This book contains the different puncturing patterns used in the WiMAX standards for different code rates 1/2,2/3,3/4 and 5/6.
The concept of the puncturing is very simple as I stated, and the MATLAB 2008 has a filed in the convenc command for the puncture pattern, If your research is mainly in Puncturing only, you have to search for detailed papers.
Search this book for the keyword puncture and you will find a very good three pages for this topic.
Good luck.

I am so sorry, I forgot that your research is on MIMO+STC.
I think that this document is enough.
Good luck.
Wishing you all the best.
