Abstract :
Real number data processing failures are detected by comparing parity values associated with a wavelet code which is most efficient in systematic form. Any rate k/n wavelet code, a form of real number convolutional code, is manipulated into a systematic wavelet subcode, with slightly reduced rate (k-1)/n, staying within the original algebraic structure.
