Effects of Amplifier Nonlinearities Without Amplitude Clipping
E. Costa et al [6] examined the effects of amplifier nonlinearities on OFDM transmission without clipping. The input-output relationship of the amplifier is given by
Equation 5.14
where
Equation 5.15
The AM\AM distortion model [28] is given by
Equation 5.16
where A is the saturation level of the amplifier, μ is the small-signal gain, and p is an integer. As P →∞, the AM\AM curve approaches ...
