I can't find your name in the list of my customers. All my customers must know other means like email than indirect communication through tihis MATLAB file exchange site. Anyway, I do not present the Simulink model files to my readers unless they are instructors who adopted my book as the text for their teaching since almost all the Simulink block diagrams in my book contain the parameters to be set and they are supposed to be composed by the readers as homework assignments. You know that most of my target buyers are students. If you are a professional who bought my book, I would give you a Simulink model you choose.

As I told above, the slides and programs are only the baits to fish the potential book buyers with. Even if you had bought the book "MATLAB / Simulink for Digital Communication" on Amazon, it is not easy for me to help you since I am tied up with authoring another book "MATLAB/Simulink for Digital Signal Procesing". However, in case you buy the book and send me the paper you mentioned above, I will take a glance at it to see what I can do. In any case, I do not guarantee I can help you. It is your job to modify the programs in the book in such a way they can accomodate your problems.

It is strange. I run the program with puncture=1 two times, once with EbN0dBs=2.6 and once with EbN0dBs=10 to get the following results, which seems fine since the BER has turned to decrease as the SNR increases. By the way, have you bought the book? If so, you must have got my email address. It seems that you have never rate this set of codes.
