Abstract

The double-error correcting, triple-error detecting (DEC-TED) code can be adapted for use in a hybrid-error environment. The code is capable of correcting random errors and solid-burst errors in a mixed environment. The correction is obtained using the same decoder in one decoding pass. As an example, the (127,113) two-error correcting BCH code with one additional check bit can be used to correct phase-burst errors of length 9 or less, in addition to the correction of all single and double-random errors.

Error Correcting Code for Hybrid Errors

The double-error correcting, triple-error detecting (DEC-TED) code can be adapted for use in a hybrid-error environment. The code is capable of correcting random errors and solid-burst errors in a mixed environment. The correction is obtained using the same decoder in one decoding pass. As an example, the (127,113) two-error correcting BCH code with one additional check bit can be used to correct phase-burst errors of length 9 or less, in addition to the correction of all single and double-random errors.

The more important application is in the hybrid-error environment where the double-random errors are corrected in the conventional manner and, in addition, solid-burst errors of up to certain length are also corrected using the same decoder with an extended table. As an example, the (127,113) double-error correcting BCH code with one additional check bit corrects all phase-burst errors of lengths up to 9, in addition to the correction of all single and double-random errors.
