Step Increment

• Definition:
  The step increment is how far the program will advance the Viterbi algorithm for one press of the STEP button. The step increment field is located just right of the step button as shown above. The possible values for the step increment are the following:
  

  By Branch
  By State
  By Trellis Section
  By Trellis Block
  Decode All
  

• Usage:
  To get the most detailed information about the execution of the Viterbi algorithm, change the step increment to "By Branch" or "By State". This gives specific information about the calculation of the branch and path measures. Choose "By Trellis Section" to step along with the time steps. If you want to skip ahead faster in the execution of the algorithm, change the increment to "By Block" or "Decode All" which act as expected. However, note that in the "Continuous" Decode Style There is no concept of a block, so stepping by trellis block is the same as stepping by trellis section.

  Note that the current step increment gets carried over to the next simulation when you press Restart.
