Abstract

Orthogonal frequency division multiplexing (OFDM) is an effective multicarrier modulation technique for high speed data communications which suffers from high peak to average power ratio (PAPR). And Wireless broadband (WiBro) is to provide high data rate wireless Internet access with PSS (personal subscribe station) under the stationary or mobile environment, anytime and anywhere for the future 4G communication systems. Hence, in this paper, bandpass memoryless nonlinearity effects are analysed with high power amplifier (HPA) for adjacent channel power ratio (ACPR) performance calculation of OFDM based WiBro system. The simulated performance of ACPR for this model is compared with the theoretical performance for the amplitude to amplitude (AM/AM) nonlinearities with additive Gaussian noise. The obtained ACPR shows good agreement with the theoretical performance.
