Abstract :
The influence of bandpass non-linear distortion on an OFDM signal is investigated. The spectrum of the distorted signal and the resulting detection errors are determined. Non-linear distortion of OFDM signals can significantly increase the receiver BER. Previous analyses rely on simulation, or apply to specific non-linearities only. Here, an analysis is presented which is applicable to any weakly non-linear distortion of an OFDM signal. Simple analytical expressions are derived which allow a designer to choose parameters without performing simulations. Further, it is shown that the error on each OFDM subcarrier is approximately equally large
