Design and Development of Extended Hamming code technique for SECDAEC in an audio signal

Single bit errors occur more frequently in memory elements. So for the avoidance of these single bit errors the Hamming code technique was recognized as the best among all other coding techniques. The most effective coding technique was Hamming [16, 11, 5]

which results in single error detection and correction as well as double adjacent error detection and correction. In this paper, a method to design SEC-DAEC codes with optimized decoding is presented and evaluated. Extended Hamming code is developed by adding an extra parity bit. The implementation is evaluated and compared by its application in an audio signal authentication in matlab with introduced errors The evaluations show there is a slight increase in area, power and delay of the decoder.
