Hi Alistu,
Yeah true that. They have just implemented the prototypes of the designs and left it for the users to make necessary changes for their system requirements. But anyway it too helps a lot be it a prototype or just a single module of your system design present in the sample files. Gokul was looking for the paper from which DD-OFDM has been implemented but i don’t think he would be able to find it in any paper.
Regards
