Hi: I have a question about the transmit amplitude. In the example file "transmit_path.py", the amplitude is range from 0 to 32768. But what does these number mean? Also, when the other GNUradio nodes receive the packet, how do I measure the receive power or the relative receiving amplitude?
Thanks in advanced!
