Effect of Jammer on the Performance of OFDM In the Presence of Nonlinearity In Rayleigh Fading Channel with Application to 802.11n WLAN

In this paper, we present the performance analysis of an equalized OFDM system that is subject to nonlinear distortions from a high power amplifier (HPA), narrowband jamming interference and imperfect channel estimation in a Rayleigh fading channel. The analytical model is then extended to the Wireless Local Area Network (WLAN) system that is implemented based on IEEE 802.11n standard. Finally, the simulation results obtained from the extended model based on various sets of parameters are compared with the theoretical results.
