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!
