Software Implementation of Error-Correcting Codes,

Abstract

Most error-correcting coding systems now use special-purpose hardware machines. The alternate method, using a general-purpose computer to perform encoding and decoding, has several advantages over the use of special hardware. Hardware equipment designed specifically for a coding system can be expensive, especially if the decoding is difficult, and if only a few systems are to be built. Minicomputers, however, are easily available and can be used throughout communications systems. To compare various coding systems in software, programs to perform encoding and decoding were written in assembly language for a PDP-11/40 minicomputer. The results obtained for decoding ease clearly depend on the programming techniques used, which in turn depend on the computer available. The codes implemented are compared in terms of error-correcting ability, and effort involved in decoding. (Modified author abstract)
