Noun

pseudocodeword ‎(plural pseudocodewords)

1. (mathematics) The result obtained when a decoder fails to converge on a codeword, but instead converges on some other code structure.
   • 2004, IEEE International Symposium on Information Theory (page 67)

     We examine the structure of pseudocodewords in Tanner graphs and derive lower bounds of pseudocodeword weights.

   • 2008, Ming-Yang Kao, Encyclopedia of Algorithms (page 481)

     Other notions of pseudocodeword-like structures such as stopping sets are also known to coincide with these polytope vertices.
