Scale into a proper range before input to USRP

Hi all,

I was thinking about the ways of scaling the modulated complex(with
imag. part equals to 0) symbol to the range +/- 32767 which is accepted
by USRP. My idea is to find the output range (Min, Max) and first scale
to range(0, 65535) and then subtract by 32767 to drop in the range
(-32767, 32767). I was wondering if there’s any other solutions? Any
suggestions and advice will be appreciated.
