Abstract
An apparatus and a method is disclosed for correcting on-line error corrections in the digital transmission of voice or data utilizing forward error correction technique which avoids on-line calculations of the Massey or Berlekamp algorithms and the Chien search that it entails, and permits a simple hardware apparatus comprised of a ROM, shift registers, and exclusive OR gates, thus eliminating the requirement of a dedicated massive computer.
