Is it possible with GNU Radio to create a transmitter packet that has a
higher power preamble at the beginning of the packet? This could allow the
receiver to properly detect incoming packets. The data portion of this
packet could have reduced transmit power level. I am currently using
benchmark tx and rx files.
The magnitude of the transmitted complex vector determines the output
power (while in the linear range). If you set this magnitude to the
value that corresponds to the maximum power output level of the USRP
(just before clipping), you should be able to change it such that the
data portion is scaled to a lower level.
Actually doing this is left as an exercise for the reader.
