Abstract : OGIC DECODINGThe concept of sequential code reduction (SCR), a new decoding concept devised by Drs. Luther D. Rudolph and Carlos R. P. Hartmann of Syracuse University, is used to achieve significant circuitry reductions in comparison to previous decoder implementations for a number of codes. For short block length codes the benefit is economy. For moderate to very long block lengths a sequential code reduction decoder may very well be the most cost effective or only solution to a communication problem. In addition to deriving basic SCR configurations, the author illustrates how easily the concepts of SCR and weighted erasure decoding (WED) can be combined to form a technique of decoding which uses likelihood information.
