  • Sequential decoder for decoding of convolutional codes
    Patent number: 6690752
    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.
    Type: Grant
    Filed: October 22, 2001
    Date of Patent: February 10, 2004
    Assignee: University of Southern California
    Inventors: Peter A. Beerel, Keith M. Chugg, Recep O. Ozdag, Sunan Tugsinavisut, Sushil K. Singh, Phunsak Thiennviboon
