Peak-to-average reduction techniques

[osbourne]

Hi,

I need a method to reduce the peak-to-average ratio of multicarrier signals (e.g. 4 carrier UMTS signal) from about 11 dB to ~5.5 dB. I used a method called peak windowing, which results in a reduction to 7 dB. Is it possible to get a better result ?

regards,
Osbourne
