Abstract :
In this paper, we study the impact of nonlinear amplification on average error rate of OFDM in Nakagami-m fading. We consider the conventional receiver (separate detection of each subcarrier) without any countermeasures against the nonlinearity to assess the pure joint effect of fading and nonlinear amplification. We present an approximate technique that allows to evaluate the average error rate in Nakagami-m fading in a closed form.
