Abstract: Improved forward acting error-control arrangements, including encoders and decoders, are described for use in 2l-level data transmission systems which employ Gray coding to transform a binary source sequence into the 2l-ary transmitted sequence. The codes called i-compressed codes make use of the structure of binary codes and have the property that for some integer i, 1

Abstract: Apparatus is disclosed for performing Berlekamp''s algorithm to effect the decoding of binary BCH codes. In particular, in accordance with the present invention, Berlekamp''s algorithm is restated such that two variables are advantageously combined and a simplified circuit disclosed for performing the iterations specified by the restated algorithm.
