»Ø¸´£º [vhcg] about usage of puncture code

Hi, Jonathan
There is a variable "pattern" in the testbench0.v. You need set this variable by yourself. And there should be a depunture module, which is not include in this version, before the decoder. The symbols send to decoder are considered to have been depuntured. So two steps to solve this problem:
firstly,  send the depunctured codes to decoder in the testbench0.v. You can just replace this file "data/code" with a depunctured codes.
secondly, set the variable "pattern", in testbench0.v,  correspond with symbols in depunctured codes. For example, if k=3, you can set "pattern" as "3'b110".
 
Wish this will help you.

Hi, Johnson Zhu
I am studying your VHCG source code and try to use the generated code to decode punctured codes (the puncturing pattern is "110110" for every 6 codes, 0 means "puncture"). But the simulation results are not same as my matlab results. And I am sure the matlab results are correct. So would you please tell me how to use the puncture functionality in your delivery? It is not metioned in the specification and maybe I used it in a wrong way.

Regards
Jonathan
