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. > Regards, > Neha. Good luck!
