Effects of Nonlinear Amplifier and Partial Band Jammer in OFDM with Application to 802.11n WLAN

Abstract

In this paper, we analyze the combined effects of nonlinear distortion and partial band jamming in an OFDM system through a Rayleigh fading channel. In addition to the effects of nonlinearity and jamming, the system is also subject to the channel estimation error. The nonlinear distortion is produced by a high power amplifier (HPA) located at the transmitter. The jammer is assumed to transmit a collection of single tone jamming signals which have a frequency off set with respect to the desired signal. The analytical model is then extended based on IEEE 802.11n standard. Finally, the simulation results are compared with the theoretical results.
