An Error-Correcting Encoder and Decoder of High Efficiency
J. Green, R. San Soucie · Proceedings of the IRE · 1958
A report is given on a group effort which has demonstrated the applicability of regenerative shift register sequences to error-correcting codes. It is shown that a triple-error-correcting code of high efficiency can be formed by using the 15 cyclic permutations of a 15-bit, maximal-length, shift register sequence, a 15-bit zero sequence, and the 1-0 complements of the 16 sequences. It is further shown that the interrelationships between the bits of these binary sequences can be used to design a decoder of extreme simplicity.
