Multiple layered Reed-Solomon codes in audio disks with a feedback system

In this thesis, we study the performance of powerful multilayered Reed-Solomon error-correcting coding applied to audio disks to protect data from errors. A detailed analysis of the performance of four layers of Reed-Solomon coding is addressed in presence of burst errors. The application of Reed-Solomon coding in an audio disk is explored from a mathematical viewpoint. We propose to have a feedback system between layers of Reed-Solomon coding to facilitate the error correction. A successful simulation of the four layers of Reed-Solomon coding applied to audio disks is performed. Our simulation results combined with a U.S. patent by Shinya Ozaki indicate that there is an equivalent or an improvement in the performance of the system when the error correction system is assisted with feedback. We conclude with a discussion of the advantages and limitations of including such a feedback system.
