You’re welcome. If by “any sample design which uses OFDM in version 13” you mean any file other than OptiSystem samples files (that work properly), unfortunately I don’t know any.
About the other question, I am not really sure, but you can make them using Matlab. I don’t think the first one is available. How is the second one you have mentioned different from the current position array capability which is available in OS 12 and OS 13 OFDM?
