Hi, all


         Currently, I am trying to establish a data transmission system using the Viterbi coding method as the channel coding.

         I found a problem that the output of the coding module is short type,

         Enc = trellis.encoder_ss(f, 0)


         While the decode module needs a float type

         Va = trellis.viterbi_s(f, K, 0, -1)


         Can some one tell me how to make them compatible?
