Abstract
A sequential decoder for decoding convolutional code is provided. The sequential decoder includes a computing device comprising a Fano technique. The Fano technique includes a plurality of variables that are normalized to change a point of reference of the technique. One of the variables is a current node metric. The variables are normalized such that the current node metric is set to approximately zero. Methods for using this decoder in applications that include periodic, hard deadlines such as real-time applications are also presented.
