Re: [Discuss-gnuradio] pad source&&Wifi physical layer input/output

[zhangwen]

Thank you nathan！
I have found another flow graph to implement the whole process of Wifi which contains hier block.
But I want to insert my own signal process block in pyhsical hier flow graph.
Is there any way to use pyhsical hier flow graph only?

Best,
Regards
