Variable Redundancy Product Codes
Lih‐Jyh Weng, George Sollman · IRE Transactions on Communications Systems · 1967
The tensor product codes, as either iterated codes or error-locating codes, possess the property of variable redundancy (allowing up to eight different levels of error control). It is shown that the implementation of an encoder for such codes can be decomposed into the implementation of the component codes. The selection of eight encoder modes yields four iterated codes and four error-locating codes that lend themselves to both adaptive coding and feedback transmission strategies.
