Hello users,

I have an ofdm based modulation and would like to reduce its peak to average without generating spectral regrowth.

Does clipping work at I&Qs ?

People came up with a bunch of PAR reduction techniques for OFDM so I guess this is more complicated than just clipping the base band data.

thanks
