Soft Input Soft Output Viterbi Algorithm

Implementation of the SISO Viterbi algorithm.

You are now following this Submission

Implementation of the soft input soft output Viterbi algorithm (SOVA) decoder. The implementation assumes that a finite length trellis window is available for both forward and backward recursions. Thus, it resembles well a hardware implementation of the SOVA decoder. Note: best performance on MATLAB R13!
