Electrical Error-Correction Coding
September 28, 1998

• Digital communication systems, digital recording systems (CD), and some mass storage devices (RAID disks) rely on error correction coding to improve the quality of those systems.
• Since these systems process data at a very high rate, the error correction coding and decoding has to be done efficiently.
• Fortunately, error correction coding can be implemented using very simple and fast digital logic circuits.
• These circuits rely on some elementary operations with binary numbers.
