hi,
actually there is an inbuilt function - vitdec , which accepts the code to be decoded, traceback length, trellis structure, and two more input fields that decides the intial state of the shift register and decoding type ...
but if you want the code for this function, then its highly complicated, rather than understanding that code, you can come up with a better code, if at all u have comletely understood how a viterbi decoder works ...
peace upon you
my grdution project is in fixed wimax and i use vetrbi decoding in my implementation but when i use the vitdec function on matlab i found variable called traceback depth and i found that it is equal to 5 times the constrain length for rate 1/2.
but i couldn't find the value of this variable for other rates .
plz can any one help me??
