[Discuss-gnuradio] Scaling down IFFT values |

Hi All,
I need to scale down the OFDM transmission signal in time domain, after IFFT
is done, so that, all the values are within the range -1 to 1. But, I cant
simply add one more "scaling" block after cp_adder in
self.connect(self.preambles, self.ifft, self.cp_adder, self.scale, self)
(file: ofdm,py)
as it will scale down the preamble also, leading to non-recognition of
packet at receiver end.
Any pointer on where should I make the change?
