Predicting the Power Spectrum of Amplified OFDM Signals Using Higher-Order Intercept Points
文献摘要：
Orthogonal frequency-division multiplex-ing(OFDM)has been developed into a popular modula-tion scheme for wireless communication systems,used in applications such as LTE and 5G.In wireless communica-tion systems,nonlinearity caused by radio frequency(RF)amplifiers will generate distortions to both passband and adjacent channels such that the transmission quality is degraded.The study of this article aims to predict the power spectrum for OFDM based signals at the output of an RF amplifier due to the nonlinearity.In this article,based on Taylor polynomial coefficients,a power spec-trum expression for amplified OFDM signals in terms of intercept points(up to nth-order)is derived.This model is useful to RF engineers in choosing and testing RF amp-lifiers with appropriate specifications,such as intercept points and gain,to meet the requirements of wireless standards.Measurements are carried out to confirm the results of the proposed model.
