viterbi

Hello all,

I have a problem regarding using viterbi decoder in wifi.
I try to use hmmviterbi in GNU Octave , for decoding soft data (which was encoded with convolutional encoder with 3/4 rate) but met the following problem:
How I can create the TRANSPROB (transition probability) and OUTPROB (output probability) matrices.

Please help... Thanks in advance.
 

Re: viterbi

transition probabilities and output probabilities come from training. if u r using hmm then u first traing the system to obtain them.
