Trellis diagram logical question?
how do you draw trellis diagram with a given free distance?
Say, d_free=5; how will a trellis diagram be designed...
I can do hit and trial, but is there some predefined way?
I also didn't see any youtube videos, and pdfs regarding this matter.Context-:I have the following question that I am trying to solve since few days-:Q) Applying 1/2 rate, 4-state convolutional encoder correct errors of 2 bits with the help of its trellis diagram.What I have doneI have knowledge of the convolution encoder. I knew the relation between states and design of convolution encoder.I learnt state table.I learnt that to correct 2 bits errors, you need d_free=5.
What I know-:
No of errors that viterbi can detect=d_free-1
No. of errors that viterbi can correct=MOD(d_free-1)/2
