Everything about BCJR algorithm

Error correction algorithm

The Bahl-Cocke-Jelinek-Raviv (BCJR) algorithm is an algorithm for maximum a posteriori decoding of error correcting codes defined on trellises. The algorithm was introduced in 1974 by Lalit R. Bahl, John Cocke, Frederick Jelinek and Josef Raviv, whose surnames give it its name. It applies to both linear block codes and convolutional codes. Wikipedia →
