states.
