Re: Crop Signal Sub.vi block

Where does the Crop Signal Sub.vi show up? Can you link to the OFDM Streaming code you are referring to?

Re: Crop Signal Sub.vi block

Hi,

 

It looks like that is a subVI that was created for this project, so there isn't any documentation other then what the creator put in. Judging from the non-LabVIEW Comms version of the code it looks like it may be related to removing the cyclic prefix but I'm not certain. You may have to follow the logic to figure out what it does.

 

Sorry I couldn't be more help.

 

Cheers,

Michael
