Non-linear amplifier on the transmit signal of the impact is closely related with the modulation method. Different modulation methods, the resulting time-domain waveforms are different, such as for the European GSM mobile communications standard, the standard use of Gaussian minimum shift keying filter (GMSK), is a smooth change in the phase constant envelope modulation, so you can use non-linear amplifier to amplify, there is no envelope distortion, nor because of spectral regrowth and adjacent-channel interference.
