چکیده
1119 All Rights Reserved © 2013 IJSETR Abstract— In wireless communication systems, the design and analysis of an orthogonal frequency division multiplexing (OFDM) system signal is highly affected by the nonlinear effects of high power amplifier (HPA). The nonlinear effects of HPA on the OFDM system are the most critical because it is not only reducing the system performance but also creates interference on adjacent channels. This paper explores the analysis of nonlinear distortion effects in an OFDM system when the signal is passed through a nonlinear high power amplifier (HPA). Throughout this paper we also present the AM/AM analysis of HPA on OFDM. Finally we present the simulation results to show the nonlinear effects of HPA on OFDM.
