[Discuss-gnuradio] A problem of the turbo channel coding!

[Shucai Xiao]

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?

 

Thanks
