Methods and systems for decoding data

摘要

A method 300 of decoding is presented. The method 300 includes the steps of receiving 302 a coded bit stream that is generated by encoding source information using a Non Return to Zero Inverted (NRZI) code, selecting an NRZI decoding method based on one or more parameters associated with noise in the received coded bit stream, and generating 306 a plurality of decisions by processing the received coded bit stream using the selected NRZI decoding method, wherein the received coded bit stream comprises a plurality of coded bits, and the plurality of decisions are estimates of a plurality of source bits in the source information.
