Efficient Processing of Signals with Natural Redundancy

This book offers new digital algorithms for processing audio and tonal signals having a high natural redundancy. The redundancy preserved in headers of compressed audio frames in MPEG-1 Layer 2 format.

Computer modeling proves an opportunity to detect and correct all catastrophic errors in three fields of a frame header. It was suggested that a Hamming error detection code with parity bits be used on the encoder end and transmitted over the existing low-speed channel to the decoder.
