Here's a really nice discussion on the topic:
My personal preference is to avoid any sort of clipping or forced peak limiting technique, because it introduces distortion and increases the BER. The tone injection idea seems clever, although it does increase the power requirements.

If computational complexity is not an issue then PTS scheme with all possible phases will give best result.

an advanced choice might be "constant envelope OFDM"

alongwith PTS if windowing is used , it will give better results.
exponential companding technique is also used.
