[Discuss-gnuradio] signal to noise ratio and multiply const

[Baier]

Hi all,

I have simulated ofdm transmitter with 200kbps in grc. Without function 
multiply const I got a very bad spectrum mask of the transmiitter. If I 
insert the block multiply const with the 0.05 the spectrum mask and SNR 
will be much better (see attached pictures). How can I explain it? The 
dynamic range of the ofdm signal will be reduced if I insert the 
multiply const? That could be better for the amplifier (PAPR reducing)?
Thanks
A. Baier
